On some inconvenient or difficult wiring projects, wireless bridge as a transmission tool greatly shortens the construction period, saves costs, and simple installation. Wireless bridges can communicate in a variety of ways, including point-to-point, point-to-multipoint, and relay. Therefore, it is suitable for elevator monitoring system, construction site tower crane monitoring system, port and dock monitoring system, marine breeding monitoring system, traffic intersection monitoring system, forest fire prevention system and scenic town broadband transmission system, etc. Wireless bridges are usually used outdoors and are mainly used to connect two networks. It is not possible to use only one wireless bridge. Point-to-point must have more than two, and APs can be used independently. The wireless bridge has high power, long transmission distance (up to about 50km), strong anti-interference ability, etc. It does not have its own antenna, and is generally equipped with parabolic antenna to achieve long-distance point-to-point connection.

The wireless monitoring system is a combination of monitoring and wireless transmission technology. It can transmit the live information of different places to the wireless monitoring center in real time through wireless communication means, and automatically form a video database for later retrieval. The establishment of a wireless LAN depends on the specific environment. The wireless monitoring system is based on a monitoring system built on the wireless LAN. Therefore, the establishment of the wireless monitoring system should also be determined according to the specific environment, but in general, the wireless monitoring system has three modes, one is an outdoor wireless monitoring system, one is an indoor wireless monitoring system, and another It is an outdoor and indoor hybrid monitoring system. Outdoor wireless monitoring systems are used in some factories, they need to monitor the safety of various places; indoor wireless monitoring systems are used in industries such as mines, steel smelting, hotels and hotels; we do not monitor the outdoor and indoor hybrid monitoring systems.

What is a IP Cameras? The applications of electronic systems for security purposes have changed dramatically over the years. Unlike CCTV cameras with television lines, digital IP cameras are the next generation of surveillance system developed for a CCTV environment, but with better image quality, better resolution, and more everything. They generate an image directly from digital data with no continuous stream of analog video being broadcasted. They are more like the digitized version of CCTV cameras but with multi-user support meaning multiple users can use the cameras on multiple devices, plus advanced control features and flexibility to add unlimited cameras to the network without the need of any proprietary hardware. What is CCTV Cameras? The traditional CCTV cameras were primarily used for intrusion-detection applications mostly for alarm assessment purposes. That changed when solid-state cameras came to the picture in the mid-1980s and quickly became the standard for video surveillance because of their low maintenance cost and ease of use. Further advancement of technology and communication has pushed the limits of CCTV surveillance to an unprecedented level which results in an industry rich in computer and communication technologies. From an immature system to a full-fledge surveillance system, CCTV cameras has emerged as a standard for security industry. Difference between IP Camera and CCTV Technology involved in IP Camera and CCTV An IP camera is a networked digital video camera that transmits real-time video footage via a computer network and the internet. They are often used for IP surveillance, more like the digitized version of CCTV cameras with better picture quality and advanced recording functions. It is quickly becoming the standard for video surveillance. Closed-circuit television (CCTV) cameras, on the other hand, are used to transmit signal to specific place with a limited set of monitors within a closed system and is distinct from broadcast television. The network of CCTV cameras makes up a complete system. Flexibility CCTV depends on strategic placement of cameras and monitoring of the video footage on monitors and closed observation of the input. The cameras communicate via monitors and video recorders. Videos are stored digitally using a physical digital video recorder (DVR) across private coaxial cables or wireless communication links. Remote viewing is possible when the DVR is connected to the internet. IP cameras are generally plug-and-play devices that use NVR (network video recorder) rather than a conventional DVR to store digital content, plus they can be used in conjunction with CCTV cameras to have hidden cameras to cover blind spots. Broadcast Unlike analog CCTV cameras, IP cameras broadcast video footage as a digital stream of data over a computer network (LAN) or the internet to a network video recorder (NVR) through internet protocol. IP cameras need a connection to the same network as the NVR. They use PoE (Power over Ethernet) so that only one cable can be used for both power supply and video transfer eliminating the need for power cables. CCTV cameras send the video signal to DVR via coaxial cables, and the DVR then processes the signal for viewing. Unlike IP cameras, CCTV cameras require a direct link to the DVR. Expansion All the cameras in a CCTV system has to be placed in one location and the cameras require a direct connection to the base station or the DVR, so expansion of a CCTV system can be a whole lot pricey. Additionally, there`s only limited number of cameras that can be added to the network because a DVR is only able to accommodate up to 32 cameras, on the higher side and adding more cameras require an additional DVR. There`s no such limit on IP cameras and you can add almost any number of cameras to the network which would only require an additional storage without any major cost involved.

Home security is a kind of precautionary measure based on family safety. It uses physical methods or electronic technology to automatically detect the intrusion behavior occurring in the arming monitoring area, generate an alarm signal, and prompt the on-duty personnel to report the area of the alarm, indicating that countermeasures may be taken. system. The main purpose is to use the host to connect various types of detectors by wireless or wired to realize the anti-theft alarm function. With the emphasis on home security, home security applications are becoming more widespread. How to choose wired and wireless, home surveillance cameras need to be supported. The surveillance cameras in the home are generally not like cameras with large coverage and clear imaging in large buildings such as buildings and finance. In home security, surveillance cameras are generally used in conjunction with burglar alarms. After receiving the alarm from the burglar alarm, the user monitors the camera in time to check whether there is any intrusion or burglar alarm. All, when selecting a surveillance camera, it is not necessary to select a surveillance camera with high definition, long monitoring range and high price. If there is no one in the room for 24 hours, it is recommended to choose a surveillance camera with infrared night vision. However, some people will point out that while the burglar alarm is linked, if the thief invades and completes the crime within the time when the police effectively fires the police, then the high-definition surveillance camera should be selected for the police to follow the case to provide clues. Indeed, high-definition surveillance video can indeed increase the probability of solving crimes, but for ordinary families, the price of high-definition surveillance cameras is also very expensive. How to determine the pros and cons of an HD camera if there are individual users? To open this topic of choice, first of all, we must first understand your monitoring needs. How many cameras you need depends on what you need them to do. Do you need to install them indoors to monitor babies and babysitters, or do you need them to monitor the doorway or garden? You must also think about whether you need a video, so you also need to buy a video recorder. If it is a regular-sized apartment in a high-end residential area, then a burglar alarm is enough to meet the demand; if it is a regular-sized apartment in downtown, you need more than just an alarm. An outdoor camera will be more helpful for monitoring the outside space, like the garden and backyard. If the thief can see the camera monitoring them, they will not easily start with your house, especially when there are houses without monitoring equipment. In addition, what features do you want the monitoring system to include, do you want a wired or wireless camera? Wired surveillance cameras require construction wiring, and some changes are made to the building walls of the installation site during installation. These cameras should be in a fixed position and need to be rewired when moving the surveillance camera, which is cumbersome, time consuming and uneconomical for home users. Instead, the wireless camera you want to move anywhere, because it supports wifi wireless monitoring. However, their transmission signals may be blocked by mobile phone signals or wireless networks, which in turn affects the quality of video transmission. Wired products do not have this problem, providing higher resolution than the same wireless products. How to choose wired and wireless? Wireless network cameras need to work with wireless routers, and wireless routers require Internet access. Advantages of using wifi or 3g wireless network camera: no wiring is required, the number of cameras installed and increased is relatively convenient, and the cost of Internet access is relatively low. Such home network cameras are the market trend and mainstream. A wired network camera can be directly plugged into a network port or router that can access the Internet to work properly. Advantages of using wired network cameras: The technology is mature, and the industrial network camera technology is directly transplanted, not afraid of signal interference, stable and reliable, and the Internet access cost is relatively low. The disadvantage is that the installation is complicated, wiring is required, and it can only be accessed through a computer, and the scope of use is limited, which is not suitable for modern home use. If you support wireless network monitoring, there will be extra points. In the home monitoring products, what kind of products can achieve all-in-one? Since it is a network surveillance camera, the product will also meet a variety of network protocols. Not only that, but good wireless network functions highlight the convenience of civilian products. It is easy to install, requires no wiring, and has a wide range of applications.

Webcams are usually cheaper than a standard video camera and allow for face-to-face communication online, making it easy to illustrate things visually to the person you are talking to. This makes the webcam a very versatile device for home or office use. Webcams come in a wide variety of different models -- some are wireless and some can pan and zoom, while still others have movement sensors and night vision capabilities. Work Webcams are often used in the corporate world for video conferencing. Their use makes remote work possible. People who work from home can feel isolated from their colleagues, but through the use of webcams it is still possible to have a daily meeting. People who travel for work also benefit from the use of a webcam if their schedule doesn't allow them to be at the office for a meeting. Through video conferencing, experts from across the world can work together on a project and have a real-time brainstorming session. Personal Relationships A great advantage of having a webcam is that you can keep in touch with loved ones, while seeing their faces and expressions. It is a more personal experience than a traditional telephone conversation and a perfect way to maintain long distance relationships. People often use webcams for online dating and they are also used by people in the military, or others who travel a lot, to chat with their families at home. Education & Training Webcams make distance learning easier and more accessible. Students can request to speak to their lecturers via a webcam if they struggle to grasp something in the lesson plan. With the help of a webcam, the lecturer can explain certain concepts visually using sketches and diagrams. It is also possible to hold an online training session or study group with multiple students using webcams. Many online tutorials are recorded with webcams. Versatility There are many other applications for a webcam. Some programs can help you use it as video surveillance equipment. You could set it up to only survey your room, or set up multiple wireless webcams throughout a building as part of a security system. A webcam can also be used as a type of nanny cam. Many weather stations and nature parks use webcams and allow people to watch live feeds from the cameras. A webcam can also be used for home recording purposes -- for instance, when you need to send in a video clip for a competition or if you want to record a party or other event.

Let`s start with a little background. Our eyes see reflected light. Daylight cameras, night vision devices, and the human eye all work on the same basic principle: visible light energy hits something and bounces off it, a detector then receives it and turns it into an image. Whether an eyeball, or in a camera, these detectors must receive enough light or they can`t make an image. Obviously, there isn`t any sunlight to bounce off anything at night, so they`re limited to the light provided by starlight, moonlight and artificial lights. If there isn`t enough, they won`t do much to help you see. Thermal Imaging Cameras Thermal imagers are altogether different. In fact, we call them [cameras" but they are really sensors. To understand how they work, the first thing you have to do is forget everything you thought you knew about how cameras make pictures. FLIRs make pictures from heat, not visible light. Heat (also called infrared, or thermal, energy) and light are both parts of the electromagnetic spectrum, but a camera that can detect visible light won`t see thermal energy, and vice versa. Thermal cameras detect more than just heat though; they detect tiny differences in heat – as small as 0.01°C – and display them as shades of grey or with different colors. This can be a tricky idea to get across, and many people just don`t understand the concept, so we`ll spend a little time explaining it. Everything we encounter in our day-to-day lives gives off thermal energy, even ice. The hotter something is the more thermal energy it emits. This emitted thermal energy is called a [heat signature." When two objects next to one another have even subtly different heat signatures, they show up quite clearly to a FLIR regardless of lighting conditions. Thermal energy comes from a combination of sources, depending on what you are viewing at the time. Some things – warm-blooded animals (including people!), engines, and machinery, for example – create their own heat, either biologically or mechanically. Other things – land, rocks, buoys, vegetation – absorb heat from the sun during the day and radiate it off during the night. Because different materials absorb and radiate thermal energy at different rates, an area that we think of as being one temperature is actually a mosaic of subtly different temperatures. This is why a log that`s been in the water for days on end will appear to be a different temperature than the water, and is therefore visible to a thermal imager. FLIRs detect these temperature differences and translate them into image detail. While all this can seem rather complex, the reality is that modern thermal cameras are extremely easy to use. Their imagery is clear and easy to understand, requiring no training or interpretation. If you can watch TV, you can use a FLIR thermal camera. Night Vision Devices Those greenish pictures we see in the movies and on TV come from night vision goggles (NVGs) or other devices that use the same core technologies. NVGs take in small amounts of visible light, magnify it greatly, and project that on a display. Cameras made from NVG technology have the same limitations as the naked eye: if there isn`t enough visible light available, they can`t see well. The imaging performance of anything that relies on reflected light is limited by the amount and strength of the light being reflected. NVG and other lowlight cameras are not very useful during twilight hours, when there is too much light for them to work effectively, but not enough light for you to see with the naked eye. Thermal cameras aren`t affected by visible light, so they can give you clear pictures even when you are looking into the setting sun. In fact, you can aim a spotlight at a FLIR and still get a perfect picture. Infrared Illuminated (I2) Cameras I2 cameras try to generate their own reflected light by projecting a beam of near-infrared energy that their imager can see when it bounces off an object. This works to a point, but I2 cameras still rely on reflected light to make an image, so they have the same limitations as any other night vision camera that depends on reflected light energy – short range, and poor contrast. Contrast All of these visible light cameras – daylight cameras, NVG cameras, and I2 cameras – work by detecting reflected light energy. But the amount of reflected light they receive is not the only factor that determines whether or not you`ll be able to see with these cameras: image contrast matters, too. If you`re looking at something with lots of contrast compared to its surroundings, you`ll have a better chance of seeing it with a visible light camera. If it doesn`t have good contrast, you won`t see it well, no matter how bright the sun is shining. A white object seen against a dark background has lots of contrast. A darker object, however, will be hard for these cameras to see against a dark background. This is called having poor contrast. At night, when the lack of visible light naturally decreases image contrast, visible light camera performance suffers even more. Thermal imagers don`t have any of these shortcomings. First, they have nothing to do with reflected light energy: they see heat. Everything you see in normal daily life has a heat signature. This is why you have a much better chance of seeing something at night with a thermal imager than you do with visible light camera, even a night vision camera. In fact, many of the objects you could be looking for, like people, generate their own contrast because they generate their own heat. Thermal imagers can see them well because they don`t just make pictures from heat; they make pictures from the minute differences in heat between objects. Night vision devices have the same drawbacks that daylight and lowlight TV cameras do: they need enough light, and enough contrast to create usable images. Thermal imagers, on the other hand, see clearly day and night, while creating their own contrast. Without a doubt, thermal cameras are the best 24-hour imaging option.

Technology is a double-edged sword. While innovation and upgrades can have several benefits for us, they can also be used to cause trouble. The majority of us reap its advantages, but a few with vested interests continue to abuse it and make the lives for the rest of us miserable. The security camera is one of the wonders of modern technology, which is used at homes as well as in offices. It has gained immense popularity as an effective security measure, thanks to the plethora of benefits it offers. But just like other inventions, security cameras have a few drawbacks as well. The advantages, however, outnumber the disadvantages, and this revolutionary equipment continues to be popular with those serious about keeping their loved ones and assets safe and secure. If you`re thinking of installing security cameras at your home or office, but are still in two minds, this post should help clear your confusion. Advantages 1. DETER CRIME This is the biggest and the most obvious benefit of installing security cameras. Once they are placed, you will be able to see their effect on people almost immediately. Even if they are placed discreetly, you will start feeling a sense of security, which is priceless. Whether you install the cameras in your home or at the workplace, you can prevent crime from occurring. The mere sight of the camera staring back at them, and the sheer thought of getting caught red-handed are intimidating enough for mischief-makers to be on their best behavior as they would know that their identity and illegal activity have been captured. Whether you`re experiencing problems related to theft, punctuality, or productivity, your security camera can provide you with the solutions. It empowers you and prevents your home and office from becoming easy targets. 2. MONITOR SCENARIOS AND ACTIVITIES It is extremely easy to work with security camera systems as they can be placed anywhere as long as there is a power source close by. They come in all shapes and sizes; some are tiny enough to be hidden in plants, pictures, photo frames, etc. Depending on your needs you can buy either hidden cameras or mountable ones. Never let anyone or anything suspicious out of your sight with security cameras. And while it is recommended that you avoid buying dummy cameras, one cannot stress enough on the importance of fixing real cameras as a solid security measure. Criminals are smart and dummy cameras give themselves away, so there`s really no point in having them. Real cameras, on the other hand, are extremely helpful as they enable you to monitor the activities of people visiting your home and office as well as the goings-on at these places. This is a great way to detect suspicious people and keep tabs on their activities. 3. GATHER EVIDENCE Having cameras installed in strategic places comes in handy when you need to monitor actions and words of people or during an event. Modern security cameras are not only equipped with high-quality video capabilities, but audio as well. The clear images coupled with flawless sound makes them more efficient than ever at recording a series of happenings. This is particularly helpful when dealing with a legal scenario, wherein the eye witness may have forgotten a certain important detail or may be providing with an accurate account of what really transpired. With a security camera, the legal authorities can see the series of events as they really unfolded. 4. ARRIVE AT THE RIGHT DECISIONS Footage from security cameras can help you make correct and fair decisions when settling disputes, both in domestic as well as professional scenarios. Whether it is dealing with a situation involving disagreements within your family, among your employees, or between a customer and your service staff, your doubts can be laid to rest with the help of your camera. Incorrect, inappropriate or fabricated claims made by customers or other authorities can be sorted out when you make your security camera your ally. 5. MAINTAIN RECORDS So you got to know of something that happened outside your home or office about a fortnight ago and curiosity is getting the better of you? You can douse it by simply looking up your security records. Cameras record and document everything they see systematically, i.e. as per the date and the time of the event. Whether it is a crime or a minor tiff, your camera chronicles it, thereby making it easy for you to investigate the actual happenings. Disadvantages 1. PRIVACY IS AN ISSUE There have been a few instances in the past where security cameras have stirred up controversies, especially in professional setups. There have been cases where employees have objected to being under constant surveillance without their permission and citing the `invasion of privacy` as the reason. A few have also resorted to taking legal action against their employers in relation to this. Critics of security camera systems have taken offense to them being placed in offices and argued that doing so implies that the employer has either already assumed or is convinced that his employees are up to no good and will do something wrong which is why their activities need to be recorded. 2. IT CAN BE A COSTLY AFFAIR While dummy cameras may not be expensive, the real ones costs hundreds, even thousands of dollars depending on the features and the number of cameras and monitoring systems you buy. Getting them installed and their maintenance means added costs. If you`re thinking of installing them yourself, lay that idea to rest unless you have good knowledge of wiring systems or you may end up damaging the cameras. 3. THEY CAN BE VULNERABLE When we, as users of security cameras, try to keep ourselves updated on the latest in security systems, we should not forget that intruders and criminals are doing the same too. A clever trespasser will probably know all about them and may have figured out a way to go undetected. Further, tech-savvy criminals might have understood the technology and worked out ways to disable/disconnect them from their power source. Plus, if he detects your cameras as fake/dummies, they can be utterly useless in any crime prevention. In worst cases, hackers can play havoc with your security camera system by using the Internet and use them to spy on you instead. This makes security cameras vulnerable to damage and/or misuse. 4. CAN`T STOP THEFT Cameras enable users to record footage for later viewing, and to help nab criminals, and receive justice from the law. They cannot, however, stop a crime when it is in progress. They do not alert neighbors or the police like an alarm system would. This means that you will incur losses even as you run to the court, make insurance claims and reorder stolen inventory, which may no longer make you feel absolutely safe and even cause you to lose faith in them. Conclusion Before making the important decision of installing security camera systems, it is better to be equipped with complete knowledge about them, as that will enable you to make an informed decision and help you choose a camera that fulfills your needs and expectations. Once you`ve weighed the pros and cons of setting up this technological marvel, you will feel better about your choice.

WHAT ARE THE BENEFITS OF PTZ CAMERAS? Monitoring large areas: PTZ cameras are designed to cover very large areas such as farms, malls, parking lots, etc. It`s ability to pan, tilt, and zoom allows it to cover far more space than a traditional fixed camera. Typically these cameras are used to survey an area that would be too expensive or impossible to cover with fixed cameras Manually controlling cameras: with PTZs, personnel have the ability to look at exactly what they what, when they want. If an event occurs in a certain location and the offender takes off running this camera would allow the viewer to zoom in on his face and track him AS HE RUNS. Available Tours: A tour is a pattern that the PTZ camera follows on a specified schedule. For example: the camera could be set so that it`s constantly in a rotating pattern of looking at the gate, then an outbuilding, and then another entrance. This automated tour is an advantage from the standpoint that no one needs to be present in order to get these views. WHAT IS THE PRIMARY DOWNSIDE OF PTZ CAMERAS? Limited View: The major downside of PTZ cameras is their inability to record areas that the camera is not specifically looking at. For example, if the viewer moves the camera to view a certain location and an incident occurs somewhere else, the PTZ has no ability to capture that event. It is nice that it can be maneuvered but the downside is that it can`t see everything at once. For some, the camera application isn`t so cut and dry – [How can we have the ability to move our camera around but still have some coverage where the PTZ isn`t looking?" The answer is to utilize both a PTZ camera and several strategically placed fixed cameras, allowing for mobility without neglecting key locations. For example, pretend that you want surveillance at a large facility that has two major gate entrances and then two entrances going inside the building. In order to effectively monitor this location it would be best if fixed cameras were strategically placed at these entrances and gates (and possibly other key locations as well) with the ability to get facial recognition and license plate tags. Once key locations have been covered with fixed cameras, a PTZ camera could be added in order to survey the large facility. If an event is seen with the PTZ but the face is not recognizable then the viewer could look at one of the fixed cameras at the entrances to possibly indentify the suspect. A combination of PTZ and fixed cameras can provide a robust surveillance system. If you`re still unsure which type of surveillance camera is best for your business, contact our security experts at Security Alarm. Our team will be happy to answer your questions and help determine which solution is best for your needs.

A 4 in 1 security camera is one of the newest inventions in the surveillance camera world. This new bread camera allows users to use CCTV cameras and not have to worry about issues will compatible. Which is great news for everyone? As this allows people to add security cameras to existing systems or upgrade old cameras, as long as there is a BNC connection and power then this is a great option for anyone. With the ever-evolving world of surveillance cameras, this is a very important thing to consider as in the past all cameras worked with almost all recording systems. Whereas now we are dealing with analogue systems and HD systems. This has been known to cause many issues for many people but with the invention of the 4 in 1 the camera you no longer have to worry about this as this camera is compatible with old and new systems. 4 in 1 Camera Formats Most manufacturers have now worked together and created 4 in 1 cameras to support the transition from analogue to HD systems, allowing the user to easily switch between 4 formats to suit the format of the DVR. This gives the user many advantages, as you no longer have to worry about compatibility issues. These CCTV cameras are pretty much plugged and play. HD- TVI CCTV CAMERA Most commonly known as TVI this is the best type of analogue HD security camera on the market as it allows us to record and view the footage at an amazing 3-megapixel. This is by far the best mode to set your 4 in 1 camera up on any new HD system. AHD CCTV CAMERA AHD is a very common type of HD format behind TVI. As it is used on many budget surveillance camera systems from China. As this is a little more basic format the image quality is reduces comparing to its counterpart TVI. HD-CVI CCTV CAMERA HD CVI stands for high definition composite video interface. Was created by a company known as Duhua who are industry leaders in many aspects of CCTV. However, when they created this format of CCTV camera they limited peoples ability to uses different cameras with different DVR`s one of the Key reason 4 in 1 cameras where created and why they are so popular. CVBS CCTV CAMERA CVBS is an older analogue type of format typically deliver through BNC it can also be deliver through a phone connection. Which you would find on older types of cameras. This is the lowest quality format on a 4 in1 camera only to use on an analogue system. A huge advantage of using 4-1 cameras on an old analogue system is that if you want to add in a new camera to replace an old one you can set it to CVBS and when the rest of the system is upgraded at a later date you can simply switch the cameras to suit the DVR. Switching Between Camera Modes With a 4 in 1 CCTV camera, you have a couple of options to change the mode of the camera using the small joystick on the camera cable, you can use it in two ways. Firstly you have the option to switch the camera modes between TVI, AHD, CVI and CVBS. Most cameras will have a small diagram on the cable to let you know which direction you will want to push the joystick to activate the mode, for example, TVI may be on the right side of the switch so you would need to push the joystick in this direction and then hold it there for 5 seconds or more. The screen will usually then go blank while switching modes and then will reappear on your screen in the resolution you require. The second option you have is to use the on-screen display, which can be tricky if you have fitted the cameras, as you will not be next to your screen. A good tip ensures your cameras set up to the correct setting before you start installing. To display the on-screen display you will simply press the joystick in and this will then show you a selection list. Usually with options like the lens, exposure, white balance, backlight, day and night, reset. Depending on what camera you have purchased you will want to go through the settings until. You are able to find a setting for TVI or AHD switch until they give the correct resolution for DVR. One Camera to Rule Them All Wardmay 4 in 1 CCTV cameras are ideal for adding to any system. Allowing you to upgrade any excising system or put a brand new system in which will deliver exception image quality. 4 in 1 Cameras do it all and are one of the most important tools for CCTV tradesmen. As they are so versatile and allow you to work on almost any job.

CCTV is now something we take for granted. Many premises, streets and even homes are fitted with such technology and it is something we have come to accept and expect. Businesses and consumers alike can benefit from using it to boost security and to increase their peace of mind. Of course, the CCTV systems available today are very different from earlier versions. Here is a quick synopsis of the evolution of the technology. Live monitoring The earliest documented use of CCTV technology was in Germany in 1942. The system was designed by the engineer Walter Bruch and it was set up for the monitoring of V-2 rockets. It wasn`t until 1949 that the technology was launched on a commercial basis. In that year, an American government contractor named Vericon began promoting the system. These primitive solutions comprised cameras and monitors and they could only be used for live monitoring. They did not have components that allowed users to record footage. Primitive video recordings Later, primitive reel-to-reel recording systems were introduced to help preserve the data gathered. However, the magnetic tapes had to be swapped manually, which was a difficult, unreliable and costly process. Operators had to thread the tape from the reel through the recorder and onto an empty take-up real. Unsurprisingly, such systems were rare. The emergence of VCRs A major development in the history of CCTV occurred when video cassette recordings (VCRs) became widely available in the 1970s. This technology was quickly incorporated into surveillance systems, offering a new way for the cameras to be used. It was no longer necessary for people to monitor the screens live. Instead, the systems could be set up and left to run by themselves. Users could then review the information recorded as and when they wanted to. This made CCTV much more popular among businesses. However, it`s important to note that these solutions were far from perfect. The tapes had to be changed on a regular basis or re-written. If users wanted to store information for any length of time, they had to keep a library of tapes. Multiplexing Another significant development in the history of CCTV occurred during the 1990s, when multiplexing solutions became available. This technology allows video signals from a number of CCTV cameras to be combined and displayed on one monitor. For example, it means that if a company has four security cameras, each of these video signals is synchronised by the multiplexer and recorded on the same tape. This step forward made CCTV solutions more efficient and it helped to increase their popularity. Going digital Progress in digital technology since the turn of the millennium has led to further improvements. VCRs have been replaced with digital video recorders (DVRs), making CCTV systems simpler and more user-friendly. Multiplexers are now built into these solutions, meaning the kits are easier to install and operate. Digital systems have also removed the need for video tapes, meaning organisations no longer have to stockpile tapes in order to store information. NVRs Coming right up-to-date, it`s possible to purchase network video recorders (NVRs). These systems work by encoding and processing video in cameras and then streaming the footage to NVRs for storage or remote viewing. The solutions are particularly useful for firms with many site locations because they allow users to view various departments at any one time across the network or internet more easily and in higher quality than remote viewing with a DVR allows. Given the impressive features that CCTV products now boast and the ease with which they can be used, it is no wonder that the technology is in such high demand.

Some customers may be confused about which security camera system is right for them. Usually we recognize cctv systems for home and commercial CCTV Systems. There are many systems on the market that can qualify to both categories. But there are also systems specifically designed for home and cctv systems for commercial surveillance. So what are the differences? While surveillance systems designed for small business in many cases can be also used at home, there are some systems designed for commercial installations and you probably would not want to have them at home. The difference is usually not in quality or performance, but more in features. Systems designed for home usually are smaller in size. DVR units used for home surveillance usually are pretty small and quiet, so they can easily be located in the bedroom, living room, home office etc. Smaller, doesn`t mean lower quality. Those DVR usually record at the same quality and are capable of the same recording framerate as any commercial class Digital Video Recorder. But due to small form factor, usually there is only room for one hard drive, so storage space is limited. Also those DVR units rarely have Loop Out connection. There is limited number of Audio Inputs, Monitor Connections and there is usually no room for DVD burner for backup. DVR may not also support some network features like network backup to a server. Commercial DVR units often support Central Monitoring Software, so you can view several systems from one location. On the other hand, home surveillance often supports smartphone access, so you can view your home from work. There are of course Digital Video Recorders for home and for business supporting both features. So DVR for home surveillance is stripped from all the unnecessary features. Other than that it is still good quality product designed for long time operation. Cameras used for Home Surveillance are also usually just smaller. Not too many homeowners want to put big commercial cameras on their home. Same, as with DVR, Security Cameras for home surveillance are not necessarily lower quality. Usually it is the same resolution and quality, the only difference is in size, so if those are infrared cameras there will be limited range for night vision. For home surveillance we tend to use small bullet cameras or turret cameras. They are easy to install and blend into environment. Another difference is with cables. For commercial installations we tend to use Siamese Coaxial cable. It is much thicker than pre-made cctv cables, but it offers much better quality on long runs. For home surveillance, since most of the runs are within 200ft, we can use pre-made cables. They are a little more difficult to fish through the walls, because of the ends, but they are cheaper and thinner, so easier to conceal. And this is about it. As you see there are some differences, but rarely in quality. Of course I am not talking here about cheap home surveillance systems with plastic cameras and low resolution digital recorders, which you can find on store shelves of big box stores. So again, when comparing professional home surveillance and professional commercial cctv system, the difference is usually in the features not in quality.

When it comes to protecting your property there are multiple different solutions out there. Two of the biggest terms you have probably heard are CCTV camera and security camera. Knowing the difference between the two systems can help you to make the right decision. Today we are going to discuss the differences. CCTV Cameras CCTV stands for Closed Circuit Television. This technology uses cables to transmit signal from a camera to a monitoring station that is located remotely. Data is sent through camera cables to a monitor at a remote location but the data can also be recorded. However, there is a limit to how many devices that you can plug CCTV into. The technology used to power CCTV cameras is older and has less capabilities than what most people think of when they here the term security camera. These systems may be very basic but that comes with the benefit of being easy to control. You don`t need an extensive training and the systems are typically pretty intuitive. Another thing that you will notice about CCTV camera systems is that they will not have the highest quality images. In most cases, CCTV is limited to 720 HD image quality. For some purposes that might be all you need from your security system but it will not be the highest quality. The same thing that makes these cameras less advanced also works to protect them. Because the system uses cables to transmit the signal, it makes it much harder to hack the system. In order to hack the system, you would have to tap into the cables. That makes it hard for burglars to turn your system into their advantage. Security Cameras Modern security camera systems use a variety of technologies in order to transmit data to a monitor. The most common method is IP (internet protocol). This method sends the data over a local network so that you can view your cameras from anywhere on the network in real time. Because these cameras are attached to your network, they can be transmitted to internet so that they can be viewed anwhere. That means you can watch these camera systems from anywhere you have internet access. This is how security monitoring stations and the police can have access to your camera system. Cameras that work on internet protocol have a large amount of features available. Pan, Tilt, Zoom camerasare an example, with PTZ cameras you are able to move them around in order to get an image of anywhere in an area. You can also get cameras with 1080P HD or higher. With the highest in HD quality, you are able to make out every last detail. Networked cameras are more accessible to outside forces because the signals are digitalize. There have been cases in the past where security camera systems have been compromised. Measures have been taken to prevent this and it happens rarely. Security cameras are often considered to be the best option in a modern environment. Access to the additional features offered by a security camera system tend to make it a great option for any environment. No matter what kind of security camera system (or CCTV system) that you want to install, it can be a difficult process. Hiring a professional installer for your system is the best option.
