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.
