Ten precautions for the installation of wireless video surveillance systems With the continuous improvement of current wireless technology, the application fields of wireless video surveillance systems are becoming more and more extensive. Here are a few things that need to be paid attention to when installing wireless video surveillance systems for the majority of users. 1. Surveillance object The surveillance object determines the viewing range, camera position, and the type of camera required. The surveillance object can be divided into a detailed image and a general observation image. Subtle images are good for identifying people or specific targets, such as human faces, credentials, and sales store monitoring; general observation images are mainly to monitor the entire scene or the approximate flow of the scene. The monitoring target determines the viewing range, camera position, and the type of camera required. 2. Monitoring range Depending on the coverage area, the type of HD network camera and the number of HD network cameras can be determined. In a project, the selection of the lens is very important, it depends on whether it can cover the entire scope of the customer's need to watch. 3. Monitoring environment Because indoor and outdoor light is different, sensitivity and lighting effects must be considered. Infrared lights can be used in outdoor environments, and some need to use day and night surveillance cameras; if it is indoors, there is generally no need to consider so much, as long as the lighting effect is considered. In addition, if you are outdoors, you have to consider factors related to dust, moisture, water, and vandalism. For example, in a dark environment, a camera with low illumination function can be used, a camera with a wide dynamic function can be used in an environment with uneven light distribution, a professional license plate function camera can be used in a bayonet environment, and a dedicated elevator can be used in an elevator environment Camera and so on. 4. The choice of aggregation switch The national standard Category 5 network cable can be used between the IPC and the front-end switch, and the national standard Category 6 network cable and Category 6 crystal plug must be used between the front-end switch and the main switch of the computer room. Our current projects basically use optical fiber transmission, single-mode and multi-mode, free choice. Fiber optic transceiver or optical module, free choice 5. The core switch selection must choose a big brand full gigabit switch, and must not work with full load, such as a 24-port full gigabit switch in actual use, generally do not use more than 20 ports, because of the network The amount of HD monitoring data is relatively large and the data is continuously transmitted, and the processing requirements for the switch are relatively high. If there is a delay or stuck phenomenon when a switch has many points, you can try to add another switch. To solve it. As for the core switch with or without routing function, choose according to your needs. 6. The choice of access switch The actual bandwidth of our commonly used switches is 50%-70% of the theoretical value, so the actual bandwidth of a 100M port is 50M-70M. 4M*12u003d48M, so it is recommended that one 100M access switch can connect to 12 720P network cameras. At the same time, considering that the current network monitoring adopts dynamic encoding, the peak value of the camera code stream may exceed 4M bandwidth, and the bandwidth redundancy design is also considered. Therefore, a 100M access switch is controlled within 8 units, and it is recommended to use Gigabit ports for more than 8 units. 7. Write addresses in advance. Before construction, the IP addresses of all network domes, network cameras, NVRs, computer masters, storage servers, streaming media servers, high-definition decoders, management servers, etc. in this system must be uniformly modified and registered. Be sure to avoid IP address conflicts with original devices in the local network (such as computers and network printers). The addresses of all equipment must be drafted, and the addresses of the cameras must also be marked on the drawings to facilitate maintenance by after-sales staff. 8. The choice of network cable The national standard super five network cable can be used between the IPC and the front-end switch, and the six network cable is gradually applied to the security system. 9. Data encryption security Some need to consider the HTTPS encryption that encrypts the video stream and then transmits it over the network, allowing or denying access to the IP address filtering that defines the IP address, and the IEEE802.1X, IPv6, and wireless functions that control network access. Of course, these functions are not needed under normal circumstances. 10. Hidden surveillance Because some places need to install hidden millions of high-definition network cameras for some specific reasons. So in this regard, you have to consider choosing non-concealed or concealed surveillance cameras.
