With the continuous improvement of the level of economic and social development in our country, people’s living standards are constantly improving, and many factors of social instability do not disappear with constant improvement. Therefore, people are paying more and more attention to life safety. In order to better create a good living environment, the monitoring system plays a role in escorting our lives. Ordinary monitoring systems are more troublesome to implement and affect the construction period and later maintenance. At present, the use of wireless monitoring equipment in the safe rural areas and safe cities to build wireless monitoring systems, so that many engineering providers really feel the wireless monitoring equipment is really easy to use, practical. In order to build a high-definition wireless monitoring system, what issues should we pay attention to? Shenzhen Leian Technology Xiaobian to briefly explain:
1. Image quality The quality of a million HD network camera is just as important as an ordinary surveillance camera. In this regard, you can only use the installation of different million HD cameras to observe the effect and choose a more suitable one million HD network cameras. It is advisable to have a prototype before the installation to test the customer and perform the batch installation with the final customer's choice.
2, network monitoring project audio function This is also taking into account the location you use to decide if you need to use the audio function of the million HD network camera, then you have to consider is to connect headphones or speakers, microphones and other equipment.
3, transmission environment Wireless bridge is the use of microwave signals to transmit video and other signals, then we must ensure that Lai-An technology wireless bridge in an open and unobstructed environment for transmission, in order to ensure the wireless monitoring equipment in the wireless monitoring system, stable transmission, Ensure the stability of the wireless monitoring system.
4, convergence layer switch selection:
The number of single-end IPCs connected to the front-end switch does not exceed 4, and 8-port 100-Mbit/s switches can be used. If more than 4 ports are used, 8-port Gigabit switches must be used, because the front-end switch uses only one network cable for transmission between the host and the main room. If there are too many IPC loads, packet loss, frame dropping, delay, and stalling may occur.
Note: The switch used in building a wireless monitoring system must use a dedicated monitoring switch. It cannot use normal switches that transmit network signals for transmission.
5, make a backup:
Before the construction, all IP cameras, network cameras, wireless bridges, NVRs, computer masters, storage servers, streaming media servers, high-definition decoders, and management servers in the system shall be uniformly modified and registered. , must pay attention to avoid the IP address conflict with the original equipment in the local network (such as computer, network printer);
6. Pay attention to the IP address conflict The IP addresses of all devices connected to the wireless network must not conflict. For example, IP addresses of all network devices such as network cameras, wireless bridges, NVRs, and computers must not conflict, but they must be on the same network segment. Inside.
7. Pay attention to the network cable selection. The camera can use the international Super Category 5 cable between the front end of the camera and the switch. The front-end switch must be connected to the main switch of the equipment room. Please use the national standard Category 6 network cable and the Category 6 crystal connector.
8. Pay attention to the length of the network cable In the wireless monitoring system, the choice of the network is very important. In the high-definition wireless monitoring system, we try to choose six or more types of network cable to build a wireless monitoring system. There is a certain relationship between the transmission distance of the network cable and the length of the network cable from the POE to the wireless bridge. If the cable length is too long, the signal attenuation is too large. The length of the network cable from the network camera to Shenzhen Lean Technology Wireless Bridge is generally less than 100 meters, and the length of the network cable between the receiving end wireless bridge and the monitoring center is also within 100 meters. If it is necessary to transmit a longer distance, it is recommended to use Optical fiber transmission.
9. The main switch in the equipment room The main switch in the equipment room must be a full-gigabit switch from a big brand, and must not be fully loaded. For example, if a 24-port Gigabit switch is actually used, you should not use more than 20 ports because of the high-definition video surveillance data of the network. The volume is relatively large and the data is continuously transmitted. The processing requirements for the switch are relatively high. If a switch has many points and there are delays and stalls, you can try to add a switch to solve the problem.
