JRI Wireless Monitoring System from FranceThere are indeed many advantages in practical projects, but in many instances, wireless monitoring systems still often encounter some problems. Of course, with the development of many projects, wireless monitoring devices will be used to build wireless monitoring systems. So, what aspects should we pay attention to in order to build a high-definition wireless monitoring system?

1、 Image and camera quality

The image quality of millions of high-definition network cameras is as important as that of ordinary surveillance cameras. Whether to choose standard definition or high definition should be decided by the owner or customer themselves. We only need to display the effect of the camera image.

2、 Network monitoring engineering audio function

According to the actual situation of the project, if a million high-definition network camera with audio function is needed, it is also necessary to consider connecting headphones or speakers, microphones and other devices.

3、 Transmission environment

Wireless bridges use microwave signals to transmit video and other signals, so it is necessary to ensure that the wireless bridge transmits in an open and unobstructed environment in order to ensure that wireless monitoring devices canWireless monitoring systemStable transmission ensures the stability of the wireless monitoring system. The installation location of wireless bridges should be chosen as much as possible in areas with smooth signal transmission.

4、 Selection of aggregation layer switches

The number of IPC connections per front-end switch should not exceed 4, and an 8-port 100Mbps switch can be used. If there are more than 4, an 8-port Gigabit switch must be used. Ethernet or fiber optic transmission should be used between the front-end switch and the main switch in the computer room. If there are too many IPC loads, packet loss, frame drop, delay, and stuttering may occur;

Attention: The switch used to build the wireless monitoring system must be a monitoring switch, and ordinary switches that transmit network signals cannot be used for transmission.

5、 Keep a good address record

Before construction, all network ball machines, network cameras, wireless bridges in this system need to be installed NVR、 Unified modification and registration of IP addresses for computer controllers, storage servers, streaming media servers, high-definition decoders, management servers, etc. It is important to avoid IP address conflicts with existing devices in the local network, such as computers and network printers;

6、 Pay attention to IP address conflicts

The IP addresses of all devices connected to the wireless network must not conflict, such as network cameras, wireless bridges, etc NVR、 The IP addresses of all network devices such as computers must not conflict, but they must be within the same local area network.

7、 Pay attention to the selection of network cables

Generally, 100Mbps switches use Category 5e Ethernet cables, while 1G switches use Category 6 Ethernet cables. Whether it is unshielded or shielded is not very important. If Party A specifically requires a better one, then low smoke halogen-free Category 6 shielded wire.

8、 Pay attention to the length of the network cable

In wireless monitoring systems, the choice of network is very important. In high-definition wireless monitoring systems, we try to choose Category 6 or Category 6A Ethernet cables to build the wireless monitoring system. Whether the network cable is good or bad, you can transmit it

The distance of the signal has a certain relationship, and the length of the Ethernet cable between POE and the wireless bridge cannot exceed 30 meters. If it is too long, the signal attenuation will be too large. The length of the network cable between the network camera and the wireless bridge is generally within 90 meters, and the length of the network cable between the receiving wireless bridge and the switch is also within 90 meters. If a longer distance needs to be transmitted, it is recommended to use fiber optic transmission.
