Regardless of which POE is used, the interface definition is uniform. The network port marked on the POE can connect to the network camera, switch, computer and other network devices on the POE. The network bridge equipment should pay attention to the connection to avoid burning the device.

4. The correct connection of network devices such as network bridges, POE power boxes, network cameras or switches. There are generally three interfaces on the POE power supply box: power interface (generally DC DC input), POE network port (only used to connect to the RJ45 port of the network bridge equipment), network port or LAN port (can connect to any Ethernet port port based on the Ethernet port) Network devices, such as: network cameras, switches, routers, computers, NVR, etc.).

5, network cable production standards and its type selection. The current standard of network cable production is generally made in accordance with the definition of the national standard. It is recommended to use the mainstream T568B line order standard to make network cables. The standards are as follows:

T568B: white orange, orange, white green, blue, white and blue, green, white brown, brown

The network bridge equipment uses POE power supply. It is recommended to use the national standard T568B line order production network cable. Since all network devices are adaptive Ethernet ports, when connecting the network bridge device to the POE or switch to connect to the POE, it is strongly recommended to use the national standard T568B class Class T568B The direct lines (that is, the two ends of the network cable are the line order of the national standard T568B).

6. Lightning protection treatment. The network bridge equipment is generally installed outdoors and the open area of lightning protection is needed. The equipment itself is built on the lightning protection protection circuit of the equipment itself. The correct lightning protection ground method is: the standing rod of the fixed net bridge is generally installed with a lightning rod. The grounding terminal of the net bridge needs to be connected to the earth with a lightning protection line.

7. Feed line connection processing. For outdoor high -power network bridge equipment, the external antenna is required to be installed far from the transmission distance, and the feeder connection is required between the antenna and the device. At this time, the connection parts of all feeders and the antenna must be treated with rainproof and dust -proof. It is necessary to wrap the two to three layers of waterproof tape or insulating tape, and try not to let the feed line connector exposed to the air.
