1, the first step is to install the camera: first fix the bracket on the wall, then fix the camera on the bracket, pay attention to the power plug, plug in the power supply, and then connect the connector and video cable to the camera.

2. Then install an optical cat at the entrance of the optical fiber. The optical cat can dial or add a router, and then the LAN port of the dialed router can be connected to the network camera with a network cable. When setting up a network video recorder, try to use static IP to avoid addressing conflicts with other computer terminals.

3. Finally, it enters the switch. The switch transmits the network signal to the transmitting end of the optical fiber transceiver (digital signal is converted into optical signal), and the transmission line enters the optical fiber, which is received by the receiving end of the optical fiber transceiver (optical signal is converted into digital signal) and enters the central switch. The center can manage videos with a management computer.
