Network cameras are powered via Ethernet cables. The camera focal length has been calibrated, and the camera IP and program version have been correctly set at the factory, requiring no modification.
Power on the switch, insert one end of an Ethernet cable into the switch, and the other end into the network port of the camera's tail cable. When the camera's digital tube lights up, it indicates that the camera has been successfully powered on.
Connect the computer to the switch using an Ethernet cable.
