POE power supply for network camera.

It should be the quality of the network cable. Normal POE is connected to 80 meters, but a good cable can be pulled to 100 meters. However, the wiring modification project is a bit too big and troublesome. You can separate this camera, connect 4 and 5 to the positive electrode 7 and 8 to the camera through the network cable with a 3 4A power supply, which is separate from the original POE. Four wires are connected to the network cable and four wires are connected to the power supply.
