Cable Length Extension - EverFocus ENVR8304D User Manual

2.3.2 Cable Length Extension

The Ethernet connection is effective within 100 meters in distance. If the distance between the
PoE switch and the IP cameras is over 100 meters, you need to use a hub, PoE injector or PoE
extender, which should be connected to one camera only.
Note:
1. It is required to provide power supply additionally for the camera connecting by a hub
for extension.
2. For stable connection and operation, the user should establish a dedicated
communication line for IP cameras in the same network so that the router connection is
not allowed.
