Cables: Understanding Power over Ethernet (PoE)
Network systems with Power over Ethernet (PoE) use a single Ethernet cable to connect camera and NVR System. This cable powers the camera and transmits video at the same time.
Using PoE switches:
- A single run of Ethernet cable will provide power and video transmission up to 300 feet.
- If more distance is needed, a PoE switch can be used. A power-over-ethernet (PoE) switch is a device that contains multiple Ethernet ports that provide power and network communications to IP Camera. This switch allows you to expand the reach and also simplify the installation of an NVR System. Cameras plug into the switch, and (with the help of an ordinary router) just a single cable is needed to connect to the rest of your system.
- With the help of a Router, a PoE switch can minimize the wiring and extend the reach of your security installation. A PoE switch can also expand your network system to the maximum number of supported cameras.
