For some NVR / IP camera setups, it may be necessary to use an external Power over Ethernet (PoE) Switch to expand your system to the maximum number of cameras. In other cases a PoE switch can help simplify or extend the wiring for your installation.
A: A Power over Ethernet (PoE) switch is a dedicated device that contains multiple Ethernet ports to provide power and network communications to IP cameras. This allows a PoE switch to expand the reach of an NVR system because you can connect IP cameras to the PoE switch rather than the NVR.

A PoE switch expands a network created by a router. Therefore, it must be connected directly to a router on the same network as your NVR.
A: High-powered IP devices such as PTZ cameras use PoE+ (also known as PoE class 4 or IEEE 802.3at), which provides more power to connected devices than standard PoE. Compatible NVRs use integrated PoE+ ports to provide power and PTZ commands to the camera, as well as video connection to the NVR.
PoE+ ports will provide up to 30W to each connected device, whereas standard PoE (class 3) ports only provide up to 15W.
A: The PoE switch is compatible with Lorex NVR systems, such as LNR300 Series.
NOTE: The PoE is not compatible with LNR200 Series.
A: The 8 refers to the number of PoE ports supported by the PoE switch. These ports are for the cameras, and provide both power and data transmission. The +1 refers to an additional port to connect the PoE switch to your router. It only supports data transmission.
A: Yes, you must connect the PoE Switch and NVR to a router on your network. A router is required to connect the NVR to the Internet and to connect devices within the system. The router will assign addresses to the IP cameras to ensure that any cameras connected to the LAN will be detected by the NVR.
A: See the diagram below of an example installation of a 16-channel NVR:
The steps to connect your system using a PoE switch are as follows:
A: Yes, you can connect the PoE switch to your router using a Cat5E or Cat6 Ethernet cable up to 300ft (92m) in length, and you can connect the IP cameras up to 300ft (92m) from the PoE switch.
This allows you to simplify the cabling for your installation. Because you can run cameras to either the NVR or the PoE switch, you can place the NVR and PoE switch in different parts of the building that are closer to the actual IP cameras.
See the diagram below for an example of how the PoE switch can help you connect cameras to the far corners of a large house.
