Power over Ethernet Switch FAQs

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.

Q: What is a PoE Switch?

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.

Lorex 8+1 Channel PoE Switch (ACCLPS281B)

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.

Q: What is PoE+?

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.

NOTE: The Lorex 8-port PoE switch (ACCLPS281B) supports PoE Class 3 only. ACCLPS241B supports both standard PoE as well as PoE+.

Q: What Lorex systems are compatible with a PoE switch?

A: The PoE switch is compatible with Lorex NVR systems, such as LNR300 Series.

NOTE: The PoE is not compatible with LNR200 Series.

Q: What does 8+1 channel mean?

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.

Q: Do I need a router to connect IP cameras using the PoE switch?

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.

Q: How do I set up my NVR system using a PoE switch?

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:

  1. Connect an Ethernet cable from the LAN port on the PoE switch to your router. Connect the power cable to the PoE switch and to a power outlet or surge protector.
  2. Connect IP cameras to ports 1~8 on the PoE switch using the Ethernet extension cables. The PoE switch will provide power and video transmission the same way your NVR does.
  3. You must add the cameras to your NVR to view the cameras and enable recording. To do this, follow the steps in your NVR's instruction manual. Or, click here for details for LNR300 Series.

Q: Can I use the PoE switch to extend the IP cameras over 300ft from the NVR?

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.
