Power-over-Ethernet (PoE) with Alarm.com Cameras

Power-over-Ethernet (PoE) devices can provide and receive power through an Ethernet cable. PoE devices could be:

  • PoE Switch (connects and powers multiple PoE cameras)
  • PoE Injector (connects and powers one PoE camera)

There are however different kinds of power levels when talking about PoE. Some devices require more power like the ADC-VC729P PoE Floodlight Camera so make sure you check which one you may need. These are:

  • PoE 44-57V DC @ 15.4W (802.3af)
  • PoE+ 50-57V DC @ 30W (802.3at)
  • PoE++ 50-57V DC @ 60W (802.3bt)

Video devices capable of using Power-over-Ethernet only require one cable for both power and data. PoE cameras from Alarm.com cameras include:

  • ADC-VC727P (PoE 12.5W)
  • ADC-VDB755P (PoE 15.4W)
  • ADC-VC729P (PoE++)

The maximum distance that PoE can provide power is 100 meters (328 feet).

PoE Switch

A PoE switch would be used when powering multiple PoE cameras. When looking for a PoE switch, you will have to make sure that there is enough power provided by the switch to power all of your devices.

An example PoE switch is the TP-Link TL-SF1005P (4 PoE ports @ 67W total power).

The TL-SF1005P supports PoE and PoE+. It is not a PoE++ switch and therefore will not work with the ADC-VC729P PoE Floodlight Camera.

PoE Injector

A PoE injector works similarly to a switch but only provides Power-over-Ethernet to one video camera device. A PoE injector is also the most common type of device to power a PoE++ device like the ADC-VC729P.

An example PoE++ injector is the TP-Link TL-PoE170S which works great with the ADC-VC729P PoE Floodlight Camera.
