How is the Entry sensor powered?

The Entry sensor is designed to run easily and securely with standard IT networking equipment. The device is powered using Power over Ethernet (PoE) Plus — specifically using the 802.3at (PoE+) standard.

You can also power the device using a 30W PoE+ injector, which provides up to 30 watts of power from a standard wall outlet. The injector option can be helpful in the following situations:

• You don’t have PoE+ capable switches in your IDF or Network closet
• You are deploying the devices onto a Wifi or 4G network and don’t intend on running an ethernet cable from the switches in your network closet to each install location

What happens if I use PoE switches instead of PoE+?

On average, Density units will pull anywhere from 15-20 watts of power during normal operating mode. Every few milliseconds as the IR is emitting, those spikes can surpass 24w. If the port providing power to our device isn’t capable of providing up to 30w, the unit will power cycle. After 5 reboots, the device will enter a low power mode until a clean reboot is performed from the setup app or by Density Support.
