The Density 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 ethernet cable from the switches in your network closet to each install location
