The Alarm.com ADC-W110 is an ethernet to WIFI bridge that is used with hardwired ethernet devices and power over ethernet (PoE) cameras. This converter module allows compatible hardwired devices to communicate across a local WIFI network. Instead of running ethernet wire to a device, you can eliminate the need and use this bridge instead. The ADC-W110 is intended for Alarm.com cameras that use PoE but can be used with almost any wired ethernet device. Both power and IP data will be supplied to the PoE camera thanks to the W110 - Please note that the W110 wil still need to receive power from an outlet.
