Alarm.com ADC-VDBA-PSU-DC Doorbell Wall Power Supply

Product Description

The ALARM.COM INCORPORATED ADC-VDBA-PSU-DC is a wall-mount DC power supply designed to support video doorbell installations where a standard low-voltage doorbell transformer is absent or insufficient. It connects directly to a standard AC wall outlet and converts line voltage to the DC output required by compatible Alarm.com video doorbell units. Installation is typically performed by a licensed electrician or a security systems technician familiar with low-voltage device wiring. This unit ships as a single piece and is sold individually.
