Alarm.com ADC-VDBA-PM Video Doorbell Power Module

Product Description

The ALARM.COM INCORPORATED ADC-VDBA-PM is a power module designed to supply stable, consistent power to compatible Alarm.com video doorbell installations. This accessory addresses one of the most common issues in video doorbell deployments: insufficient power delivery from existing doorbell transformer wiring. It integrates into the low-voltage doorbell circuit and conditions power output to meet the operational demands of a video doorbell unit. Installation is typically performed by a licensed low-voltage or alarm technician during a new doorbell camera setup or as a retrofit to an existing system.

The ADC-VDBA-PM is suited for residential installations where existing doorbell transformer output may not reliably support the power draw of a video doorbell. It is used in conjunction with Alarm.com video doorbell hardware as part of a broader smart home security system. This module is especially relevant in older homes where transformer capacity is limited and video doorbell performance suffers from voltage drop or brownout conditions during peak demand.

Key Features

• Designed to stabilize power delivery for video doorbell camera installations
• Supports low-voltage doorbell wiring circuits common in residential construction

Installation Notes

Installation should be performed by a qualified low-voltage or alarm technician familiar with doorbell wiring circuits. Power down the existing doorbell transformer at the breaker before beginning any wiring work. Follow applicable NEC guidelines for low-voltage wiring. Do not exceed the rated input voltage of the existing transformer when wiring this module into the circuit.
