Charge the ADC-VDB781B battery
There are two methods for charging the Alarm.com Battery Doorbell Camera (ADC-VDB781B) battery, and both methods can fully charge the battery in less than 5 hours.
Charging methods
- Wired charging. Charge the battery pack via a connected AC transformer or DC power supply.
- Removed battery charging. Remove the battery pack and charge it while separated from the camera.
Wired charging
- Wired charging is supported when there is at least 8 VAC/60 Hz, 10 VAC/50 Hz, or 5 VDC delivered to the doorbell. This translates to generally 12 VAC at the secondary of a transformer.
- The battery will be charged via the contact pins if the minimum power requirements are met, and will continue charging the device until the device's charge level is between 80–90% of the maximum to protect the longevity of the battery pack.
For detailed wiring steps regarding the ADC-VDB781B, see ADC-VDB781B wiring guide.

It is recommended to be proactive about charging the battery before the device is in a Low Battery and Low Temperature state (i.e., less than 20% and less than 32ºF), and to set it up for charging as soon as possible once it is in a Low Battery and Low Temperature state.
The battery status indicator icon is displayed across all video streaming interfaces within the Alarm.com app, except for the Multi-Video Feed Grid View, Siri Shortcuts, and TV interfaces. Additionally, the battery indicator is visible in the ADC-VDB781B video settings within the Alarm.com app.
Tapping on the battery indicator icon will display an informative message and guidance within an action sheet for each unique status.
