In situations where your Verkada Access Controller is powering locks or being used in critical safety applications, it is important to have backup power in the case of a power outage.
 
Battery Backup
Verkada sells the ACC-BAT-4AH for use with the AC41 Access Controller.
 
The Verkada AC41 can be powered by a 12V 4.5A sealed lead acid (SLA) battery as a backup power source. You can connect two batteries in parallel (NOT in series) to provide twice as much battery capacity.
