What fails when the lights go out.
WHAT STOPS WORKING
Cameras Recorders Alarms Electric gates and barriers Access control Lighting
WHY THAT MATTERS
Outages and break-ins correlate, and cover is lost precisely when needed.
WHAT TO ESTABLISH
Which security equipment has its own battery How long it lasts What happens when it is exhausted
WHAT TO CHECK ABOUT RECORDERS
Whether they continue recording on backup, or only the cameras stay powered.
WHY
Powered cameras with a dead recorder capture nothing.
WHAT TO PUT ON BACKUP
The whole chain: cameras, recorder, network equipment, and any remote connection.
WHY NETWORK EQUIPMENT
Remote viewing and alerts depend on it.
WHAT CONSUMPTION TO EXPECT
Modest, which makes this one of the cheapest things to protect.
WHAT TO DO ABOUT GATES
Establish manual release, and ensure staff know it.
WHY
Trapped vehicles and blocked exits are both safety issues.
WHAT TO TEST
The whole security system on backup power, periodically.
HOW
Cut mains and verify each element.
WHAT TO CHECK IN TESTING
That recording continues That alerts still send That batteries hold
WHAT TO REPLACE ON SCHEDULE
Small backup batteries in alarm panels, which fail silently.
WHAT TO DOCUMENT
What is protected, for how long, and what is not.
