Perimeter Guard®

A camera that only records isn’t enough. Perimeter Guard® actively responds when someone lingers where they shouldn’t, letting them know they’ve been seen. 

You set the rules. Perimeter Guard takes it from there.

The first line of defense

Precise detection

Knows a lingering person from a passing vehicle so it only reacts when it should.

Set a schedule so Perimeter Guard only runs when you want it to.

Set it and forget it

Once configured, it runs on its own, no ongoing action needed.

Video Analytics

Every alert has a reason
