Curtain detectors are akin to setting up an electronic fence to protect or monitor long narrow areas.

Useful for setting a perimeter security system which enables you to move about inside the premises without setting off an alarm event. Monitor large openings such as vehicle garage doors, warehouse storeroom roller doors or vehicle gate entries whether the door is opened or closed.

Vast expanses of glass areas such as showrooms is another space highly suitable to utilise curtain detection to supplement your other intrusion devices.

Reduced false alarm events by the dual or triple beams which must be broken to create an alarm event.
