Discreet yet effective security solutions

Based on infra-red technology, a beam alarm is triggered when someone passes through the beam and interrupts it. As the beam is invisible to the naked eye, it is a fantastic security system that is discreet whilst remaining highly effective.


At Trisec Ltd, we supply, fit and maintain a range of perimeter beam systems, from single units to monitor access, to advanced multi-sensor solutions that allow you to pinpoint when and where someone has entered your premises. Sensors can be set up to activate an audible alarm, notify security teams/the authorities, or send alerts to your phone. No matter your needs, Trisec Ltd is committed to helping you feel more secure.
