Intelligent high-level performance equipment providing cost-effective solutions to intruder detection alarm systems.

Central to our detectors is the Opal Elite, recognised as being one of the most innovative, flexible and cost-effective external PIR's currently available. This low voltage, weatherproof external device with two volt free timed contacts is designed to simultaneously or individually control not only lighting controllers, but also CCTV switchers and digital video recorders providing systems with a versatility that cater for any domestic, commercial or industrial requirement.

For distance perimeter protection, or just ease of installation, GJD’s Opal RFX provides an effective 35 metre wireless exterior movement sensor that can be sited up to 150 metres away from the control equipment. These products greatly reduce installation time and offer full detection coverage in hard to get to sites.
