Detectors

Intruder alarm detectors for accurate motion detection in domestic and commercial alarm systems, including passive infrared (PIR) detectors, dual-technology (PIR + microwave) detectors, pet-immune PIR detectors rated to 25kg, curtain detectors, outdoor PIRs, and vibration detectors. Our range includes products from Texecom, Pyronix, Ajax, Optex, and Hikvision, covering Grade 2 and Grade 3 EN 50131 applications.
PIR detectors are the most widely used sensor type in UK intruder alarm installations. Dual-tech detectors combine PIR and microwave sensing to dramatically reduce false alarms in challenging environments. Pet-immune models use passive compensation algorithms to ignore animals below the specified weight threshold. Evolution Electronics supplies intruder alarm detectors with fast UK dispatch and competitive trade pricing.
