GJD Motion Detectors

The D-TECT X, D-TECT R Ricochet, Opal RFX and D-TECT LX models are. The GJD430 D-TECT X runs on 2 x 3 volt CR123 batteries with a 500m RF range on 868MHz, the GJD850R Ricochet pairs with Texecom Premier Elite panels, and the GJD018 Opal RFX sends triggers over 433MHz with a maximum communication range of 150 metres. The GJD1230 D-TECT LX reaches up to 10km on LX LoRa Connect, and the D-TECT Universal detectors connect to third-party wireless transmitter modules.

Yes, the D-TECT IP detectors do, using Power over Ethernet and an IP connection. The GJD230 D-TECT 2 IP supports direct integration with all major VMS and camera systems and is set up through a web browser. The GJD515 laser detector is PoE powered too, and each of its zones can trigger events over IP, such as sending a PTZ camera to a preset.

The anti-masking models are the ones to choose. The GJD359 D-TECT 50 AM uses an active infra-red sensor system to detect mask tampering and is BS8418 compliant, with a programmable detection range of up to 50 metres. The GJD300D D-TECT 2 has an active infrared sensor system to prevent mask tampering, and the Pearl GJD140 is a triple technology anti-masking curtain detector.

It builds invisible detection curtains from laser scanning instead of reading body heat. The GJD505 uses time-of-flight laser scanning to create up to four configurable curtains, with alarm and pre-alarm, in zones up to 5.0 × 5.0 m, and its IP65 housing suits indoor or outdoor use. The GJD509 extends the zone to 10 m × 10 m, and the GJD513 spotfinder helps locate a sensor’s infrared detection zone.

Yes, several are made to work with GJD lighting controllers. The Opal GJD020 is an IP55 external PIR with a 10 to 35 metre detection range that works in conjunction with GJD security lighting controllers, and the Mini Opal GJD332 is designed for outdoor use with GJD indoor lighting controllers. The Elite GJD023 adds two open-collector negative switching outputs for lighting or indication.

Because more than one sensor has to see movement before it signals, which cuts false alarms. The GJD660 D-TECT Universal Dual Tech uses a microwave and two independent passive infrared detectors, all of which must trigger to cause an alarm. The GJD310 D-TECT 3 pairs a quad-element PIR with a microwave sensor for reliable detection and false-alarm reduction, with a programmable range up to 30 m.
