Burglar Alarm Sensors
Burglar alarm sensors detect an intruder moving through a protected area and signal the alarm panel. This page has indoor PIR and dual-technology detectors, ceiling-mounted 360° sensors, curtain detectors for windows and doorways, outdoor perimeter detectors and detectors with built-in cameras for photo verification, in wired and wireless versions from makers such as Ajax, GJD, Texecom, Optex, Pyronix and Hikvision.

Choosing Burglar Alarm Sensors
Match the detector to the space it has to cover and to the alarm system it reports to.
Detection technology
Dual-technology detectors add a microwave sensor to confirm the PIR, which helps near air conditioners, fireplaces or large windows: the Pyronix KX10DTP3 needs both sensors to activate before it alarms. Anti-masking models, such as the Aritech VE735AM, the Texecom AKE-0001 and the Ajax 117717.09.WH1 Superior MotionProtect G3 Fibra, detect attempts to cover or block the detector.
Coverage and mounting
Wall detectors cover a fan-shaped area: the Texecom AKE-0001 covers 20m at 85°, and the Eaton DET-WPIR-00 has 54 zones over 90°. Ceiling detectors such as the Pyronix OCTOPUSDQ and the Texecom AKF-0006 Capture CQ give 360° coverage. For long corridors, the Texecom Capture LR50 (AKW-0001, GDF-0001) is a 50m long-range PIR, and curtain detectors such as the Optex TXI-DAM-X8 and the Ajax 101441.289.WH1 Curtain Outdoor Jeweller guard a narrow line across windows, doorways or fences.
Wired or wireless
Ajax Jeweller detectors pair wirelessly with an Ajax hub, and the Ajax 44404.09.BL1 MotionProtect Fibra runs on a wired two-way Fibra bus. Texecom Ricochet detectors such as the GDC-0006 Capture D20-W join a wireless mesh, and the Hikvision DS-PDD12P-EG2-WE belongs to the AX Pro wireless series.

Outdoor and perimeter detection
The GJD300D is a BS8418 compliant quad PIR with a programmable beam range of up to 30m that avoids boundary overspill, and the GJD230 is a PoE IP version that integrates with VMS and camera systems. The Ajax 36662.121.WH1 MotionCam Outdoor adds a camera that sends photos to verify an alarm.

Frequently asked questions
What is a dual-technology motion detector?
A detector that pairs a PIR with a microwave sensor and raises an alarm when the two sensors agree, which cuts false alarms in rooms with heat sources. The Pyronix KX10DTP3 needs both sensors to activate, the Ajax 143623.02.BL1 Superior MotionProtect Plus Fibra adds a K-band microwave sensor that activates when its PIR triggers, and the Hikvision DS-PDD12P-EG2-WE is a wireless dual-tech detector covering 12m.
What does anti-masking mean on a motion detector?
Anti-masking lets a detector report when someone covers or obstructs it to blind it before a break-in. Models with it include the Aritech VE735AM with multi-channel anti-masking, the Texecom AKE-0001 Capture dual tech rated EN50131-2-4 Grade 3, the Optex VXI-AM outdoor detector and the Ajax 117717.09.WH1 Superior MotionProtect G3 Fibra.
Can I use a motion detector in a house with pets?
Yes, with a pet-immune detector set up as its maker describes. The Pyronix KX10DTP3 is pet-tolerant up to about 24kg, the Ajax 44404.09.BL1 MotionProtect Fibra and 22934.23.BL1 MotionCam ignore pets when installed and configured correctly, and the Texecom GDC-0006 Capture D20-W has an optional PetWise mode to reduce false alarms.
When should I use a ceiling-mounted motion detector?
When a room is better covered from the centre rather than a corner, or when the walls leave no good mounting point. The Pyronix OCTOPUSDQ is a wired quad PIR with 360° coverage to 12m at 12V DC, the Texecom AKF-0006 Capture CQ covers 9.3m at 360°, and the Texecom Capture CD-W (GDE-0001, GDE-0006) adds a microwave sensor.
Which motion detectors can be used outdoors?
Detectors built for outside use, in weatherproof housings. The Optex VXI-AM is IP55 rated with dual PIRs and covers up to 12m, the Texecom AFQ-0001 Premier External TD is IP65 sealed, the Hikvision DS-PDTT15AM-LM-WE is an IP65 tri-tech wireless detector, and the GJD022 ELITE covers 10 to 35m for alarm and lighting control.
What is a motion detector with photo verification?
A detector with a built-in camera that takes photos when it triggers, so an alarm can be checked before anyone responds. Ajax MotionCam Jeweller models such as the 36490.120.BL1 take photos on alarm and on demand, the 53771.169.WH1 Superior MotionCam Fibra is a wired version, and the 36662.121.WH1 MotionCam Outdoor is IP56 rated for outside.
Can a motion detector trigger CCTV cameras?
Yes, external perimeter detectors are made for it. The GJD230 D-TECT 2 IP runs on PoE with a beam range programmable up to 30m and integrates directly with major VMS and camera systems, the GJD260 D-TECT 3 IP is a PoE dual-tech version, and the GJD300D D-TECT 2 has outputs that can control cameras, alarm panels and GJD lighting controllers.
Is there a motion detector for a long corridor?
Yes, the Texecom Capture LR50 is a 50m long-range corridor PIR for hallways and other long, narrow spaces, with a quad element pyro sensor; it is listed here as the AKW-0001 and GDF-0001. For wide open areas, the Texecom AKE-0001 covers 20m at 85°, and the GJD310 D-TECT 3 detects to a programmable 30m outdoors.
Do wireless alarm sensors work with any alarm panel?
No, a wireless detector has to use the same radio protocol as the panel. Ajax Jeweller detectors pair with Ajax hubs, Texecom Ricochet detectors such as the GBW-0002 Premier External TD-W join a Ricochet mesh, and the Hikvision DS-PDD12P-EG2-WE is an AX Pro series detector, while the GJD660 D-TECT Universal is made to integrate with third-party wireless modules.
