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 and Optex.

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

How do pet-friendly alarm sensors work?

Pet-friendly alarm sensors, often called pet-immune detectors, are designed to ignore the heat and movement of a small animal while still detecting a person. They usually do this through a tuned lens pattern and signal processing that respond to a larger body. Check the pet weight rating, and keep furniture that pets can climb on away from the detector's view.

How do motion sensors connect to a burglar alarm panel?

Motion sensors connect to a burglar alarm panel as detection zones, either by cable or by radio to a compatible wireless receiver or hub. When the system is set and a sensor detects movement, the panel triggers the alarm. Wired sensors can use separate zone wiring or a shared data bus. Wireless sensors usually need the same radio protocol as the panel, so check compatibility first.

What is an alarm sensor?

An alarm sensor is a detector that signals the alarm panel when it senses a sign of intrusion, such as a person moving through a protected room. Many use a passive infrared element, and dual-technology models add microwave to confirm a detection. Wall, ceiling, curtain and outdoor versions suit different spaces. The range here includes wired and wireless motion detectors.
