PIR and Microwave Motion Detectors
Motion PIR and microwave detectors use a combination of passive infrared and microwave detection technologies to provide strong catch performance for alarm systems. These dual technology sensors are commonly used where reliable movement detection and reduced false alarms are important.
CTC Communications supplies PIR, microwave and dual technology motion detectors from trusted brands including Bosch, Dahua, Hikvision and Hills, with options suitable for homes, offices, retail spaces and commercial security installations.
PIR and microwave motion detectors are alarm sensors designed to detect movement within a protected area. PIR detection identifies changes in infrared heat, while microwave detection uses microwave signals to detect movement. When combined in a dual technology detector, both technologies can help improve reliability and reduce nuisance alarms.
Detects changes in body heat and movement within the sensor’s coverage area.
Uses microwave technology to help confirm movement in protected areas.
Combines detection methods to improve catch performance and reduce false alarms.
Connects to compatible alarm systems as part of a wired or wireless security setup.
Dual technology motion detectors are often selected for areas where accuracy matters. Because the detector uses both PIR and microwave sensing, it can provide stronger performance in challenging environments compared with basic motion sensors.
Designed to detect intruder movement reliably within the protected area.
Dual technology can help reduce nuisance alarms when installed correctly.
A practical option when replacing older alarm sensors or improving coverage.
Used in homes, offices, shops, warehouses and commercial alarm installations.
Tritech motion detectors and selected pet-friendly motion sensors are designed to allow movement from pets within the home while the alarm system is active, helping reduce unwanted alarm activations.
Pet-friendly performance depends on the detector model, pet size, mounting height, room layout and installation position. For best results, choose a detector that suits your alarm system and have it positioned correctly.
Selected models are designed to reduce alarms caused by pets moving through protected areas.
Combines detection technologies for improved accuracy and dependable alarm performance.
Mounting height and sensor angle can affect pet tolerance and detection performance.
Ideal for households that need internal motion detection while considering pet movement.
Shop PIR, microwave and dual technology motion detectors from trusted alarm and security brands.
PIR and microwave motion detectors are used across residential and commercial alarm systems where dependable internal detection is required.
The best detector depends on your alarm panel, wiring, coverage area, pet activity and the type of security protection required. If replacing an existing detector, check the brand, model, wiring and compatibility before ordering.
Make sure the detector suits your alarm panel, receiver or wireless alarm system.
Choose a detector with the right detection range for the room or protected space.
Select a pet-friendly model if pets move through the area while the system is armed.
Correct installation helps maximise detection and minimise unwanted alarms.
