Motion Detectors for Alarm Systems

Motion Detectors for Home and Business Security Alarm Systems

A motion detector is a sensor connected to a security alarm system that helps detect movement inside a protected area. When triggered, it can alert the homeowner, business owner or monitoring service to possible intruder activity.

CTC Communications supplies wired and wireless motion detectors for homes, apartments, offices, retail spaces and commercial properties, including pet-friendly options, standard PIR detectors, dual technology sensors and detectors compatible with leading alarm brands.

What Does a Motion Detector Do?

Motion detectors are designed to detect movement within a room, hallway, office, warehouse or protected area. When your alarm system is armed, a triggered motion detector can activate the alarm, sound sirens, send app notifications or report to a monitoring service depending on your system setup.

Intruder Detection

Detects movement inside protected areas when the alarm system is armed.

Home and Business Use

Suitable for homes, shops, offices, warehouses and commercial spaces.

System Integration

Connects to compatible alarm panels through wired or wireless technology.

Alarm Alerts

Can trigger sirens, app alerts, event logs or back-to-base alarm monitoring.

Wired, Wireless and Pet-Friendly Motion Detectors

Motion detectors can connect to an alarm control panel by hard wire or through wireless connectivity using a compatible wireless receiver or hub. Wired detectors are commonly used in professional alarm installations, while wireless detectors are useful for existing homes, apartments and areas where running cable may not be practical.

Tritech motion detectors and selected pet-friendly motion sensors are designed to reduce false alarms caused by pets moving around the home while the alarm system is active. Pet tolerance varies by detector model, pet size, mounting height and room layout.

Wired Detectors

Reliable option for professionally installed alarm systems and long-term performance.

Wireless Detectors

Ideal for homes, apartments and properties where new cabling is difficult.

Pet-Friendly Detectors

Designed to help reduce nuisance alarms caused by pets, when installed correctly.

Dual Technology Sensors

Some models combine detection technologies to improve accuracy and reduce false alarms.

Popular Motion Detector Brands

Choose from trusted motion detector brands commonly used in Australian alarm installations, upgrades and replacement work.

Where Are Motion Detectors Used?

Motion detectors are commonly installed in areas where intruder movement is likely after entry. Correct placement is important for reliable detection and to help reduce false alarms.

  • Entry areas and hallways
  • Living rooms and open-plan spaces
  • Offices and reception areas
  • Retail shops and stock rooms
  • Warehouses and commercial premises
  • Garages and internal access points
  • Holiday homes and investment properties
  • Areas requiring internal alarm coverage
Choosing the Right Motion Detector

The right motion detector depends on your alarm system brand, wiring, room layout, pet activity and the type of protection required. If you are replacing an existing detector, check the model number, alarm panel type and whether the device is wired or wireless before ordering.

Check Compatibility

Confirm the detector works with your alarm panel, receiver or wireless alarm hub.

Consider Pets

Choose a pet-friendly detector if pets move through the protected area while armed.

Review Detection Range

Match the detection range to the room size, mounting location and coverage needs.

Professional Installation

Correct positioning and setup help improve detection and reduce nuisance alarms.
