Motion sensors with dual detection
The detector combines PIR and microwave, making it especially stable in rooms where regular PIR sensors can struggle. It only reacts to real movement and is therefore ideal in areas with temperature fluctuations, sunlight, ventilation or wood-burning stoves. The detector covers a wide area and can be used in living rooms, hallways, offices, workshops and other larger rooms where you want reliable detection.
Dual-Tech detection – fewer false alarms
The detector uses both PIR and microwave to detect movement. Both technologies must confirm activity before the alarm is triggered. That means far fewer false alarms, especially in rooms where temperatures can vary, or where there is sunlight, ventilation or small animals.
Stable monitoring in many room types
This sensor is suitable for rooms where a standard PIR can be challenged: living rooms with a wood-burning stove, garages, workshops, large window areas, offices or places where heat and cold change quickly. The Dual-Tech design makes it more stable and reliable in these environments.
Wide coverage and high sensitivity
The detector monitors a large area and registers movement quickly and accurately. It's therefore ideal in larger rooms or passage areas where you want early and secure detection.
Pet immunity for smaller pets
The detector can ignore smaller pets, so a cat or small dog won't trigger unnecessary alarms. That gives more peace of mind if you have animals at home. However, we always recommend placing magnets on the doors and windows in rooms where the pets are, as a motion sensor can never be 100% foolproof against animals.
Easy installation in the AX Pro system
The detector is added wirelessly via the AX Pro app and is quick to mount. It can be fixed to the wall at an appropriate height, and the app guides you through the setup.
Long battery life and maintenance-free operation
The detector uses a powerful battery that typically lasts for several years. The system notifies you well in advance when it needs replacing, so you won't suddenly be without protection.
