Detects human presence by temperature difference with background thermal radiation. The microwave sensor prevents false alarms caused by complex interference.
Designed for operation in rooms with fireplaces and air conditioners. Detects and ignores draughts, movement of curtains and blinds, and light flickering, glare and reflections.
Ready to operate straight out the box. The battery is already installed inside, therefore there is no need to disassemble the detector. It can be mounted in just a few minutes using the SmartBracket mount.
