This compact PIR motion detector from Axis uses passive infrared technology to detect movement at a distance of up to 12m (when mounted at a height of 1.5m – 2.4m) - even in darkness.

By delivering high levels of accuracy and reducing the number of false alarms, PIR motion detection offers a suitable alternative to camera-based motion detection - which can sometimes be less reliable if lighting conditions are challenging.

The unit can be easily connected and powered through any Axis 12 V DC I/O port, meaning it is compatible with a wide selection of Axis IP cameras. It’s also supplied with a tripod thread bracket which makes it possible to install the PIR to a standard camera mount for precise alignment of the detector.
