Overview of the Axis T8331-E

This product is discontinued, an alternative model can be found on the Axis accessories page

Using passive infrared technology, this outdoor-ready PIR motion detector by Axis has the ability to detect movement at a distance of up to 15m when mounted at the optimum height (area dependent) - even in darkness.

PIR motion detection delivers high levels of accuracy and reduces the number of false alarms, making it a helpful alternative to camera-based motion detection which can often be less reliable in difficult lighting conditions.

Users can easily connect and power the unit through any Axis IP camera that features a 12 V DC I/O port. The IP66-rated PIR motion detector is suitable for external installation and is also supplied with a tripod thread bracket - making it possible to install the PIR to a standard camera mount for precise alignment of the detector.
