Axis T8331 is a passive infrared motion detector for enabling motion-based surveillance. In some scenarios, it can be hard for the camera to detect motion. By using passive infrared (PIR), T8331 provides excellent motion detection in any lighting condition with fewer false alarms. The detector thus saves on bandwidth and storage, because you're only recording what you need to record. T8331 is designed for indoor installation on a wall or on an Axis camera using the included tripod thread bracket. It has a maximum range of 12m (40ft).
