Alpha IP Motion Detector interior


The Alpha IP Motion Detector with Brightness Sensor is designed especially for indoor application. The device detects movements as well as light intensity with an integrated brightness sensor.

This high performance motion detector can be used for security appli- cations and light control. In connection with other Alpha IP devices an alarm can be triggered or light activated if motions are detected. Thanks to the detection distance of up to 12 meters and a detection angle of 105 degrees (approx.) as well as different mounting possibili- ties the detection range can be optimized to the particular surround- ings. The motion detector can be placed anywhere on a wall, in a corner or in the supplied stand.

Brief changes in the level of brightness are filtered out. Thus, unin- tended response of the motion detector can be avoided. The bright- ness level for triggering and the level of sensitivity can be flexibly adjusted.

Thanks to the integrated tamper contact, the app is immediately in- formed about unauthorized removal or manipulation of the motion detector.
