This P.I.R. motion detector is for interior protection. It detects object movement having a human body temperature. The JS-20 distinguishes itself with excellent RF immunity.

This P.I.R. motion detector is used to protect interiors. The signal from the sensor is electronically analyzed. This ensures that the detector provides excellent sensitivity and at the same time false alarms are basically eliminated.

The detection analysis rate can be adjusted to increase its immunity if the JS-20 is installed in a problematic location. The JS-20 distinguishes itself with excellent RF immunity. It can be mounted on a flat wall or in a corner.
