CEILING LUMINAIRE P -SARJA RS PRO LED P2EM FLAT S 3K IP54

High-frequency or radar sensors (HF) are suitable only for indoor motion detection. HF sensors detect both perpendicular and transverse motion equally effectively, making the technology well suited for corridor and lobby motion detection. The high-frequency signal penetrates lightweight wall materials. This property can be utilized, for example, in monitoring different areas of public restrooms, but it may also cause "false triggers" from behind lightweight partition walls. Warm air currents generated by heaters in storage rooms and data centers do not cause false triggers for HF detection.
