The wireless SLV Control outdoor motion sensor can be placed everywhere outdoors and indoors, without wiring or high voltage connection, because the transmitter is battery powered. When motion is detected, the wireless motion sensor automatically activates one or more SLV Control receivers. After a little while, the light or device connected to the receiver is automatically turned off again. This switch-off delay is programmable (from 5 seconds to 1, 5, 10 minutes). The maximum detection range is 6 meters. Perfect for your toilet, bathroom, hallway, passage, walk-in closet or storage closet. The motion sensor is compatible with the SLV Control receiver with the automatic code system. This transmitter sends radio signals at 433.92 Mhz. The signal passes through walls, windows and doors, with an indoor range of up to 30 meters.
