Wireless motion detector for indoor use in white color Universal wireless extension for your doorbell. Detects movements and triggers a doorbell signal at connected doorbell receivers via radio. Both the activation threshold (brightness) and activation duration can be set. If movement is detected in the sensor's detection area, the wireless motion detector switches one or more connected CUVEO receivers ON for the selected time and then OFF again. If motion is detected by the sensor again within this set time, the timer starts again.
