Overview
An electronic motion detector contains a motion sensor that transforms the detection of motion into an electric signal. This can be achieved by measuring optical changes in the field of view. Most motion detectors can detect up to 15 – 25 meters (50–80ft).
A motion detector may be connected to a burglar alarm that is used to alert the home owner or security service after it detects motion. Such a detector may also trigger a red light camera. Motion detectors have found great application in domestic and commercial applications. Some of these applications include motion-activated outdoor lighting systems, motion sensor street lamps and motion sensor lanterns.
