The MD-300 is a rugged passive infrared motion detector well suited for use in harsh outdoor and indoor applications where water, dust, physical shock and temperature extremes are expected.

The detector uses a dual pyroelectric sensor with jumper selectable one or two zone detection. It employs a sequence processor that combines bidirectional pulse counting and motion verification, sophisticated signal processing, and a unique Fresnel lens that focuses the invisible IR energy on the sensor while blocking stray or reflected light. Unlike in-video motion detection, which requires adequate and constant light, the MD-300 can operate in total darkness.

Housed in a heavy-duty cast metal housing, the unit is dustproof and water-resistant with accommodation for bottom or side conduit entry.
