The Streetwise NightWatcher SWNW720 uses patented robotic lighting technology to protect your property by causing a super-bright security light to lock on and follow an intruder. This model also features a high definition security camera that starts recording whenever motion is detected. Traditional motion activated lights just turn on when motion is detected; the NightWatcher’s Robotic Light will lock on and follow an intruder’s motion while the high definition security camera captures photos or video evidence of the intruder.
