This is the weatherproof video recording security light that is powered by sunlight, allowing it to be mounted where electrical power isn't accessible. When its motion sensor detects movement from up to 40' away day or night, it begins recording video across a 110º angle to track the comings and goings of those who pass beneath. Its 16 LEDs bathe the area in 879 lumens of bright white light and can be set to stay on 10-60 seconds after motion ceases. The included 16 GB microSD card stores four hours of time-stamped video and the camera (or microSD card) plugs into a PC’s USB port to access videos. The unit’s rechargeable batteries provide 110 minutes of continuous use and are recharged via the solar panel. LEDs are rated for 30,000 hours. For Windows XP and higher. 10" H x 8 1/4" W x 9" D.
