This all-in-one motion detector, color camera, and digital recorder covers an approximate 40ft.x 40ft. area but looks like a standard PIR security motion detector. It records on a SD media card (up to 2 gig not included) that can easily be removed and played back in Windows Media Player with no special software needed in your existing PC. Your PC must have a built-in SD card reader or you can use a USB type card reader that is readily available. You can also plug in the included video cable to a standard television to review the files. The high resolution camera also includes night vision for recording in dark conditions. The key chain size wireless remote allows you to activate and deactivate the recorder so it only records when you are away from the protected 40 x 40 foot area.This device is for indoor use only.
