This is an advanced DVR with built-in night vision that is loaded with features and looks just like a passive infrared motion sensor designed to blend into your home or business. It records video in high definition 720p to the micro SD card (not included) and is powered by AC power so you don't have to continuously recharge it. It has night vision so it can record in the dark and also has a motion detector to record when there is movement with a pre-motion trigger which will save the three seconds before the motion starts and the three seconds after the motion has stopped. This unit comes with the DVR, a remote control, AV cables (for viewing the picture directly on a TV or recording to a VCR or DVR), USB cable (for downloading video on your computer), and mounting hardware. It requires an SD card (not included).
