The boom box plugs into the wall to power the boom box, DVR and the camera. This hidden camera features motion-activated recording that starts as soon as motion is detected. With motion-activation, you won't have to fast forward through hours of uneventful recording. Also has Motion Detection Area Masking. For example, if you have a dog or cat and don't want it to set off the motion detector, you can mask the lower quarter of the field of vision so it does not detect motion. You can view your recordings by using the included RCA cable to connect to your TV or computer or insert the included 8GB SD card into your computer. Color Camera With Built-In DVR.
