The camera portion of the kit is a small circular disk that is roughly 2 inches in diameter. The unit clips into a metal base and is powered by a Micro USB cable that is included with the kit. There are 12 IR LEDs around the camera lens to illuminate the area for the night vision operation.
The camera and the base are two separate pieces. To assemble slide the camera into the base until it snaps into place. The base articulates 180° to allow the camera to be mounted to the wall using the supplied mounting plate and screws. Just screw the mounting plate to the wall and snap the base into the plate.
