Ours has been designed to better fit all the 5MP cameras we sell, and includes a small interior lip to prevent the camera from sliding. The mount is made to attach to the inside of the lid with 3M double-sided VHB tape, and the camera angle is easily adjusted by loosening the knobs on either side of the mount, and the face plate is held in place by tension clips.
The mount includes the two bolts and hex nuts needed to set the angle, and a pair of VHB pads for mounting. Units are shipped assembled.
