The NOVOFLEX Suction Cup With Ball Head is designed for mounting a camera over any flat plane surface, like a sheet of glass. The suction cup attaches directly and securely to the surface. The ball head is mounted on the suction cup's 1/4" thread screw, and a camera (up to 6.6 lbs (3 kg) in weight) can be mounted on the ball head, giving you maximum flexibility in placing and aiming the camera.
