The VD-3/5/7/8/9000 range mount on the inside of the front windscreen using a flat plastic glass plate mount (like and etag mount).
The mount is secure and the recorder simply slides into the mount allowing ease of removal or installation into other vehicles (additional glass plate mounts are required).
These recorders sit no more than 30mm from the surface of the glass.
We do have suction cup mounts as an option for those that often between vehicles.
VD-1500 and VD-1600 recorders mounts contain the GPS antenna and you can still remove the recorder from the mount via a rotation lock and disconnection of the antenna cable.
