Abstract: A vehicle door or window supported camera mounting bracket assembly including a pair of L shaped nesting grips having depending, cooperating, plastic coated clamp legs embracing a vehicle window top, door, door portion, or the like. An otherwise conventional camera mount is journaled through an outer end of the upper grip and a cooperating pin and slot construction together with a set screw threaded into the upper grip through the slot, formed through the lower grip, permits sliding adjustment of the grips relative to one another and thus spacing of the clamp legs, from close together (e.g., one quarter inch or less) to engage a vehicle window, to relatively far apart (e.g., two inches or more), to engage a vehicle door portion or door. The set screw is then tightened to secure the clamp legs tightly against a vehicle window or door.
