Over the last 30 years, our mobile video digital recorders have been adopted by many companies for their application
on industrial trucks, pallet trucks, and a wide variety of other vehicle-mounted mobile camera applications.

One of the most interesting of those applications has been in what we refer to as the “Switcher Truck 5th Wheel King Pin Camera System”, also called Yard Mules, used by companies who handle and move large numbers of containers/trailers on their yards.

The Switcher Truck 5th Wheel, King Pin Camera is the adaptation of our existing Mobile Vehicle Surveillance & Security Cameras adaptation of our School Bus Video Camera system wherein it is used to monitor the locked or not locked status of the 5th wheel or King Pin jaws in the yard tractor-trailer swapping or switching operations. Often what appears to be a good lock is not, and in some cases, where King Pin appears lock sitting still, the jaws can open and lose a load while making a turn in the yard.
