Old SV rear vision camera they also used in bus video systems.

With few exceptions, the low-cost school bus camera system equipment that is offered and installed nationwide across the USA for the documentation of events and activities and surveillance of students in their school bus transports is very similar to the system equipment that is installed in a wide variety of other vehicle video camera applications.

The cameras used in these varied applications are the primary equipment difference in these systems.

For example, the primary differences in the Forklift HD Industrial Lift Truck Hi Reach Order Picker Operator Safety Camera Systems are the FCAMs, which are small teardrop cameras in metal cases with extremely wide-angle lenses. Because of the close proximity of the environment they operate in, the trade-off between FOV (Field of View) and DOF (Depth of Field) is a welcome one.

When it comes to School Bus Stop Arm Cameras, we see the same change in camera design to achieve the primary function of an external camera: recording vehicles passing a stopped bus while students are loading or unloading. These SAC, aka Stop Arm Cameras, must be waterproof to at least IP67, and the standard wide-angle lenses are replaced with a tight telephoto lens of 12 mm to zoom in on the license plates of the vehicles that may be passing them.

In the case of Warehouse Terminal 5th Wheel King Pin Trailer Swapping Yard Mule Camera systems, the high "G" impact of the 5th wheel locking and unlocking operation requires a waterproof camera with all internal components and boards sealed in resin to prevent damage during the high "G" impacts in that environment.
