HD Stop-Arm Camera Details/Installation

HD Stop-Arm Camera


The HD Dual-Lens Stop-Arm Camera (Kit P/N: DVR-824 Camera P/N: PC-1824) is designed to capture license plates and faces of drivers that pass a school bus while the bus is stopped and has its flashing red lights and stop-arm open. The camera is waterproof (IP-67 rated) and has two (2) lenses with low-light image sensors set at 45° angles to the side of the bus that can provide 180° of coverage on the roadside of the bus. The camera is designed to be mounted directly to the bus, parallel to the road with four (4) self-drilling Phillips head screws. The camera also has a waterproof microphone for audio capture.

Stop-Arm Camera Installation

Mounting Locations:

The camera must be mounted parallel to the road surface on the driver’s side of the bus. The very bottom of the open stop-arm should be visible in the camera field-of-view, but not so much as to obstruct vehicle license plate capture. The flashing lights on the stop sign should not be in the camera view as they can affect the triggering function.

******On most bus models, mounting in the area forward of the stop-arm provides better wire routing to the DVR. Installation considerations - best placement, what to avoid, etc. - should include wiring and any reinforced metal areas so placement of components allows for optimal performance and view without damaging existing vehicle systems or operating parts.******

The camera must be orientated such that the two (2) 4 mm socket head bolts screw in from the bottom and the “PV” logo is upright, facing toward the center of the road. The proper orientation of the mounting bracket and camera are marked with “UP“.

IMPORTANT! For the first installation of each different vehicle model variation, it is recommended to temporarily connect the camera, without the mounting base assembly attached to the recording unit. Power the system on and then hold the camera in the desired mounting location to observe the view to confirm it is satisfactory before continuing.


  1. Attach the camera mounting base to the rubber mounting gasket as shown to the right. Hold the mounting base assembly to the desired mounting location and ensure the base is parallel to the body lines on the side of the bus. Mark the center of the four (4) camera base mounting screw locations (shown in ORANGE) and the large center cable hole (shown in RED).
  2. Place the camera mounting base assembly aside and then verify that there is clearance behind the four (4) marked mounting screw locations, as well as clearance and access to behind the one (1) large, marked cable hole location.
  3. Drill a 1/2” diameter hole in the center marked location (shown in RED above). DO NOT DRILL THE OTHER HOLES.
  4. Using the female end of the camera connection or extension cable, verify there is enough clearance for the connector to fit through the hole and route toward the recording unit. If needed, drill the 1/2" hole out to 3/4" to allow the connector to route into the vehicle body.
  5. If certain of the camera’s mounting location and that the correct hole for the cable has been drilled, place the mounting base assembly so that the four (4) ORANGE marks completed in Step 1 are showing. Orient the mounting base assembly so that the bolt cutouts in the base and gasket point toward the ground and the “UP“ arrow points toward the roof of the bus. Use the four (4) self-drilling screws provided to attach the base and gasket to the side of the bus.
  6. After the base and gasket are securely attached to the bus, route the camera cable through the drilled center cable hole and place the camera in the mounting base assembly. Orient the camera so that the bolt cutouts in the housing are pointed toward the ground and the “UP“ arrow points toward the roof of the bus as shown to right.
  7. Slide the two (2) 4 mm bolts into the bottom of the camera connecting the camera housing to the mounting base assembly. Using the provided 3 mm ball end Allen wrench, tighten the bolts into the Nyloc nuts that are attached to the bottom of the housing. The bolts should be nearly flush with the rubber gasket when fully tightened.
  8. Connect the camera cable to the extension cable running to the DVR, and then connect the extension cable to the “Camera 7” port on the DVR unit for the camera to be recognized.
