Stop Arm Camera 2: Installation

The Stop Arm Camera 2 supports school transportation safety by automatically recognizing, capturing, and storing evidence of vehicles passing a bus that has enabled its stop arm.

Camera Views

The camera will capture three recordings for each stop arm violation.

1. A wide-angle view showing the entire pass, this view will capture the stop arm deployment.
   
2. A rearward facing view to capture the license plates of vehicles with high detail.
   
3. A forward facing view to capture the license plates of vehicles with high detail.
   

Mounting the Camera

The camera should be mounted parallel to the road, on the driver's side of the bus, with the stop arm partially in (but not obstructing) the view from the wide-angle camera lens. The recommended mounting area (highlighted in the image below) is 6”-18” below the bottom of the stop sign and 12”- 60” forward from the center of the open stop arm.

1. Select the area for installation and stick the included mounting sticker template on the bus panel.
   
2. Verify that there is proper clearance behind the selected mounting location to avoid potential damage.
3. Use a center punch to create the (5) pilot holes marked on the template mounting sticker. 
4. Use a 3/32-inch bit to drill the four (4) "camera mounting holes" on the mounting sticker. 
5. Use a a 7/8-inch hole saw or step drill to drill the center "camera cable hole" on the mounting sticker. 
6. Remove the mounting sticker template from the bus.  
    
7. Run the Ethernet cable through the center cable hole and hold the camera against the bus panel.
   • Use a wire fish tool to guide the cables in if needed.
      
8. Verify the camera is accurately placed for mounting:
   • The rubber mounting gasket should be aligned with the camera and the front lens should be above the "P" Pro-Vision logo.
   • If there is any confusion about this, compare the placement to the Stop Arm Camera image above or in the wiring diagram below.
     
9. Use the four (4) included screws to mount the Stop Arm Camera 2 to the bus panel. 
   
10. Remove all protective films covering the camera lenses and infrared LEDs. 

Connecting the Wires

1. Route the included 15 ft Ethernet cable; the yellow-tinted side must be routed towards the DVR and the side with the plastic gasket towards the camera cable hole. 
   • The plastic gasket on the extension cable will create a water resistant seal with the Ethernet connection on the Stop Arm Camera. This must be routed and installed correctly to avoid wire damage.
   • When coiling excess cable, the minimum coil diameter to avoid wire damage should be 6 in. 
   • Do not over-tighten any cable ties when securing wires. 
     
     
     
2. Plug the yellow-tinted side of the Ethernet extension to the included passive PoE cable assembly which splits into an Ethernet cable and a four (4) pin connector.
    
3. Plug the Ethernet (RJ-45) connector into the back of the DVR.
4. Plug the four (4) pin connector into the "SD Out" connector on the back of the DVR. 
   
   
5. Plug the camera side of the extension cable (with waterproof cover) into the camera Ethernet (RJ-45) connection. 
   
   
   
   
6. Secure the extension's waterproof cover over the camera's Ethernet connection to create a water resistant seal. 
   • Loosen the rear portion of the waterproof cover to allow it to slide down the cable.
   • Slide the black cover over the connection. 
   • Rotate the cover clockwise 1/4 turn to secure it in place. Ensure the red o-ring is in place. (as shown below).
   • Retighten the rear portion of the waterproof cover to ensure the rubber seal around the cable is water tight.
     
     

Trigger Connection

The camera's red trigger wire must be connect to the bus's stop arm activation wire.

• Locate the signal wire that has 12Vdc running through it when the stop arm is activated. Use some red extension wire if needed. 
• This wire may be found in several locations. It is most commonly found in the harness going to the stop arm on the driver's side of the bus. Typically, the harness can be followed to the outside power distribution area, the bus wire channel running from the front driver side to the rear of the bus, or the air solenoid which activates some stop arms.
• If upgrading from the previous Dual-Lens Stop Arm Camera model, the trigger wire should have already been located and ran to the DVR, remove the trigger wire from the DVR and connect it to the new camera's trigger wire.

Testing Camera Operation

Test the camera to confirm it is properly operational.

• If installing the camera as part of a new DVR installation, follow Stop Arm Camera 2: Post-Install Testing for detailed instructions.
• If adding the camera to an existing DVR system , follow Stop Arm Camera 2: Retrofit Post-Install Testing for detailed instructions.
