Stop Arm Camera 2: Installation

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

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 camera view. The recommended mounting area (highlighted in the image below) is 6”-18” below the bottom of the stop sign and 12”- 60” from the center of the open stop arm, forward or rearward.

Mounting the Camera

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. Using a center punch and a 3/32-inch bit, drill the four (4) holes labeled "Camera mounting holes" on the mounting sticker. 
4. Using a center punch and a 7/8-inch hole saw or step drill, drill the single center hole labeled "Camera cable hole" on the mounting sticker. 
5. Remove the mounting sticker template from the bus.  
6. Run the Ethernet cable through the center cable hole and hold the camera against the bus panel.
7. 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. 
8. Use the four (4) included screws to mount the Stop Arm Camera 2 to the bus panel. 
9. 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. Connect the camera's red trigger wire to the bus's stop arm activation wire.
   • To do this, locate the signal wire that only has 10 Vdc -32 Vdc running through it when the stop arm is activated.
   • This wire may be found in several locations. It is most commonly near the stop sign in 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 Stop Arm Camera model, remove the trigger wire from the DVR and connect it to the new camera's trigger wire. 
6. Plug the gasket side of the extension cable into the camera Ethernet (RJ-45) connection. 
   
   
   
   
7. Secure the extension's gasket over the camera's Ethernet connection to create an water resistant seal. 
   • Slide the black gasket over the connection. 
   • Slide the red ring over the gasket to the connection point (as shown below). 
   • Screw the back of gasket closed. 
   • Visually verify the water resistant seal created by the gasket. 

Please note that the Stop Arm Camera 2 operates out of the box—no unique DVR configurations are are required (as was the case for previous iterations of the camera).

• If upgrading from the previous Stop Arm Camera model, the user should reset the Stop Arm Camera page configurations on the Ranger DVR. To learn more about this, see Stop Arm Camera 2: Upgrading from the Dual-Lens Camera.
