4) Using a 3/16-inch (5 mm) drill bit, drill the mounting holes. 5) Connect the video and power cables to the camera assembly. 6) Mount the camera assembly to the vehicle surface using two fasteners screwed into panel nuts. See Figure 7 or 8 (depending on the type of camera assembly being installed). Figure 7. Angled flush-mount housing installation Figure 8. Square flush-mount housing installation 7) Refer to section 2.4.3 Adjusting Cameras for Functional Field of View to align the camera’s field of view according to the appropriate angle. 8) Attach the cover plate to the housing. If you are installing a square housing, you must drill two additional mounting holes for the cover plate. See Figure 9 or 10. 0150-0263A / May 2003 Hardware Installation BusSecure User Manual Figure 9. Angled flush-mount housing cover Figure 10. Square flush-mount housing cover 2.4.3 ADJUSTING CAMERAS FOR FUNCTIONAL FIELD OF VIEW Depending on location, the camera’s position might have to be adjusted to provide the best field of view. Adjusting the camera positioning might include altering the position of the camera and, for surface-mount cameras, using a spacer. To adjust the angle of the camera, see Figure 11 and perform the following: 1) Loosen the camera’s pivot screws. 2) Rotate the camera to the correct angle. 3) Retighten the pivot screws. Surface-mount cameras are configured at the factory to be installed onto the ceiling of the vehicle. If you are installing a surface-mount camera on the side of the vehicle, see Figure 12 and perform the following to rotate the camera lens: Figure 11. Adjusting the camera angle CAUTION Over-tightening the set and pivot screws can damage the camera’s lens. 1) Loosen the setscrew on the top of the camera assembly. 2) Rotate the camera assembly 90°. 3) Retighten the setscrew. Figure 12. Rotating the camera 0150-0263A / May 2003 BusSecure User Manual Hardware Installation To adjust the camera according to where it will be mounted on the vehicle, perform the following: 1) Figure 13 shows orientation of a camera for mounting on the curbside of the bus, the backside of the bus, or in a forward-facing position on the dashboard. Note that the lens set screw ( ) and the wiring harness ( ) are positioned at the top of the camera. 2) For cameras mounted on the streetside of the bus or surface-mounted facing backward, remove the two side-set screws, as shown in Figure 14, and lift the camera out of its bracket. 3) Rotate the entire camera assembly 180.. See Figure 14. 4) Insert the camera into the bracket, and replace set screws. The lens set screw and the wiring harness should now be positioned at the bottom of the camera. See Figure 15. Figure 13. Camera orientation for curbside mounting. Figure 14. Rotating the camera for street-side orientation Figure 15.

CAUTION Do not install the Impact Sensor until you have tested its functionality on each vehicle. The Impact Sensor should be mounted on a flat, stable surface and secured to the frame of the vehicle. The mounting surface must not be subject to vibrations. 1) Using the Impact Sensor as a template, mark the location of the two mounting holes. The Impact Sensor should be aligned so that it is square with the front and rear of the vehicle. See Figure 16. 2) Drill the mounting holes with an appropriate size drill bit. 3) Mount the Impact Sensor. 4) Route the provided cable to the DVR. Connections to the P1 terminal block on the DVR Rear Panel Assembly are as follows: N/C wire (green or white) to terminal 1, common wire (black) to terminal 2, positive wire (red) to terminal 18. Align square with the front and rear of the vehicle Align square with the sides of the vehicle Cable to DVR Rear Panel Assembly Figure 16.

Note: There are two versions of the panic button: one with a key reset and one without. See Figures 17 and 18. Figure 17. Panic button without key reset Figure 18. Panic button with key reset 1) Using the panic button as a template, mark the location of the two mounting holes. 2) Using a 6/32-inch drill bit, drill the mounting holes. 3) Using a 3/4-inch drill bit, drill a hole for the panic button’s wiring. 4) Splice a six-conductor 18 AWG cable to the panic button’s wiring. Note: The panic button with key reset (Figure 18) has six wires, and the panic button without key reset (Figure 17) has only five. The N/C and common wires are both yellow and are interchangeable. 5) Route the cable to the DVR. Connections to the P1 terminal of the DVR Rear Panel Assembly are as follows: N/C and...
