Camera Connection
oThe SVA055-CA is a dual road and driver camera.
NOTE: If not pre-cut, cut wire to convert driver camera to AHD (720p) and
connect to CH2 input of CP4.
Operation procedures:
1. Attach Windshield bracket to the H bracket using the two bracket screws
2. Clean the windshield area where the SVA055-CA will be mounted (the camera lenses
should be within the top 2” of the windshield wiper zone, and centered).
3. Remove the 3M adhesive backing and press firmly on the glass for 30 seconds.
4. Loosen and adjust the side screws on the H bracket to adjust the camera angles to
be parallel with the road.
5. Tighten the screws and connect the 4m extension cable.
6. Run the extension cable through the headliner, down the A pillar and connect the 4
pin connectors to the video inputs on the DVR.
7. Power up the DVR and confirm the SVA055 field of views are properly angled to
capture the road and driver. You can use the LCD monitor or the install wizard to
verify.

4. CP4 Power Cable and Wiring
Lay out the power cable roughly where it will run once hidden behind the vehicle's interior panels. This
gives you an idea of where to route the cable and how much slack to leave on the way down to the
vehicle’s power source.
Secure the power cable extension into the headliner and down the A-Pillar. Route the power cable
around the side and behind the rest of the interior panels down towards the fuse box / power source.
Make sure the vehicle is off, then connect the required wires to the vehicle, as shown below in the
wiring diagram.
Power Connection
Video Output Cable & I/O Harness (optional)
