INSTALLATION
These instructions do not apply to all vehicles. They are only meant as a general
guide due to the number of different makes & models. For vehicle specific
questions contact your vehicle’s manufacturer.
Camera installation
There are several ways to mount the camera on the back of your car. But the most
convenient is to mount it near the license plate of the car. Supplied is one mounting plate
that can be fixed behind the license plate, and the mounting plate have been installed in
the camera.
The camera is tiltable, camera angle can be adjusted manually on vertical direction.Make
sure that its field of view and detection are not obstructed.
At some type of cars it is not possible to mount the camera near the license plate. You
may have to find another spot at the back of your car to mount the camera.
1. Remove the rear license plate, and then loosen the license plate bolts/screws.
2. Position the supplied mounting plates (with camera together) behind the license plate
bracket. Secure both license plate bracket and mounting plates with the license plate
bracket bolts/screws.

3. Mount the license plate on the license plate bracket.
4. Choose a routing path for the camera’s power cable through the vehicle’s body to the
reverse light circuit. If in doubt, seek professional installation assistance.
5. Some vehicles may have a hole available to pass the wire through, such as where the
license plate light is mounted, or you can drill a hole close to where the power cable
is attached to the camera. Once you have chosen where the cable will enter the
vehicle’s body, remove the camera. If you are able to use an existing opening, skip
the next two steps.
6. Before you drill a hole you MUST CHECK and see WHAT IS BEHIND WHERE YOU ARE
DRILLING. If there are any vehicle components, such as electrical parts or fuel
system components behind where you are drilling, you must take whatever
precaution is necessary not to damage them. Remove the license plate and camera
before drilling.
7. After you have drilled the hole, insert the supplied grommet, then pass the camera
cables through the grommet into the vehicle. You must use the grommet to prevent
the metal edge of the hole from cutting the camera cable.
8. Next you’ll need to find the vehicle’s reverse lights. Turn the vehicle’s ignition key to
the accessory position, engage the parking brake and put the car in reverse. Look at
the vehicle’s tail lights to see where the reverse lights are located, they are the white
lights. To locate the reverse light’s 12 / 24 V+ wire it will be necessary to gain access
to the rear of the vehicle’s tail light. For help locating the vehicle’s reverse light circuit
contact your vehicle’s manufacturer for vehicle specific wiring diagrams.
9. Once you have located the reverse light circuit you will have to route the camera
cable to that location. You must securely fasten the power cable to prevent it from
being caught on any vehicle component such as the trunk hinge. Never route the
cable on the outside of the vehicle!
10. The reverse light sockets on most vehicles
have two wires connected to them.
Usually the negative wire is black and the
positive wire is a colored wire. If you are
uncertain about the wiring, you can use a
12 / 24 volt multimeter available at most
auto parts stores to determine which is
the positive wire. Follow the
manufacturer’s instructions for the safe
use of the multimeter.
11. After determining which wire is the
positive and which is the negative, turn
off the ignition key, then remove the battery’s negative cable.
12. Splice the red wire using the supplied in-line wire connectors to the reverse light’s
positive (+) wire. Use a set of slip joint pliers to squeeze the TAP and insure good
connection.

13. Next splice the black wire of the camera power cable to the reverse light’s negative (-)
wire or ground.
14. Replace the reverse light bulb, and then re-install the light socket. Secure all the
wires with cable ties or electrical tape.
15. Re-attach the negative battery cable to the battery.
Monitor Installation
When choosing a location to mount the monitor, make sure the
monitor is in an area that will not obstruct your vision while driving.
1. Before mounting the monitor, clean the mounting surface well.
2. Position the suction mount to the smooth surface which suits
your requirement.
3. Press the suction cap against the smooth surface and press the
lock down to attach and fix the mount to the surface.
Snap in the monitor to the suction mount.
4. Adjust the mounting arms to suit your view angle to the monitor and tighten the
screws on the mount to fix the position.
5. Route the power cable to the vehicle’s cigarette lighter socket/12/24V power outlet.
The cable must not interfere with the safe operation of the vehicle.
6. Insert the small 12 / 24Volt DC plug of the power cable into the right side of the
monitor.
7. Plug the 12 / 24 Volt cigarette lighter plug into the vehicle’s cigarette lighter socket.
To maximize the effectiveness of the suction mount, it is recommended that the
application be performed under the following conditions:
•Surface temperature should be between 21 and 38 degrees Celsius.
•Application below 10 degrees should be avoided.
•Application should not occur in direct sunlight.
Mounting should be protected from exposure to direct sunlight for a period of 24 hours.
NOTE: UNDER EXTREME BRIGHT LIGHT CONDITIONS, THE SCREEN IMAGE MAY TAKE A
FEW SECONDS TO STABLIZE. PLEASE WAIT UNTIL THE IMAGE HAS STABLIZED BEFORE
BACKING UP.
System testing
1. Reattach the vehicle’s negative battery cable.
2. Turn the ignition key to the accessory position, do not start the vehicle.
3. Engage the parking brake, and then put the shifter in the reverse position.
4. After testing the unit and you are satisfied with the route you have chosen for the
cabling, you must permanently install it.
5. Route all wires behind interior panels or under carpeting so they are hidden. Use
supplied cable ties to neatly gather any excess wire.
