Camera installation Before starting with mounting and removing cover
off your car, adjust the system to your car and try it out!
READ THE INSTRUCTION FIRST, BEFORE INSTALLING THE REARVIEW CAMERA!
Note: You may have to disable the rear bumper bar, the rear spotlight and/or the luggage
compartment cover of your car. Check this possibility before mounting the rearview
camera. Reason is to get the power supply of the rearview camera from the reverse light
(when you put in the reverse gear of your car). Then remove all necessary cover to get the
power supply of the rearview camera to the reverse light. If this is not possible for you,
than you have to hire professional staff for installing the camera.
You have to notice that cars are different and therefore the installation has to be
individually. This manual will give two examples how to position the camera
depending on the positioning of your license plate. You have to distinguish between
license plate fixed to your luggage compartment or your rear bumper bar. The best
position for installing the rearview camera will be the bracket of rearview camera behind
the license plate.
First step: Loosen the license plate bolt or screw
and then remove the license plate on the rear of your
car. Temporary mount the rearview camera on top of
the license plate.
Luggage compartment: Hold the license plate to the
position it will be mounted and check if the handle of
the luggage compartment will be still reachable. If
not, you have to mount the camera on the bottom of
the license plate.
Rear bumper bar: Hold the license plate to the
position it will be mounted and check if the license
plate would fit with the camera on it. If not, you have
to mount the camera on the bottom of the license
plate.
Note: It does not matter if the camera is installed on
the top or the bottom of the license plate. The video
can be flipped on the monitor.
Second step: When you have found the right position to mount the camera and
everything will be reachable like the handle than clean the space behind the license
plate with fat solvent. A clean surface is better for mounting the adhesive from the
bracket of the rearview camera.
Third step: The rearview camera is still temporary
mounted on the license plate. Peel of the backing
paper of the bracket. Reinstall the license plate to the
car. Now press the license plate on the edge where
the rearview camera is placed firm against the car.
The adhesive has to touch the car over the whole
length.

When done all the above mentioned steps, you have to proceed step by step with
the following instructions:
Engage the parking brake.
Locate the reversing lamp of your car.
Open the luggage compartment of your vehicle and remove the coverage of the
reversing lamp (like you want to change a bulb, maybe a special tool is needed).
Remove the reversing bulb, to prevent damaging the bulb.
Forth step: Loosen the license plate again without
loosen the rearview camera. Drill one hole for the
power cable nearby the camera and behind the
incense plate location. If your car has an existing
hole, you can skip this step.
Attention: To not damage internal cable. The hole
for the power cable should be about 11-12mm.
Now it is possible to drill to more holes to secure the
rearview camera with screws. The drilled holes
should be a little bit smaller than the screws.
Depending on the thickness of the material use the
corresponding screws.
Fifth step: Put the power wire through the drilled
hole in to the car through the interstices of the car.
Reattach the license plate.
Note: In the wired mode, the user also needs to put
the connect cable through the car body to the wired
monitor.
Adjust the camera. You maybe have to adjust again
after you have powered the system.
Sixth step: You got the power supply
cable of the rearview camera to the rear
spotlight.
Use a voltage detector to find the power
supply of the rear spotlight for the reverse
gear. Follow the steps below:

Turn the ignition key to the “ON” position, but don’t start up the car. Put the gear shift in
the reverse position.
Take a measuring device for DC 12/24V to locate the positive and negative pole of the
reversing bulb seat. Warning: Be careful and don’t short circuit the positive and negative
pole!
Once you have confirmed the specific position of the reversing lamp circuitry, turn of the
ignition key.
Remove the negative ground contact of the battery. Note: Please tighten the power
cable to avoid tangling of the power cable onto any car part.
Reversing bulb seat on most cars have two wires. Normally, the black one is the
negative wire, while the colored one is the positive wire.
After confirming which is the positive wire and which is the negative wire, distribute the
power cable of the camera to the right position.

2 RED 5 Bulb of reverse light
3 BLACK 6 Ground
Use the in-line wire connector, splice the red wire onto the (+) wire of the reversing
lamp by use of the red connector* (*included).
 Then splice the black wire of the cable of the camera on to the negative (-) wire or
grounding point of the reversing lamp.
 Use of the cable clamps (DO NOT attempt this if you are not knowledgeable with
electrical installation practices.)
The camera can be wired directly to the reverse light circuit
by stripping the reverse light wires.
Insert the existing wire to be tapped.
Then twisting the camera wires to the exposed reverse light
wires. Insert the wire to be attached.
Crimp tap and then close lock.
Once they are connected, wrap them with electrical tape.

 Replace the reversing lamp bulb and reinstall the lamp seat.
 Use the cable ties or insulation adhesive to fix all wires.
 After finishing the wiring, don’t forget to reattach the negative ground contact
to the battery.
Additional: If you use a wired monitor it will be necessary to connect the power/signal
output port of the camera to the power port of monitor. When you use a wired monitor,
please connect the video input port of the monitor to the video output port of the camera.
The camera will automatically export signal to the monitor.
Note: The camera is compatible with both wired mode and wireless mode.
Installation of the monitor
There are 2 ways of installing the monitor in
the car.
Use the suction holder to install the monitor.
The suction holder is stamped on the front window
glass.
Use the air holder to install the monitor. Special
holder is plugged into the ventilation slot of car air
conditioner.
Put the monitor at the correct side which is most
convenient for you and the power supply is long
enough for.

Connect power of the monitor (2 ways possible):
Use the cigarette lighter adapter included in the package
to get the monitor powered.
According to the same step, find power from the car power
circuit in front, and connect the cables correctly. Use
Monitor wiring Harness (5). The cable also includes a fuse.
It can be changed by screwing the swell open.
Wired connection: If you use the wired connection from
the back of the car to the front (3.5mm Jack cable, both
sides ~8m) there is no need for an additional power
connection. Use a 3.5mm jack to connect camera with
monitor.
Testing the system
First step: Reattach the negative battery cable of the vehicle (if not done yet).
Second step: Engage the parking brake and turn the ignition key to the ON position. DO
NOT start the vehicle. Put the gear shift into reverse.
Third step: The camera will start broadcasting and the monitor will detect the signal and
turn itself ON. If the monitor does not turn ON, press the ON/OFF button on the top. (Still
no image appears on the monitor use button (8) to switch to channel 4. The channel
frequencies are: CH1 = 2414MHz; CH2 = 2432MHz; CH3 = 2450MHz; CH4 = 2468MHz)
Forth step: If the image does not match your rearview mirror, press the top button on the
right side of the monitor to change the image until it matches your rearview mirror.
Fifth step: When you take the gear shift out of reverse, the camera will turn OFF, and the
monitor will turn black.
Four different monitor views press the image orientation button (7) for choosing:
Normal Mirror Mirror upside down Normal upside sown
These different views allow you to mount the camera and/or monitor with either right side
up or upside down. The image is displayed correctly on the monitor and it should match
your rearview mirror. After testing the unit, fully tighten the license plate bolts. Route all the
wires behind interior panels or under carpeting so that they are hidden. Use the supplied
cable ties to neatly gather any excess wire. Keep the camera lens and monitor clean to
ensure the optimal picture quality.

materials and can be recycled. Do not disposal old devices or
batteries into the domestic waste. Cleaning: Protect the device from
contamination and pollution (use a clean drapery). Avoid using
