A modern car is impossible to imagine without driver assistance systems, and one of the most popular is the car. rearviewer. It allows you to safely maneuver in a limited space, eliminates the risk of collision with obstacles that are not visible in the mirrors, and greatly facilitates parking for beginners. Independent installation of this device is a problem that is quite solvable for a person who knows how to hold tools in his hands and understands the basics of electricity.
Unlike buying a car with a pre-installed option, self-mounting gives you complete control over the quality of the components and where they are placed. You can choose a model with night lighting, a wide viewing angle or integrate it into the regular boot button. The main thing is to strictly observe the sequence of actions and safety when working with the onboard network.
In this article, we will analyze all the nuances of the process: from the selection of equipment to the final configuration of the image. You will learn how to properly lay the cable, avoid interference from the generator and ensure reliable tightness of connections. Properly executed work will be the key to long service equipment and your confidence on the road.
Selection of equipment and preparation for installation
The first step is to purchase quality equipment. The market offers a huge variety of options, from cheap Chinese counterparts to professional systems. The key parameters of the choice are resolution Matrices, viewing angle (optimally 150-170 degrees) and video signal standard. Most cars use the NTSC standard, but some European models may require PAL, so checking compatibility with the head unit is a must.
Particular attention should be paid to the method of connection and the type of signal transmitted. Analog cameras transmit images over coaxial cable, whereas digital cameras may require more complex switching. Also important is the presence of IR illumination for work in the dark and IP67 or IP68 protection class, which guarantees resistance to water and dust.
When buying, pay attention to the presence of transitional frames in the kit - they often allow you to install the camera in a regular place without drilling additional holes in the body.
To work, you will need a standard set of tools: a drill, a drill, a set of screwdrivers, tape, screeds and a multimeter. Do not forget to purchase an additional wire if the standard set is not enough for laying from the trunk to the monitor in the front of the cabin. You will also need heat shrinkage to isolate the twists.
Definition of installation site and dismantling of elements
The choice of installation location depends on the design of your car and the type of camera you purchase. Most often, the device is integrated into the lamplight of the license plate, into the trunk opening handle or a separate hole in the bumper is drilled. Staffing place It is considered the most aesthetic option, since the camera becomes an invisible part of the body.
Before the start of drilling, it is necessary to dismantle the trunk skin and remove the ceiling of the illumination of the room. This will allow you to estimate the amount of space and the path of laying wires. If you plan to insert into the bumper, markup is made as accurately as possible using a template from the kit.
- 🔍 Visually evaluate the inside of the bumper for amplifiers or structural elements that may interfere with the installation.
- 🔧 Prepare the place for drilling, cleaning the surface of dirt and degreasing it with alcohol.
- 🔌 Make sure the hole diameter matches the camera's landing size, taking into account the sealing rings.
When removing plastic elements of the cabin and trunk, act carefully. Use plastic blades so as not to damage the paintwork and not break fragile clips. All removed fasteners fold in a separate container, so as not to lose them in the process of work.
⚠️ Warning: Before drilling any holes in the body, be sure to check the back of the metal. Accidental damage to wiring or fuel lines can lead to serious consequences and expensive repairs.
Cable laying and wiring organization
The most time-consuming stage is laying the cable from the place of installation of the camera to the head unit. The cable must be reliably protected from rubbing, moisture and high temperatures. For this purpose, corrugated tubes and standard technological holes in the car body are used.
It is best to carry the line along the regular wiring harnesses. It is not only aesthetic, but also safe. In the passageway through metal partitions (for example, from the trunk to the cabin), be sure to use rubber sleeves or corrugated so that the metal does not cut the insulation of the wire when vibrating.
If the video cable is too short, it can be built up using a high-quality shielded wire. The twists should be soldered and carefully isolated by thermal shrinkage. It is not recommended to use the usual twists "on the twists", as in conditions of vibration and temperature changes, the contact may disappear, and the image will disappear.
- 🚗 Lay the wiring under the trunk carpet and under the plastic sills of the cabin.
- 🛡️ Avoid proximity to high-voltage wires and sources of strong electromagnetic fields.
- 🔒 Fix the cable with plastic screeds every 30-40 cm to prevent it from rattling.
Connection scheme and electrical part
Connecting a rear-view camera requires understanding the vehicle’s basic electrical circuitry. There are usually three main wires used: power (plus), mass (minus), and video signal. Power is most often taken from the reversing lights so that the camera is turned on automatically when switching to reverse mode.
To find the necessary wire, use the multimeter in voltage measurement mode. When turning on the rear gear on the desired wire should appear voltage on the onboard network (about 12-14 volts). Massa can be taken from any metal body element or from a minus wire of normal wiring.
| Color of wire | Function | Where to plug in | Tension. |
|---|---|---|---|
| Red. | Nutrition (+) | Reversing lamp | 12 V (when switched on) |
| Black. | Mass (-) | Body / Minus the Lantern | 0 In |
| Yellow | Video signal | RCA monitor input | Signal. |
| Pink. | Trigger (Remote) | Monitor entrance (if any) | 12 V (onward signal) |
It is important to ensure that all compounds are securely insulated. Moisture that hits the contacts causes oxidation and signal loss. Use quality materials for insulation and try to place connections in places where water is least likely to get into.
What is the interference from the generator?
If the image shows floating stripes or ripples that change with engine speed, then the camera gets dirty power. In this case, you need to power the camera through a separate filter capacitor or take power from the battery through the fuse, and not from the lights.
Setting up the image and parkingtronics
After the physical connection, you need to check the system. Turn on ignition and backshift. An image should appear on the screen. If the picture is inverted or has a mirror image, find the switch on the camera body or in the menu of the head device for display correction (Mirror/Flip).
Many modern cameras have markup of parking lines. They can be static (drawn on the matrix) or dynamic (change the angle when turning the steering wheel). To work dynamic markup requires connecting an additional wire to the steering angle sensor or activating the function in the settings of the tape recorder.
☑️ System verification
If you are installing a camera with integrated parktronics, you will need to adjust the sensitivity of the sensors. This is usually done by choosing the distance to the obstacle at which the signal begins to sound. Do not make the sensitivity too high to prevent the system from reacting to rain or snow.
Typical errors and troubleshooting
In the installation process, beginners often make mistakes that lead to unstable operation of the equipment. One of the most common problems is poor mass contact. If the camera is unstable or the image is dull, first check the reliability of the connection of the sub-conductor wire with the body.
Another common mistake is using poor-quality video wire without screening. This leads to interference, especially if the amplifier power wires or other sources of radiation pass nearby. Replacing the cable with a screened one with ferrite filters usually solves the problem.
- ❌ The absence of a fuse in the supply chain is the risk of short circuit and fire.
- ❌ Poor sealing of the hole in the bumper - fogging of the lens from the inside.
- ❌ Twisted cable – can break when opening the trunk or vibration.
⚠️ Warning: Never leave twisted wires without insulation in places where moisture may accumulate. Even the minimum amount of water on the open contacts of a 12-volt network can cause electrolysis and break the contacts in a few months.
If the image is black and white, check the color coding standards (NTSC/PAL). The discrepancy between the camera and monitor standards often gives just such a picture. Switch the mode in the settings of the head unit or replace the camera with a compatible one.
The quality of the image is 80% dependent on the quality of the cable and the reliability of the contacts, not just the cost of the camera itself.
Completion of work and final assembly
Having made sure of the stable operation of the system, you can proceed to the final assembly. Install all removed plastic panels, trunk skin and rapids in their places. Make sure that the wires are not clamped or transmitted anywhere.
Take the final test drive in a safe place. Check how the camera behaves when reversing, whether there are delays in the inclusion and how the backlight works in the dark. If necessary, adjust the angle of the lens.
Self-installation of the rear view camera is not only saving money, but also confidence in the quality of the work performed. Compliance with all technological standards will allow you to enjoy a comfortable parking in any conditions for many years.
How do you extend the life of a camera?
Regularly wipe the lens with a soft cloth. In winter, do not clean the ice with solid objects so as not to scratch the lens. Periodically check the tightness of seals.
Do I need to remove the battery before connecting?
Yes, removing the battery's negative terminal before starting work with electrics is a mandatory safety rule. This will protect the on-board network from short circuit and prevent possible damage to the electronic control units of the car.
Why is the camera running late?
Delayed activation can be caused by several factors: slow initialization of the camera module itself, software delay of the head unit, or the use of a long, poor-quality cable. In some radios, the delay can be adjusted in the engineering menu.
Can I connect the camera to a regular DVD screen?
Yes, you can if the screen has a video input (usually a yellow RCA connector). However, automatic switching on in rear gear will require additional connection of the control wire (trigger) to the circuit of the reversing lights, if such a function is supported by the monitor.
How do you remove the ripples in the image?
Rising is most often caused by poor nutrition. Try connecting the camera directly to the battery through a separate fuse, bypassing the standard wiring of lights. Also, installing a capacitor in the camera's power chain to smooth out pulsations will help.
