Rear view camera pinout: how to get it right
In today’s article, we analyze the popular pinout of the rear view camera. If you thoroughly understand the topic, you can independently lay the wiring and connect the gadget. By the way, there is nothing difficult here, there would be a desire!
Rear View Camera. This is a device that transmits a visual picture of the situation behind the car to the display of the standard GU. Allows you to safely maneuver the machine while driving in reverse.
Pinout. This is a pinout, wiring, or cable pinout. If it’s easier. this is the diagram that the master is guided by when setting up the electrical connection of each wire of the device.
In other words, the wiring explains where each pin of a connector or microcircuit is connected, if there are several of them, such as, for example, in rear view cameras.
Wiring the rear view camera wires is needed in order to correctly bring all the current-carrying conductors of the gadget to the necessary contacts in the car’s electrical network.
Types of pinouts
The most popular type is pinout. three-wire. Most Chinese gadgets adhere to it, as well as simple cameras, and not burdened with an additional option.
Also, pinout of a rear view camera with a large number of contacts is in demand. for 4, 5 or even 6 wires. They allow you to activate the auxiliary capabilities of the device: infrared illumination, control from the rear movement switch, etc.
The most popular combination of connectors on the device is a cinch for video transmission and a socket for connecting the power cord. The latter often houses a voltage regulator.
For 3 contacts
Usually, all manufacturers adhere to the following wire coloring algorithm:
- The black. mass or minus;
- Red. power supply or plus;
- Yellow. video signal.
According to physics, an electric current flows in a closed loop. The positive terminal of the electrical element is connected to the power component (in our case, to the reversing lights), and the negative. returns to mass (chamber).
Thus, when pinouting the rear view camera into 3 wires, the first two (power) are connected to the reversing lights, and the video output. to the monitor in the radio (or to the mirror, depending on the device model).
Next, we will consider where and what to stick when pinout of the rear view camera connector to 4 pin.
As a rule, such devices come with a short cable, at the end of which there is a 4 pin (holes) connector. An extension wire with 4 contacts is connected to these holes:
- “” Power supply, activated after turning on reverse movement;
- “-” power supply, weight;
- Video signal (plus)
- Video signal monitor, ground (minus).
So, an extension cord is plugged into the 4-hole connector. Please note, just below the junction of the connector with the extension cable, the latter branches into:
- Two thin wires (usually red and black): “” and “-” to flyback lamps;
- And a thick video cable (inside two-pin: “” and “-“) with a connector for connection to the display (6.35 mm jack, 3.5 mm minijack, 2.5 mm micro jack or USB) at the end. Accordingly, it is pulled to the radio, if you connect to it. By the way, before purchasing the camera, make sure to match the connector on the HU with the connector on the cord.
Next in line. pinout of the rear view camera 5 pin (connector for 5 wires). It is used in fancy gadgets with additional functions:
- Infrared illumination;
- Enabling / disabling and configuring markup;
- Mirror / normal video display;
- And other service options.
Also, some Chinese rear-view cameras have a 5-wire pinout not for additional chips, but for activating the connection between the device and a standard car radio or an external display. Read the instructions for use of the device carefully.
So, when pinouting the rear view camera connector for 5 pins, the first 3 pins, as a standard, go 2 wires to power from the OX lights and 1 to the video output. Another 2. these are “-” and “” additional options.
Where to connect the last one. you decide. It is possible, like the device itself, to reversing lamps or parking lights. In the latter case, the picture with the image will be in color during the day, and at night. black and white. But the IR illumination in the dark will plow constantly. And with the first option, the video will always be in b / w format, but the backlight will turn on only when the box is switched to reverse driving mode. On the face. saving the resource of IR LEDs. In short, evaluate the pros and cons at your own discretion.
As you can see, they are afraid of the pinout of the wires of the backlit rear–view camera. Not worth it. Everything is simple, subject to general logic. The situation is the same with 6-pin wiring.
It is the sum of all the above pinouts.
- Base as in 3 pin circuit;
- Slice. from the 4 pin circuit (in the video output “plus” and “ground” are separated by separate terminals)
- Last 2 contacts. “” And “-” backlight (or other function).
So, with this pinout, the wiring is scattered as follows:
- Red for “plus” power supply;
- The black. on the “minus” power supply;
- Yellow. pulled to the display for video transmission;
- Another black (twisted pair with yellow). also to the radio (“minus”);
- Auxiliary service option power supply (plus), wiring color is usually white. Connect to the source at your discretion;
- “Minus” of the auxiliary chip.
That’s it! If you really understand, you can easily understand the pinout of the plug of even a Chinese rear view camera. Believe in yourself! Good luck!
Pinout tulip rear view camera for 3-5 wires for cars and trucks
Rear view cameras installed on cars and trucks differ in different connection methods. To connect THESE accessories to a radio tape recorder or monitor, different types of rear view camera pinouts are used for 4 wires (as well as for 3, 5 and 6 pins in the connector).
Pinout for 3 wires
This method is now the most common. The three-wire connection provides power to the camcorder module and captures an image signal and feeds it to a display device. A pinout with a large number of pins is also used.
This allows additional features such as infrared illumination for shooting in the dark and control from a reversing switch or relay to be used. In the latter case, you can connect 2 cameras and control them one by one. It should be borne in mind that the role of the third wire can be played by the shield video cable.
Car cameras can be equipped with different connectors depending on the manufacturer. The most common combination. cinch for video signal and standard power socket. A voltage stabilizer is often built into the cord. Manufacturers of Chinese car media complexes, designed to use a car view camera, complete it with branded chips. They can have from 3 to 6 contacts. The role of the negative pin can be played by the outer metal part of the connectors.
When using the same chips, different pinouts can be used, when wires of the same purpose are connected to different pins. Before purchasing a camera and a monitor, please make sure that the connector configuration is the same. Otherwise, the system may malfunction or malfunction.
First wire. This is a composite video signal output to a monitor located in a car mirror or radio. The second red conductor supplies power from the on-board network through a standard socket of the RP-2, RP-4 type or a proprietary connector.
To protect against interference, the video cable is placed in a screen braid, which is connected to ground inside the video controller and car radio.
When unsoldering the tulip, the signal wire is connected to the center pin and the outer conductor. with side contact connector.
There are 2 options for pinout of a car video camera for 4 wires. In the first case, the common video signal output and the minus of the hardware power supply are separated by separate terminals. This protects against various parasitic pickups and increases power reliability.
Another option for connecting a video camera with a 4-pin connector is to control the power from the reversing light switch. Thanks to this, the camera turns off or works in standby mode, until the reverse gear is turned on, in order to avoid useless power consumption and a quick failure of an accessory that is not designed for a long-term operation mode. In this case, power to pin 4 is supplied directly from the battery, since the operation of the device is controlled by a signal applied to pin 3.
Pinout for 5 pins (contacts) is used if it is necessary to use additional features of the camera. One of the common options for pinout for 5 pins provides for the presence of an additional activation wire that connects to a car multimedia device or monitor. This configuration is common on some cameras made in China.
The fifth contact can be supplied with voltage to enable or disable the graphic marking in the parking assist mode, switch the image mirroring mode and control other service functions. The car radio must support them.
This type of pinout differs in that all negative wires are brought out separately from the signal ones according to the following scheme:
- First. it is powered by reversing lights. The conductor is red.
- The second yellow color is used for video signal.
- Third. this is the shield video cable.
- Fourth. this is a minus of the camera power.
- Fifth and sixth. this is the plus and minus of the IR illumination power supply, respectively. They can be used to implement various service functions.
It is possible to activate the backlight on a rear view camera for a car when using a pinout for 5 or 6 wires. They are connected to the license plate lamps with the correct polarity. The backlight plus cable is often white. Thus, the infrared LEDs of the rear view camera turn on and off along with the side lights.
