A rear view camera is an excellent solution for controlling the movement of a car in reverse, since the mirrors do not allow you to fully see what is behind the car. Although you should not rely heavily on one video camera, because it also has its drawbacks (switching on with a slight delay, limited viewing angle, insufficiently clear resolution).
Connecting a rear view camera requires some knowledge and skills, so not everyone can do it on their own - you have to go to an auto electrician. But most drivers do an excellent job with this task, especially if you carefully read this connection manual.
Usually, cameras for video surveillance of the situation behind the car, on the board, the color connector is black - minus and ground, red + power, maybe 3.3 volts and 5 volts, yellow - complex video output. There is also a control - white or brown, but this depends on the manufacturer. Red, black and yellow are generally followed by all camera manufacturers. To check, connect it to the TV through the usual "tulip" - it should show.

The infrared light on the rear view camera displays the image in color when there is enough light, and when there is insufficient light, thanks to the IR light, it displays the image in black and white for about 5 meters. So, their presence on rear view cameras is relevant, unlike registrars, where they are of an advertising nature of “night shooting” without practical use, which cannot be said about the LED backlight on rear view cameras - better without them than with them!
Connecting two car cameras to a monitor
The principle of operation is such that when the reverse gear is turned on, voltage is applied to the coil, the rear camera is turned on, the power contacts of the front camera are open. When the rear camera is turned off, the relay turns off and is fed to the button through contact 87a plus. Turn on the button - the front camera works.
Installing a rear parking camera
Connecting the camera from the reverse (classically). The camera is connected to the reverse wiring: plus to plus and minus to minus. When you turn on the reverse speed from the reversing light, it goes to the reversing camera, and it sends a signal to turn on the monitor automatically, so no additional manipulations need to be done. The reversing camera will automatically turn off when reversing is disengaged. The camera is connected using a cord, which is initially available on the wiring next to the camera, or using a wire with a plug, for which there is a plug on the wiring of the camera.
There are even wireless rear view cameras (video transmitter and video receiver with a radio channel), then the connection will look like in the diagram.
Rear view camera mounting methods:
- to number plate light socket or in the trunk handle or a place for a camera - no damage is done to the car;
- number frame camera- the hole for the cord is not visible, since it is outside the frame;
- mortise chamber— according to the principle of a peephole, it is convenient among parking sensors, in a lock cylinder or just a body;
- on a pin- minimal damage, since the wire passes through the pin itself, invisible, installation with the pin up;
- invoices- have a certain angle and minimum dimensions, often have a certain position for installation;
- on bracket- convenient in that you can mount in almost all places and change the angle of the camera and rotate the image.
Please note that all cameras are usually powered by 5 volts, it has a voltage regulator and outputs 3.3 volts to the camera itself, for some this stabilizer can withstand 12 volts, but this is rare, it usually burns out. On ordinary Chinese cameras powered by 12V from a reversing light, a 5-volt stabilizer is soldered into a plastic fork of the wire for power and a tulip, and a 3.3-volt stabilizer is also in the camera itself.
Replacing the rear view camera - instructions
Like any other electronic device, these camcorders sometimes burn out (especially if they are constantly powered). Then the replacement steps will be:
1. We take the camera.
2. We cut off the regular harness from the camera, closer to the camera. It will be in a shielding braid, prepare the braid for soldering with another similar braid from the new camera.
3. A cord with a tulip-type connector departs from the new camera. A long cord is attached to it, which should stretch all the way to the screen. We won’t need all of it, since there is a standard wiring to our screen, to which we connect. We cut off the connector with a small piece from the long wire and clean it. There will be a central core inside the braid. We will need both.
4. Solder the wires of the cut standard harness to the new camera:
- Yellow on the regular one - to the central core, cut by the new camera.
- A braid from a regular one to a braid from a cut new camera
- Black on a regular one - to the negative wire on a new camera (usually black)
- Red from the new camera must be connected to the positive wire that feeds the reversing light (green with a white stripe)
5. We turn on the ignition, put the automatic transmission selector in position R. If there is an image, everything is done correctly.
If you feed the camera from the reversing light, there may be ripples on the screen when you turn on the camera - you will have to connect it from the supply plus through a relay. Turning it off is mandatory, because if + 12V is constantly supplied to the video camera (for example, from the license plate light), then sooner or later its voltage converter will burn out.
Do not forget to carefully solder and insulate everything, preferably with heat shrink. It is advisable to cut the cords with a margin so that you can quickly replace the camera in the future without disassembling the skin. Before cutting the cords on a standard camera, you need to be sure that it is not working. The issue of attaching a new camera is purely a locksmith and is solved without problems. It is better to take an infrared camera - it “sees” better in poor lighting conditions.
Video instruction
Parking a car always requires special care. But if you are a driver with a little driving experience, then parking is probably difficult for you. Often, many resort to the help of third parties to help correct your actions when parking. But if there are none, and you are alone? To do this, manufacturers of auto products specifically produce rear-view cameras that are attached to your car and connected to any device to display the information received from the camera on the screen.
To date, you can find various models, but in order to make a choice, you need to navigate the main characteristics of the rear view cameras.
In this review, I will tell you what you should pay attention to when buying this type of device.
When buying a rear view camera, you need to follow a small list of step-by-step actions when choosing.
1) Since many car enthusiasts appreciate and love the appearance of their car, the big and main question when choosing a camera is its installation location and how it is attached to the car. Think in advance about which camera suits you according to these characteristics.
2) The second question that should worry you is where will the images from the camera be displayed? Will it be a head unit with video input, a portable external player, or a separate built-in monitor?
3) Next, you should decide how you will organize the "transport" stream of image transfer from the camera to the screen. Will it be standard wired or wireless transmission...
4) Only after you have decided on all three points, you can start “screening out” the proposed options according to the main technical characteristics: Matrix type, viewing angles, minimum illumination, color system, IR illumination, parking lines and IP protection.
Rear view camera type
Each rear view camera differs in its mounting method and its installation location. It is customary to distinguish four types of design of rear view cameras, namely:
Standard rear view camera
A similar type of camera is mounted on a regular place in the car, such devices are manufactured by the car manufacturer, and the camera has a “hidden” installation (not conspicuous).
Some manufacturers produce rear view cameras that are mounted in place of the license plate light, while the backlight is not disturbed, as it is provided in the design of the camera. Such cameras are not available for all car brands.
Flush-mounted rear view camera
To install this type of cameras, it is necessary to pre-drill a technological hole for its installation. Fixing is done with latches or locknuts.
Camera built into the license frame
A common type among motorists, since a miniature camera is located in the center of the license plate. Such a frame is often suitable for installation in almost any car.
Universal rear view camera
The type is due to a simple design, thanks to which, the camera can be installed on any machine in any suitable place. To fix such a camera to the body of the car, you must either use adhesive tape or drill a hole in the body and fasten it to bolts with nuts or screws.
Image output and video signal standard
When choosing a rear view camera for a car, you need to think in advance where you will connect it. To date, there are several ways to display an image:
1) Displaying the image on the monitor. The monitor can be built into the rearview mirror, built into the side panel or into the sun visor;
2) Displaying the image on the screen of the head unit with video input;
3) Output to a portable media player.
 |  |  |
If your car has a standard monitor, then this will facilitate the display of the image, since in the absence of such an option, you need to purchase the required accessory for your car.
One way or another, the requirements for monitors are the same. The most important thing is that the device supports NTSC or PAL TV signal. This standard affects the choice of camera as the supported monitor standard may not be compatible with the camera standard.
Video transmission method
There are two ways to transfer video from the camera.
1) Standard wired connection is via a cable from the back to the monitor. This method of transmission entails a number of additional actions for dismantling the skin and laying the cable inside the car. The picture quality in this case will be good, plus this method is reliable.
2) Wireless connection is carried out using additional auxiliary transceiver devices that are located at the camera from the back of the car and near the monitor. This method of video transmission is more suitable for navigators or portable media players. For monitors that have a drive wire, this method will not work. When transmitting a video signal, interference in the form of "snow" on the monitor may occur.

Camera sensor type
CMOS and CCD are two types of sensors used in rear view cameras. Each type converts the image into a digital signal using its own technology. But one type of matrix is lower in price, the other is better in terms of signal conversion quality.
Infrared illumination is not found in all camera models. To be honest, in the case of rear view cameras, LED backlighting is not effective. With the help of a light sensor built into the camera, the backlight turns on and off automatically at the right time. The inefficiency lies in the fact that with insufficient light, the color camera becomes black and white. Therefore, think about whether you need such an option in the camera or not? After all, reversing lights are able to provide quite suitable lighting.
Protection standard
The rear view camera is subject to harsh operating conditions, which is why the protection standard is an integral part. In cameras it is possible to meet degree of protection as IP 66, and IP 67 and IP 68. The first digit of the protection standard is responsible for protection against dust, the second against moisture. IP 68 has the highest level of protection - such a camera is maximally protected from dust and moisture.
It is also important to pay attention to the operating temperature range. In our country, this parameter is especially important, since the differences depending on the location and time of year can be significant. That is why it is necessary that the camera can work at any time of the year at any temperature. The lowest value that I personally managed to capture in practice is -40 ° С. Despite the fact that the manufacturer declared a minimum operating temperature of -25 ° C.
The only thing worth paying attention to is the power supply of the camera, often the power supply should not exceed 14 V, and if the car has an on-board network designed for 24 V, it is necessary to resort to step-down inverters.
Pre-considered choice of rear view camera, this is a 100% successful purchase. Since the "right" camera plays an important role in the life of your car. Yes, and it will be many times more convenient for you to park and maneuver in reverse with the help of a camera.
Price criteria
Having studied all the information provided, it's time to estimate your financial capabilities.
Up to 2000 rubles, universal and mortise cameras are available, with a viewing angle of up to 170 degrees. The main matrix type of such models is CMOS, and the protection standard is IP66-67.
From 2000 to 3000 rubles, both mortise and universal cameras are available, as well as those mounted in the license plate frame and of various colors. In these models, you can already find models with a CCD type matrix. But the degree of protection of the cameras is mainly IP67.
From 3000 rubles, different types of cameras are available, more expensive models have large viewing angles, and almost similar technical characteristics with the previous price category. Therefore, this case is an example of when you should not overpay an extra couple of thousand rubles.
I hope that this material will be useful to you. That's all for me, thank you for your attention! Good luck on the roads!
The rear view camera helps the driver when parking the car. It is very important to choose a model that would meet all the requirements for these devices. The article will help to understand the existing types of devices, their characteristics, the right choice.
[ Hide ]
Rear view camera technical parameters
The rear view camera is designed to transmit the video image behind the car to the monitor inside the cabin. It connects to a standard monitor, video navigator or an additional screen. Such parking devices are present in almost all modern cars. With IR illumination and changing the viewing angle, they help the driver to assess the situation behind the car and park correctly, even in absolute darkness.
When choosing a parking camera kit for a car, it is important to know the main characteristics of these devices and consider the following factors:
- The image must be transmitted in a mirror image, otherwise it will be inconvenient to use the device.
- The viewing angle of the device should exceed 110 degrees, but it is better if it is 150 or 170 degrees.
- Environmental resistance. This parameter determines how the device is able to work under adverse conditions: snow, rain, dust. Defines its temperature range and protection class of the device.
- The clarity and quality of the image depends on the resolution. Inexpensive kits have a resolution of 720x576 or 582x500. More expensive models - HD and Full HD.
- An important parameter for parking cameras is the marking, it makes it possible to park with an accuracy of 10-15 cm; The rear view camera with dynamic markings is especially convenient.
- Additional illumination is very important in order to get a high-quality image, especially at night, IR illumination increases visibility at night.
An important parameter of a video device is its matrix.
In its production, one of the technologies is used:
- complementary metal-oxide semiconductor (CMOS, English CMOS);
- devices having a surface-charge connection (CCD, eng. CCD).
Matrices made using CMOS technology do not work well in low light, transmitting an image with poorer quality. Despite this, matrices of this type have two advantages: progressive scan - both high-quality and low-quality signal lines are sequentially transmitted to the monitor; they are cheaper than PSZ matrices.
Devices with surface-charge communication transmit a better image to the monitor in low light, but they require more energy and lose to cheap counterparts in speed (video by Volodamdes).
Kinds
There is a wide variety of parking cameras on the automotive market.
They can be divided into the following three types according to their location:
- universal, which are mounted in specially designated places;
- devices that are built into the license plate frame and are sold bundled with them;
- regular cameras that come from the factory and are developed for each car individually.
Universal cameras have many advantages over standard counterparts. They have a simple design, so by purchasing a kit, a universal device can be easily mounted anywhere in the car. The shape of the universal video camera resembles a butterfly. The main advantage of these devices is their low price. Universal video cameras are hermetic, thanks to modern materials, they are resistant to scratches and moisture.
There are universal devices that are mounted in the rear bumper of a car. They are equipped with IR illumination, which provides visibility in the dark.
The disadvantage of these universal models:
- to install them, you need to drill the bumper of the car;
- insufficiently protected from mechanical damage;
- there is no possibility to adjust the viewing angle up to 170 degrees.
The simplest option is a rear view camera built into the license plate. It comes as a kit and does not require installation, the driver does not need to think about installation. In addition, the driver can adjust the viewing angle in relation to the horizon of the video camera built into the license plate.
An important advantage of built-in devices is the ability to install on cars of any make and model.
The device transmits a clear picture. Its design is sealed and weatherproof. It can be operated at temperatures from -30 to +50 degrees. To improve visibility at night, IR illumination is installed. The disadvantage is easy access, anyone can damage or remove the device.
The standard rear view camera is the best option. It is installed in the places provided by the manufacturer. Usually, the trunk opening handle, the IR lampshade of the license plate light are chosen as the place of standard installation. IR illumination improves visibility at night.
The advantage of regular cameras:
- designed for specific car models;
- equipped with IR illumination;
- during installation, the optimal viewing angle and height are set.
A convenient option for viewing the space behind the car is a rear-view mirror, to which the video camera is attached with a tripod. A mirror option is possible, in which a rear-view camera and a car DVR with a monitor are built-in. A retractable rear view camera with IR illumination can be installed on the car.
According to the method of installation, the video camera can be mortise and case.
Connection
The image from the rear view camera can be transmitted to a specially installed monitor, a standard car screen and a car navigator. To connect the device to any type of monitors, you need a video output that supports PAL or NTSC TV signal. It is important that the devices are compatible. The instructions include a wiring diagram.
Transferring an image to the screen can be done in two ways:
- A video cable runs through the entire interior of the car to the screen, which is installed on the dashboard. With this installation method, a signal is reliably transmitted that is protected from radio interference. The downside of such an installation is the need to dismantle the upholstery of the car interior.
- With the wireless method, the signal is transmitted by radio waves. The system is easy to install, but has many disadvantages: a small transmission range (no more than 15 meters), a large amount of electromagnetic interference, etc.
Installation by car service specialists is expensive. It is more profitable in terms of finances and time to buy a kit and install it yourself using the connection diagram.
Conclusion
The choice of video cameras is large, it is better to select a standard device, but there may be problems with the size and shape, since each car model has its own standard camera. If you have problems finding a standard fixture, you can purchase a universal one that fits the parameters.
A rear view camera with dynamic markings is useful for drivers who have to constantly park their car in unfamiliar places. Thanks to the video image received on the monitor, the driver will be able to see all the obstacles in the parking lot. He does not have to, as in the old days, turn his head to assess the situation behind the car. For the dark time of the day, cars are equipped with IR illumination.
The rear view camera can be used as an addition to the car, making together a set of video devices with which you can record travel. Information from the cameras can be used to identify those responsible for the accident.
Video "Parking cameras overview"
This video provides an overview of wired and wireless parking cameras, and also demonstrates the process of connecting devices (the author of the video is Observer Krasnodar).
Compared to parking sensors, a wireless rear view camera has an important advantage - visual contact. These are not squeaking sounds and parking sensors numbers, but a real image, the quality of which depends on the camera and monitor. Moreover, the latter is installed on the instrument panel, included in the multimedia system or can even be mounted in the rear-view mirror. Another advantage is the simple installation of a wireless rear view camera (you can even on the roof!), When compared with parking sensors.
Cons of the gadget:
- it is necessary to constantly monitor the cleanliness of the camera, otherwise it will become useless when there is dirt and dust on the street: and it is precisely in such conditions that the device is most often needed;
- wireless devices may cause radio interference;
- some car owners note that the monitor can be distracting and the driver, when reversing, will not notice what is happening in front of him.
An interesting piece of advice is given to beginners by experienced "tuners": it is better to install both systems - they complement each other perfectly.
Parktronic
In another way, it is called a parking radar, or an acoustic parking system (APS). The device accurately determines the distance from your car to the nearest object. Ultrasonic sensors (there can be up to 8 of them) “see” the obstacle not only from behind, but also from the front, from the sides. The parking sensors work on the principle of an echo sounder, that is, like a bat: it sends signals and picks them up, displaying the results on the screen and confirming them with a sound (beepper). As soon as the driver begins to drive closer to the obstacle, the signal becomes more frequent, and then becomes completely continuous. The device works when the reverse speed is turned on or when the brake pedal is pressed, if the sensors are on the front bumper.
Disadvantages of APS:
- the parking sensors cannot cover the entire space around the car with their ultrasonic “look” and, for example, will miss a metal bar sticking out of the ground;
- low sensitivity, especially characteristic of relatively cheap devices;
- high cost: budget products will “pull” no less than 2,500 rubles, and those that are more perfect can cost all 20,000 rubles.
How to choose a camera
Before you buy a wireless device, you need to consider the classification of cameras of this type. Signal transmission can be carried out in two ways:
- FM broadcast. The data is received via a conventional ultra-short-wave channel by an analog method through a receiver. To display the picture, a navigator or monitor is used (often the one in the multimedia system is used).
- Wi-Fi broadcast. Here, the signal is sent to a mobile device, for example, a tablet that has Internet access. In order for the device to work properly, you will have to download the application. A similar model will cost more, but now they are becoming more popular.
Design features also need to be taken into account. In this regard, manufacturers offer three types of parking assistance device.
- mortise cameras. It is mounted in the rear bumper and fixed there by means of latches or a stopper. The downside is that you have to drill a body element, but after installation, such a camera does not differ from the standard one either in functionality or in appearance.
- Universal devices. Not as popular as previous devices: they are distinguished by the possibility of installation in any place behind the body - above the license plate, on the bumper, etc. The products are fixed with double-sided tape or self-tapping screws. Universal cameras are good because they can be removed, rearranged if desired, change the viewing angle. However, this plus can turn into a minus, attracting the attention of intruders.
- Cameras in the license plate frame. It is characterized by ease of installation, has a mechanism for changing the viewing angle vertically. But it is also quickly removed, which is fraught with theft of the product.
- Ceiling cameras. They are installed instead of the standard sign frame, designed for a specific brand of car.
- Products on brackets. Equipped with a base that can rotate, which allows you to change the viewing angle. You can also install such a camera inside the car at the rear window: it will not get dirty and will not be stolen. But there is also a minus - glare is possible.
First of all, this is the viewing angle: it can be in the range of 60 - 120 degrees. There is an opinion that the more it is, the better. But that's not the case at all. An excessively large coverage angle distorts the image due to compression, which complicates the task of determining the correct distance to an obstacle (object). On the other hand, a small viewing angle forms “blind” zones, which is why the driver has to turn his head or look into ordinary rear-view mirrors. The best viewing angle is 100, 20, 140 or 170 degrees.
Other parameters to consider when choosing are as follows.
- Permission. For conventional cameras in the middle price segment, it is usually 720 x 576 or 582 x 500 pixels. The best resolution for HD cameras, where a CCD matrix is used. Budget models use CMOS sensors. They differ from their expensive "brothers" in less (almost 100 times!) energy consumption.
- illumination. If its level is low, then the contours of the object are visible in almost complete darkness. The lower this parameter (the minimum value is 0.01 Lux), the better.
- Protection from external factors. This refers to the ingress of moisture, dirt and dust into the chamber. The parameter of medium cost cameras is in the range of IP 65 - IP67. For the most protected devices, this parameter is IP68.
- Housing material and ease of installation. Chambers made entirely of metal are more expensive and heavier and corrode. Plastic devices may crack when fixed. The most optimal is the middle option, when the mounting platform is made of metal, and the body is made of plastic.
- Range of action. This characteristic is relevant for trucks, especially trucks. On average, the signal transmission radius is 9 - 11 m, but on some models it reaches 17.
- Backlight. These are infrared rays that improve visibility in low light conditions. As sources of IR flux, LEDs are used, placed around the perimeter or circumference of the lens. The presence of such an option is at the discretion of the buyer: reversing lights give much more light.
- Parking lines. This is a rectangular grid that makes it easier to determine the distance to an object. If necessary, the function is disabled.
- Mirror reflection. Designed to facilitate the perception of the picture, making it like in a rearview mirror. The option can also be disabled.
- Working temperature. For the best models, the range is from minus 25 to plus 65 degrees. But in reality, most cameras do not fail even in more severe frost.
The best models of wireless rear view cameras
If your car has a multimedia system, but no rear view camera, you should buy this accessory. But which one to choose? Below are the most popular models.
Garmin BC-30
A modern powerful premium camera equipped with a Wi-Fi module operating at a distance of up to 17 m. The image can be displayed on a separate monitor or navigator from the same company. Crashes into the rear bumper and connects to the standard reverse optics. The cost is around 10 thousand rubles.
Neoline CN10
The wireless device is suitable for all car models and is easy to install. Can be connected to navigation and other systems with AV-IN input. The device has a color matrix that provides a viewing angle of 170 degrees. Infrared illumination operates within a radius of 4 m. High dust and moisture protection: IP68. The average price is 3500 rubles.
Incar VDC-007
A good strong "middle peasant", installed in the license plate niche. The viewing angle is 135 degrees, the optics are waterproof. A rational solution for installation on a car of a budget category. Cost - up to 2700 rubles.
ZM701
It is installed in the license plate frame and is characterized by a good view - 170 degrees. Has the reliable and well protected case (IP68). For fastening, only self-tapping screws are needed. Cost - up to 3200 rubles.
Self-installation of the camera
The first thing to decide before installing the device is where you want to put it. Next, you need to prepare pliers, self-tapping screws and a screwdriver (in some cases, you will need a drill). Taking into account the above design features, the camera is installed:
- On the frame of the sign. Since it is plastic, fastening is carried out using self-tapping screws and a screwdriver.
- Into the sign's lampshade. On sale you can find models equipped with transitional glasses: this allows you to leave the factory lighting intact.
- In the luggage handle. If the plastic molding forms a single structure with it, then the rectangular chamber is fixed without problems with self-tapping screws.
- Into the bumper. You don't even have to take it off. It is enough to drill a hole and put the accessory case on a sealant or glue.
The camera lens will be less dirty if you install the device in the trunk lid with a glass washer. Buy a tee and insert it into the factory supply line "anti-freeze", and install a nozzle above the chamber.
Disconnect the battery before starting work. Wireless modules for connecting to a monitor can be of two types: with a 2.5 mm mini-jack (connects to navigators with a video input) and "tulip" (connects to equipment with an RSA input). In the latter case, one transmitter is connected to the reversing lamp, the second to the power source and the monitor. In the second case, the module into which the charger from the navigator is "plugged" is placed in front of it. More about the installation steps:
- After installing the camera outside the car (for example, above the license plate), you need to connect the transmitter to it using the supplied cable. To do this, you need to drill a small hole in the trunk lid or run wires (there are two of them: a red “plus” and a black “minus”) under the rubber seal, if the design of the car allows it. Sometimes the cables are already connected to the module in a permanent way. Next, install the transmitter itself inside the trunk. Connect the plus to the reversing lamp, and fix the minus with a self-tapping screw in any convenient place connected to the metal parts of the body.
- Now you need to connect the transmitter in the cabin. Here, two wires come from the module: one for connecting to the monitor (see above about the types of plugs), the other for power supply (to the cigarette lighter).
Camera check and setup
When all connections are made, connect the battery. Start the engine and engage reverse gear. If a normal picture appears, you did everything right. If the image is fuzzy or not at all, you need to find the camera in the multimedia system (radio) or navigator. For this:
- find the "settings" item;
- enter the "camera" sub-item;
- find your device in the list and activate it;
- if there are focus settings, then use them to get a high-quality image.
Conclusion
The purchase and installation of a wireless rear view camera will not only increase the safety of parking, but also make this difficult process for a beginner easy and enjoyable. At the same time, a properly installed camera is almost invisible and does not spoil the appearance of the car.
7 ratings, average: 4,14 out of 5)Rear view cameras for cars greatly facilitate the process of parking, especially for those drivers who often have to park in unfamiliar places.
The camera, which allows you to increase the viewing angle and see places that are inaccessible to the eye, will be an excellent assistant for both novice motorists and experienced drivers, providing them with comfort and traffic safety.
Pros and cons of rear view cameras
The prototype of parking cameras are ordinary video cameras.
But car rear view cameras have advantages that make this device indispensable in some situations.
Advantages:
make it possible to park at night with sufficient visibility of the parking lot;
The viewing angle is at least 130 degrees, which allows the driver to view a large space located behind the car;
In rear-view parking cameras, objects are displayed in a mirror image, that is, the location of objects is correct.
If the object on the monitor is visible on the left side, then it is in reality - on the left.
What is seen on the screen on the right side is on the right.
Flaws:
if the model of the rear view camera on the car does not have a bias towards the infrared range, it will be more difficult to park with it at night due to insufficient visibility.
But most conventional rear-view cameras now work with infrared illumination, so visibility is still quite good at dusk;
Infrared cameras are more expensive than conventional cameras, but the high image quality even in complete darkness more than pays for the costs.
Where is the rear view camera installed
Most often, the rear view camera is installed in the area of \u200b\u200bthe license plate.
This choice of location is not accidental. Provides the best view, and also due to the requirements for wiring from the camera to the monitor through the existing holes in the body.
Models of wireless rear view cameras transmit an image to the screen in the FM band.
In this case, there is only one wire - the supply wire, but connecting it to the car's on-board electrical network is quite simple.
A rational option is to use a GPS navigator, as well as a DVR.
These devices must have the function of connecting a parking camera, which allows not to use the car monitor.
The interaction of these devices allows you to save money and make the most extensive use of the working area in the area of the side glass and dashboard.
How to choose a rear view camera for a car
The choice of a parking video camera is a responsible step.
Ignorance of some subtleties may lead you to buy a device that may not meet your needs.
So, tips for choosing:
1. The viewing angle of the parking camera must exceed 110 degrees. Best option: 150-170 degrees;
2. The camera must transmit a mirror image of the picture from the street to the screen.
