Rear view cameras with parking guidelines. How to choose a parking camera?
Car drivers have long been able to facilitate their tasks on the road with the help of electronic assistants. For safe and convenient parking, two groups of such devices are currently offered. parking sensors and cameras that broadcast a rear-view image. And if the first category of assistants is more suitable for beginners, then sooner or later experienced drivers turn to the second, realizing the value of such a solution both as a means of increasing safety and as a way to save time. In particular, rear-view cameras with parking guidelines allow you to control the movement of the car without distraction without the risk of collision with other objects.
What is the peculiarity of the parking lines function?
The first and simplest models of rear-view cameras were equipped with monitors that did not have this option. They transmitted the image in a natural “pure” form, allowing the driver to navigate in the real situation. Modern models, even in standard kits, are provided with the ability to reflect parking lines. These are pronounced graphic stripes on the display screen, which indicate the boundaries along which you can safely continue to drive. The principle of their overlay depends on how the rear view camera works in software. Parking lines in the latest models are adjusted depending on the position of the steering column and, accordingly, on the rotation of the wheels. This solution, of course, facilitates the driver’s actions, but it must be borne in mind that the slightest failure in the lining of the lines can lead to a collision. Therefore, you should not completely rely on them. when analyzing the movement, it is necessary to take into account the real situation, which is transmitted to the screen.
Which type of camera to prefer?
The cameras themselves primarily differ in design. Mortise models are good for their versatility. They can be integrated into the body of any car, however, a special hole is required for installation. In terms of installation, the best option. overhead camera. It does not require destructive intervention in the body and can be fixed with a complete bolt in the license plate light. But here you really have to select a model that suits the specific design of the mounting point. Reversing cameras with parking guidelines on brackets provide ample observation possibilities. Their distinctive feature is the ability to turn, changing the angle of view. They are installed in the cabin. for example in the rear window.
Performance selection criteria
During operation, two main parameters will be important. matrix type and resolution. They will determine how high-quality the transmitted “picture” will be. As for the matrix, cameras with two modules are produced today. First option. CCD system, the main advantage of which is the increased light sensitivity. That is, for parking in the evening. This is the most suitable option. CMOS has only one operational advantage, which is processing speed. Such rear-view cameras with parking guidelines with a monitor are capable of providing good dynamics of the video sequence, but their clarity will be far from perfect. In terms of resolution, choice is almost lacking. The standard format is considered to be 628×582 (0.3 megapixel) and it is completely enough to meet the tasks of a parking assistant.
Selection by viewing angle
The range of degrees of visibility is very wide, but their number does not always guarantee good image quality. Actually, the choice can be between 120 and 170 degrees. The standard is considered to be an angle of 120 degrees. In such broadcasting, the image is NOT blurred and on the monitor will be perceived as detailed. Still, 170-degree rear-view cameras with parking guidelines are heavily advertised by premium car manufacturers. Their advantage will be in the large coverage of the “working” area, so you shouldn’t immediately abandon such a decision either. Before choosing, you must first assess where the device will be installed and whether it can provide sufficient coverage at a small degree. Otherwise, the review advice will have to sacrifice clarity, and in some cases and sensitivity.
Selection by signal transmission method
This paragraph will focus on how the camera and monitor interact. A typical connection involves routing a wire almost through the entire passenger compartment, covering the luggage compartment. It is obvious that the use of video cables will be laborious and costly. Therefore, modern kits are being transferred to a wireless connection type. These rear-view cameras with parking guidelines interact with the monitor through an integrated radio module. The range can be up to 15 m, so there will be NO communication problems. However, there are two disadvantages in wireless systems: firstly, the high cost, and secondly, third-party electromagnetic interference can temporarily disable the device or distort the “picture”.
It will be useful to have a backlight in the display. At the same time in the evening or at night, the image on the screen may not be enough, and infrared illumination will add clarity to the “picture”. Also, external equipment should be well protected from dust and moisture. Multifunctional rear-view cameras with parking guidelines with a display, for the most part, also support the ability to connect to a DVR and TV tuners. In addition, the Auto Navigator is connected from the video input of the AV-IN format. In this case, the dashboard can be eliminated from the presence of SEPARATE devices with the above options.
Progress in the field of automotive electronics is annually mastering new technological solutions. The expansion of functionality, of course, is reflected in prices, but along with them, the quality of the product rises. Design excellence, new options and more advanced ergonomics. what characterizes modern rear-view cameras with parking guidelines. How to choose the most suitable kit? In addition to the above criteria, do not forget about secondary qualities. For example, experts recommend thinking over the possibilities for future communication of the device with other components of the standard equipment. The stylistic correspondence of the display to the interior should NOT be ignored either. Manufacturers regularly improve the design advantages of cameras and especially displays, therefore, in this parameter, there is plenty to choose from to your taste.
Setting up the markings of the parking lines of the rear view camera: change the world for yourself
Setting the parking lines of the rear view camera. the process is simple. Stay tuned and we’ll tell you how.
A rearview camera is installed to improve visibility while parking. The image is displayed on the monitor in a mirrored format so that our “brain” feels it in its usual form. That is why such devices are not suitable for front-facing optics. Scalable markings DO NOT display distance, but allow you to see the boundaries of the vehicle and surrounding obstacles (curbs, fences, poles, etc.). Thus, with such an optical assistant, even an inexperienced driver can easily cope with parking, even in very difficult places.
By the way, if desired, parking lines can be turned off. Someone they interfere, others do not need it due to the absence of problems with parking, still others are trying to adapt such a camera for the front one. Below in the article we will tell you how to remove the markings from the rear view camera.
Types of markup
Before we move on to adjusting the parking lines on the rear view camera, let’s find out what they are.
- Static layout with a straight grid. On the screen, it looks like two bounding guides on the sides of the car, with colored lines crossing them. Each color means a certain distance from the strip to the bumper. For example, green. 2-3 m, yellow. 1 m, red. 50 cm.Such markings are convenient when driving back in a straight line and completely useless if you park along a curve (twisting the steering wheel or out of a turn).
- Dynamic, in accordance with the angle of rotation of the wheels. On the monitor, it is displayed in the form of curved lines, which follow the trajectory of the machine. The mesh is also crossed by colored perpendicular stripes that characterize the distance to the bumper.
If you’re wondering how to enable the rearview camera markup, relax! The process starts automatically while driving in reverse. The picture appears on the monitor immediately after moving the automatic transmission lever to the desired position. Please note that a situation where the image does not turn on automatically may indicate serious problems.
Setting up parking guidelines
Next, let’s take a look at how to set up parking guidelines on a rear view camera.
The setting depends on the type of optical device. In the simplest case, the marking cannot be adjusted, it only needs to be calibrated once (to calculate the correspondence to real distances). This is done manually.
- Park the car directly in front of an obstacle (for example, in front of a curb), the bumper should be strictly parallel to it;
- Drive the car backwards so that the farthest parking line on the monitor coincides with the obstacle (green)
- Now get out of the car and measure the distance from the bumper to the curb. Now you know what distance the green line is measuring;
- Calculate the distances to other lanes in the same way;
- Remember the numbers you received. Now, while parking, you will know exactly how many cm separates your bumper from a wall or fence.
Next, let’s look at how to set up the markup on the rear view camera through the car radio (on the screen of which the picture is displayed). This is done through the Settings Menu of the standard audio system. The sequence of actions may differ depending on the car brand or the type of main unit. Here is the most common:
- Find a straight wooden stick (such as a shovel handle) and lay it parallel to the bumper, 1m away from the rear view camera. The middle of the bar should be exactly opposite the camera‘s eye;
- Further, find in the Car radio menu the section dedicated to the parking software settings;
- Turn on the device, wait for the image with the bar to appear on the monitor;
- Unscrew the steering wheel all the way to the right, then to the left (to activate the dynamic parking guidelines setting)
- Find the key, pressing which will select the bar on the monitor in a frame;
- Use the arrow keys to adjust the SYMMETRICAL position of the bar to a rectangle;
- Save the setting.
Some models of radio tape recorders require laying two calibration objects at a distance of 1 m and 2 m. There are also devices with which you should use a special stencil from the kit. If you need to configure the parking lines of the rear view camera on a Chinese car stereo with Android, we recommend that you search the network for instructions specific to your model (everything can be sooo unique there).
How to disable markup?
As promised, here’s how to turn off the markings on the rear view camera. There are several ways to do this:
- Via the Car radio settings menu. Just find the appropriate option and activate. However, not all OEM head units contain this setting;
- Check the optical device, it may have a switch. It can be used to disable mirroring and markup. The mechanism, again, is not present in all chambers;
- A radical method. cut the loopback wire in the rear view camera cable. Find the loop and cut off, the contacts are securely insulated. You can forget about parking lines forever;
- You can also remove parking lines on your rearview camera tool like a professional electrician. To do this, you need to disassemble the gadget and remove the elements responsible for the parking lines from the microcircuit. The method is suitable only for those who really understand the electronic modules of car gadgets. If you are NOT one of them. I do not recommend taking it, you can completely ruin the device. Then no setting will help.
As you can see, adjusting the parking guidelines in the rear view camera is easy. NOT twice or twice, of course, but thinking with your head is sometimes useful! We wish you easy and hassle-free parking!
We remove the horizontal stripes on the monitor screen, which appeared suddenly. How? I tell
Good day, dear readers and subscribers of my blog! I, Rostislav, recommend the article for a full reading in order to solve my problems in this topic. A computer. it is a complex device where all the elements are subtly interconnected. NOT high-quality operation of one of the nodes can lead to equipment defects. In order for the equipment to serve for a long time, it is necessary not only to take care of it, but also to carry out diagnostics. This will allow timely identification of the malfunction. NOT every user will be able to do this on their own. Today I will tell you what to do if horizontal stripes appear on the monitor screen, how to remove it will be described below. It is NOT rare that the problem is caused by a technical breakdown, but it is encouraging by the fact that there is usually nothing critical in this, which means that it will cope on its own quite realistically.
Why stripes appear
A monitor is a means for displaying images on a screen. It is closely related to various computer components. Sometimes multi-colored stripes. this is due to a driver malfunction or a virus failure. But software problems are rarely the root cause. Most often, the reason lies in the incorrect connection of the PC nodes or the negative impact of one of them on the other.
Before starting the diagnosis, it is worth checking what kind of defects on the screen. If the picture is simply warped or colors are inverted, then the likely cause is the driver. Updating it is a simple task. It is best to download the latest version from the manufacturer’s website. In the case when the screen is divided into stripes or disintegrates into pixels, then the reason is clearly in the hardware, and not in the software. Not all users know what to do in this case. There are many exceptions for the graphics card, but that may not be the question. Loose wires, overheating, dust. these are all possible sources of stripes. Therefore, first of all, I recommend disconnecting the computer from the network and starting sequential diagnostics of each element.
Why might the monitor deteriorate? often it is a physical impact. shock, increased moisture, sun exposure to the matrix. Sometimes a power surge or network noise can damage the device. I recommend all users to connect the monitor to the mains through a surge protector. This is a good defense. There is a nuance here. Sometimes an extension cord is used instead of a surge protector. When connecting different devices to it, noise may occur, which cause image distortion. In this case, we check the monitor by connecting it to the network separately. If this does not help, then we refer it to another. This is the easiest way to eliminate damage to your monitor and start checking the rest of your computer.
The second node, which is responsible for displaying the image on the screen. video card. It processes the incoming data and forms a picture. Like any device, it can burn out or deteriorate. In addition, it is susceptible to heat, clogging and other unpleasant phenomena. Diagnostics of a video card consists in cleaning it from dust, checking the cooler’s operation, and lubricating it if necessary. It is also important to check the integrity of the connection wires. Often the reason lies in them. A system unit accidentally hit with a foot, wires coming out of the connector. here is the image distortion.
If this does not help, all the wires are intact, the Card does not heat up and is NOT dirty, then we repeat the previous point. He removes the video card and again we go to visit another. The video card is working. So we are looking for the problem further.
Service employees often talk about the fact that most of the breakdowns are solved by checking or replacing the connection wires. It was said above that you need to check how the video card is connected. However, it will hurt to consider loops that connect other components. What is the verification? We eliminate dust, check the reliability and correct connections, inspect the wires for black dots, bends and fractures. For many years of using technology, many users DO NOT look inside their system unit and DO NOT suspect what anarchy reigns there. A lot of wires entangled with each other, covered with dust, and sometimes cobwebs. All of this will naturally affect the work. To make it easier for myself in the future, I recommend that after purchase, inspect the system unit, switch the wires and try to lay them as evenly as possible. In the future, this will allow you to avoid breakdowns.
While switching wires and checking connections It will not be superfluous to inspect the motherboard. There are many elements on it and an unprepared user will hardly find a problem himself. But it is quite possible to notice minor defects. It is about Burnt Resistors. These are small protruding parts. Most often they are in the shape of a cylinder, they can be of a variety of colors. black, green, red. A burnt out transistor will be black and with traces of carbon deposits. The second sign of its failure. bloating. You shouldn’t change them yourself, but this is a sign that it’s time to take the PC to the service center.
Checking the monitor matrix
I mentioned above that the appearance of stripes is often the result of a hardware failure. But sometimes the nuances lie in the setting. First you should try to reset the monitor settings to the factory settings. This is very easy to do. On the body of the device there are buttons that allow you to change the gamma, brightness, contrast. There is always a factory reset button among them. With its help, the monitor returns to factory settings.
To understand the correct operation of the monitor itself It will not be superfluous to check the integrity of the matrix and the presence of hidden factory defects. Sellers often use this trick to sell services to clients. It all sounds tricky and complicated, but in fact it’s done easily.
There are several ways:
- Using a special program;
- Video launch;
- Microsoft Tools.
Option 1. download special software to a USB flash drive and run it on a PC. There are a lot of programs, they take up little space, and they are quite easy to use.
Popular utilities include:
- Nokia monitor test;
- Eizo monitortest;
- Passmark monitortest.
These tools will allow you not only to identify the broken pixel, but also to check the matrix for color transition, contrast. In general, the check consists in driving the device to fill with one color. The dead pixel will be highlighted in a different color. Special gradation images help you determine if colors are displayed correctly.
Option 2. go to youtube and enter the query “matrix test” into the search. The principle is the same, only you don’t need to download anything. We just start the video, Expand it to full screen, remove all unnecessary elements and look carefully.
Option 3. in the OS settings there are special items that allow you to customize your desktop. Among other things, you can choose a background here. The verification process is reduced to removing all elements from the desktop, the taskbar and sequentially filling it with one color. In other words, this is a variation of the first option, you just have to dig a little in the settings. I do not recommend using this method, because it is the longest. Suitable if there is no Internet and Special utilities.
For those who all decide to turn to this method, the sequence of actions is below:
- Personalization. Options.
- Background. Solid color. Complementary color.
- You need to choose alternately white, gray, black, green, red, blue colors. It is on them that the pixels are noticeable.
- Go back to the Personalization menu and go to the Taskbar.
- Select “Automatically hide the panel on the desktop”. Now she will hide off the screen on her own. To return it to its place, just move the cursor down.
- The last point. Right click on the table and go to the “View” item. At the bottom we mark “display desktop icons”.
- After performing THESE actions, nothing will remain on the desktop except for the selected color. The action must be repeated for each of the above colors.
If the stripes on the screen are faint, and they more closely resemble Incorrect display of colors, then you can try to fix it by adjusting. There are a number of special programs that allow you to achieve the most accurate color display.
- Adobe Gamma. As the name suggests, this is the brainchild of a well-known company, giving the world Photoshop. Once the utilities were part of the main software, but later they were undeservedly removed, since they were created for CRT monitors. People who work with photography and images in general believe that it is quite applicable to modern devices. over, it is one of the best.
- Power Strip. The utility is good because it works with a whole list of video cards and gives you access to many settings. In it you can adjust Not only the color, but the clock frequency of the monitor and other important parameters.
The appearance of stripes on the screen. this is not a reason to buy a new monitor, video card or system unit. You can often fix the defect yourself, and I hope this article will help you do it.
