How to properly set up a DVR

How to properly configure the DVR yourself date and time

• Setting the setting language. We exhibit - Russian;
• Recording permission. Here you can configure, in addition to the resolution itself, the number of frames per second. The ideal option is Full HD 1920×1080 30p. In some cases, the manufacturer may recommend setting other indicators; Set the camera rotation. Here you can select the options rotation, top-bottom. With a standard camera installation, the “top-bottom” indicator is selected;
• Adjusting the length of the recording cycle. Most models have the ability to set time periods for one file from 1 to 45 minutes. For greater convenience, it is recommended to select a period of 5 minutes. In this case, after taking up all the space on the memory card, new segments will be recorded over the oldest recordings;
• Be sure to turn on the time function. This may be necessary if there is a need to dispute with the insurance company or another participant in the accident in court. Find the time tab, usually there is a “time stamp” mode. It should be switched to the ON position. Next, set the date and time. Some models allow you to synchronize time via satellite;
• The light frequency allows you to adjust the lighting flicker filter. In our country, lighting is used with a frequency of 50Hz, we set this value;
• Auto-record. This function allows you to turn on the camera when moving within the field of view of the sensors. This way you can control what is happening to your car while it is parked. Don't forget to set the shutdown time. It is recommended to do 30 seconds after the end of the object's movement;
• Setting up a GPS receiver. This allows you to display movement speed and coordinates on video. Please note that not all DVRs have this capability;
• Setting up the G-sensor. This is necessary to protect the recording in case of an accident or when driving on bumpy roads. When driving on poor surfaces, it is recommended to disable the function completely;
• For use in winter, it is advisable to delay the start time by 10-20 seconds. This will allow the camera to turn on only after a certain period of time after the engine starts. The function is also useful in case of ignition problems;
• Setting the exposure. It is better to choose automatic;
• We set the contrast to the “normal” position, and also do the same with sharpness and brightness;
• Day and night exposure. Automatic mode is suitable for daytime operation. Night exposure can be turned off.
• If you leave it on, the camera will independently select the exposure mode depending on the time of day.

How to configure the DVR to use all the capabilities of the device?

When purchasing a car recorder, many car owners do not suspect that the quality of the device depends on how correctly the DVR was configured. Each model has its own rules and nuances; in this article we will describe the algorithm for how to set up a DVR.

1 How to properly configure the DVR?

If the installation of the device in the car is complete, all connections and fastenings have been checked, you need to make menu settings for normal operation of the device. Most models have an automatic activation function when the adapter is plugged into the cigarette lighter socket or when the ignition is turned on (depending on the connection diagram and installation).

Setting up the DVR menu We recommend that you read

After activating the car DVR, it immediately goes into recording mode, so to start setting up various parameters, you need to stop recording with the appropriate button and go to the menu sections. The menu has different tabs for easy setup - video recording, multimedia, settings. First of all, you need to configure the following on the device: Language, date and time - are set for comfortable work with the DVR and to obtain up-to-date data when recording video.

Next, we move on to the recording resolution and cyclic settings - in the settings menu you need to select the optimal video recording resolution (1920x1080) and frame rate. In this case, everything depends on the capabilities of the device, but it is necessary to set the correct resolution to avoid interpolation (forced video expansion), which degrades the recording and image detail.

Setting the video resolution of the car recorder

After this, you should configure the recording duration of one video, and also activate or disable the cyclic recording function (Recycle Yes-Not or the “rerecording” tab in the case of the Russian-language menu). Thus, when the memory card is full, the recorder will superimpose one video on another in a circle. Without settings, this process will be inconsistent, and the necessary videos may suffer from overwriting. The optimal recording time for one fragment is 5 minutes.

2 Go to additional parameters

So, everything basic is set up, now let’s look at the additional functions of your unit.

• Audio recording is a function that, when activated, turns on the microphone. It is especially relevant in the case of “communication” with traffic police officers.
• Motion sensor – when this function is activated, the DVR automatically starts recording if there is any movement of objects in the visibility area. It is better to activate this option selectively by adjusting the sensitivity level (if the functionality allows). It will come in handy when the car is parked; there is no point in using a motion detector while driving.
• Automatic screen shutdown is a function that allows you to configure automatic shutdown at a certain frequency; setting the option is relevant at night.
• Backlight, flash and network frequency - adjusting these parameters will eliminate various flickering in the frame and improve shooting under artificial lighting. The standard flicker frequency is 50-70 GHz.
• GPS connection status – a tab that displays the connection of the GPS module or activation of the built-in function in the menu. Setting the parameter allows you to get the coordinates of the trip, the speed value and display all this on the recorded video.
• G-sensor or shock sensor - you need to choose the optimal sensitivity level, taking into account the quality of the road surface, etc. It is best to set the sensitivity to a medium level. The option itself allows you to avoid video loss and automatic re-recording in the event of a collision or emergency braking.

A device with the function of connecting a GPS module.
There are other parameters of the car recorder, which can be configured before use - exposure, contrast, sharpness, screen brightness. However, they do not significantly affect the quality of video recording and the overall performance of the device and can be configured at the discretion of the car owner.

3 How to control the device via the Internet?

Every motorist should have a universal device for diagnosing his car.

You can read, reset, analyze all sensors and configure the car’s on-board computer yourself using a special scanner.

Many models of DVRs have the ability to connect to a remote control system, so the car owner can control the operation of the DVR via the Internet. To do this, you need to configure the device correctly. This can be done in several ways - either use a 4G modem from a cellular operator or connect the DVR via a Wi-Fi router and display the parameters on a computer.

In the first case, you will need an active Internet modem with a SIM card, a computer and a DVR that supports this type of connection. All settings for connecting a modem can be obtained from the operator who provides the device. To synchronize, you need to insert the modem into the USB connector, go to the menu and activate the Advanced Settings or network settings tab, in the list you need to select the connection type (3G: 4G) and fill in all settings with data from the network operator.

Connecting the DVR via the Internet

For remote control via the Internet on a computer, you need additional software (as a rule, it is included with the DVR) and a reliable browser. After installing the program, you should log in and find the Device Manager tab, in which you must select the IP of the connected DVR. Next, IP and other settings need to be set in the browser settings and managed via the Internet. If you use a Wi-Fi connection, you must configure the DVR to a static IP, from which the signal is redirected to the direct IP address of the router or mobile device.

To do this, in the DVR menu in the “Network” section, you need to replace the automatic acquisition of an IP address with a static one.

In the settings, manually enter the mask, gateway (according to the settings of the device to which the recorder will connect), the current address, confirm that the settings are correct and reboot the device. After this, you should activate the ports on the router and remote control via the Internet. In this case, local IP addresses must be reserved by MAC address in the device settings management section. If it is not possible to configure and connect a dedicated IP address for the device, you can select a DDNS service using a domain name.

Do you still think that diagnosing a car is difficult?

If you are reading these lines, it means you are interested in doing something in the car yourself and really saving money, because you already know that:

• Service stations charge a lot of money for simple computer diagnostics
• To find out the error you need to go to specialists
• The services use simple impact wrenches, but you can’t find a good specialist

Review of car DVR DNS EV-200 tests

Classification of memory cards
The appearance on the market of video recording products combined with positioning devices is due to the fact that in some cases, in order to fully prove innocence, traffic police officers need to provide not only a visual display of events, but also data on the vehicle’s own speed. The GPS module supplements video information with accurate movement data (vehicle speed, its coordinates, route display on maps).

The DNS EV-200 car video recorder is equipped with a GPS function and allows you to record speed and coordinates and synchronize this data with video. The GPS module is not located in the gadget itself, but in the holder. This allowed manufacturers to expand the functionality of the device without increasing its size. The DVR is connected to the module using a special cable.

Software that allows you to combine video with GPS data is included with the gadget. The video sequence is accompanied by the display of a map section with the ability to change the scale, as well as a graphic image of the vehicle speed.

The DVR allows various recording modes, characterized by different resolutions and speeds. The maximum resolution at a speed of 30 frames/second corresponds to the FullHD format. The ability to activate the appropriate video recording mode is provided to the user and is carried out by selecting the desired item in the settings menu.

The picture quality allows you to see its smallest details, even in low light. In the daytime, it is possible to identify, for example, car registration plates from a distance of several tens of meters. To ensure optimal recording conditions at night, the DNS EV-200 DVR has four infrared spotlights.

The device's camera has an increased viewing angle; the manufacturer claims this parameter is equal to 170°. The almost-full angle allows you to monitor changes in the situation not in a narrow sector, like with conventional DVRs, but throughout the entire space in front of the car. The video quality at the edges of the picture is a little worse, but it is quite enough to recognize details.

The lens focuses automatically, and everything that at first glance is intended for manual adjustment in the device is nothing more than decoration.

In parallel with image recording, audio recording is carried out thanks to the built-in microphone. The sensitivity of the microphone allows you to record, for example, communication with traffic police representatives.

Video recording is cyclical and produced in small files. When the memory resource is full, the oldest fragments are deleted and new ones are written in their place. Video files obtained when the G-sensor is triggered are protected from overwriting.

To store all information, the device uses an external storage device (microSD memory card) with a capacity of up to 32 GB. Such a large memory card resource allows you to save several hours of video and a corresponding amount of GPS information.

The liquid crystal screen located on the front side of the DNS EV-200 registrar is small in size (screen diagonal is 2.7 inches). This is quite enough for the initial acquaintance with the recorded video. A more detailed study of the recording with identification of small parts is best done on a computer or TV. For this purpose, the design of the gadget provides appropriate connectors, and the delivery set includes special connecting cables. It is possible to view the video directly from a memory card via a computer or laptop.

An example of a photo taken during the day in the sun, on a cloudy day and at night.

The autonomous operation of the DVR, due to the small capacity of the battery, does not exceed 30 minutes. This is one of the weakest indicators among similar devices. Uninterruptible power supply is provided from the vehicle's on-board network through the cigarette lighter.

Drivers will no doubt appreciate the ease with which the DVR can be removed from the holder. This quality of the gadget will be useful for those who often leave the car and do not want to leave the DVR in sight.

Setting the time and date of the mirror DVR

Many mirror recorder models come with standard VMS software. It allows you to quickly and easily set the date on your camcorder. To do this, go to the VMS program menu and click on the OK button. This allows you to put the recorder into standby mode.

After this, press the W symbol and enter the settings menu of the DVR program in standby mode. Using the directional arrows, select the appropriate parameters to enter:

1. Numbers;
2. months;
3. of the year.

Similar How to clear the DVR memory card

The same procedure is carried out when setting the time on this device. To do this, you also need to put the recorder into standby mode and press the W button. Then enter the menu and use the arrows to set the desired time. After this, press the key with the W symbol again and exit this operating mode. The final phase of setting the time and date is again also the OK button. When you click on it, the program minimizes and saves the set time to the DVR.

If your mirror DVR runs on Android software, then we set the date and time by copying the actions on the smartphone.

1. Click to enter “Settings” (usually a gear icon)
2. Find the line “Date and time”
3. Enter the required parameters
4. Save and exit the menu.

Summer time

Many models of such devices have a daylight saving time function. It is translated automatically according to a given algorithm. The real-time registration factor for a specific region plays an important role in the case of recording various road accidents. This should be taken into account in order to avoid further confusion and misunderstandings in determining the time of the accident.

Settings failed

Modern video equipment is highly accurate and reliable. Due to some reasons, their software may sometimes crash. In this case, the date and time on the recorder mirror will not be displayed correctly. To avoid this, you should follow some rules:

• Fix the device firmly;
• periodically check the settings;
• correct all changes.

It is not recommended to purchase simple and cheap recorder models. Typically, such models are not reliable and often malfunction. Every day you need to check the compliance of the time and date on the device and, if they change, adjust it in the right perspective. Reflashing the DVR programs increases its reliability and increases its service life.

Exposure metering mechanism

Error e05 for Canon mp250 mp280 printer reset e05

Depending on the set mode, the exposure meter measures exposure and transmits the received data to the camera processor. The processor analyzes the information and exposes the image using software algorithms.

Modes for measuring the brightness of an object in digital cameras are selected either by the photographer during manual control, or by the camera microprocessor during autoexposure.

Automation provides satisfactory image quality in most cases, however, to obtain photographs of a high artistic level, you need to know and understand what exposure metering is and how to use it in practice.

There are several types of exposure metering:

• Spot metering - In this case, exposure metering is carried out on a limited area of ​​the frame (1-5% of the entire image), usually in the center. The brightness of other areas is not taken into account. Thanks to this, the measurement accuracy in the selected area is very high, which ensures its correct exposure. Typically used for photographing a single subject against a uniform, darkened background, when it is required to obtain a clear, high-contrast image. Complex mode used by professionals.
• Center-weighted (average) metering - Metering is carried out within the central area of ​​the frame, limited by the viewfinder markers. The measurement area ranges from 60% to 80% depending on the camera model. This mode ensures optimal use of the most sensitive areas of the matrix, since the ISO of the photo scanner gradually decreases from the center to the edges. The mode is ideal for portrait and reportage photography.
• Partial measurement - Not available on all cameras. This is a mode in which the area of ​​the frame on which the metering is performed (10-15%) is larger than with spot metering, but smaller than with center-weighted metering. It is used when it is necessary to photograph an object, ignoring excessive brightness or, conversely, strong shading of the edges of the frame. In this mode, the detail of the image can suffer greatly (especially at the edges).
• Matrix (multi-zone) measurement - The most common measurement method, which is installed by default in the automatic modes of most cameras. It consists in the fact that the frame is divided into several zones, in each of which the illumination is measured. Then the processor brings all the data together, calculates the average illumination value and, based on it, selects the exposure. In most cases, it provides good image quality, but in difficult lighting conditions it can lead to exposure errors. Suitable for beginners at the beginning of their acquaintance with photography.

Myth 1

Recovering Canon Memory Card Data

If the recorder box says Full HD, this automatically means that you have a portable video camera with an excellent picture in your cabin.

This is wrong. Or rather, not quite like that. This is true for well-known manufacturers and brands. But the valiant “Kulibins” from the Middle Kingdom long ago mastered a wonderful technology called “interpolation”. What does it mean? Only that, in fact, the image in such recorders has a low resolution, and high resolution (HD and Full HD) is obtained by simply stretching the image. Which, naturally, will not be reflected in the best way in terms of quality. The simplest solution is to watch videos on YouTube with an example recording of the model you are interested in before purchasing. Here is an example of shooting Highscreen Black Box Radar plus, obviously with “honest” 1080p.

Review of car DVR and GPS navigator DNS GSV1

The high class of the device is confirmed by the capabilities that this gadget has:

• The Android 4.0.4 operating system allows you to install additional software and enjoy numerous entertainment options.
• Video recording quality – FullHD.
• The screen size (4 inches diagonally) is not a very outstanding characteristic for a navigator. However, for a DVR such a screen is more of an exception than a common feature.
• The presence of a GPS module significantly expands the capabilities of the DVR, adding information to video recording. The user can track the entire route on GoogleMaps and see spatial and speed characteristics at any time.
• Simultaneous operation of the DVR and navigator is allowed. In this case, navigation information is displayed on the screen while video recording occurs in the background.

2GIS is used as a pre-installed navigation program with a detailed display of most populated areas of the Russian Federation. If desired, the user can install other navigation software, either instead of 2GIS or in parallel with it.

All control of the gadget’s capabilities and selection of the necessary functions occurs through the LCD touch screen. It also allows you to view navigation information, captured video files, and multimedia files. The screen resolution of 800×480 pixels allows for comfortable viewing with the ability to detail the picture.

What may cause inconvenience for the driver is the fact that the screen does not allow horizontal rotation, so it may be difficult to adjust for comfortable viewing. Minor rotation is possible only in the vertical plane.

The sound accompaniment of the positioning system is provided using the built-in speaker.

The GPS module, which communicates with satellites, is located in the device mounting bracket. Thanks to this, the DNS GSV1 is small in size and lightweight.

As a DVR, the device has the ability to shoot in FullHD format (1920×1080 pixels at a recording speed of 30 frames per second). The choice of video resolution is left to the user and is carried out from the main menu of the gadget.

Video recording is carried out in cyclic mode, that is, when the memory resource is full, old fragments are deleted and new ones are recorded in this place. The duration of recorded files can be from 1 to 5 minutes according to the user's choice. Video recording is carried out in MP4 format.

This device does not support photography.

The device’s camera based on a CMOS matrix (2 MP, 1/2.7″) allows you to shoot high-quality video in any conditions. Even in the absence of additional illumination, the quality of night photography (or shooting in low light) is quite satisfactory.

The gadget does not have built-in memory, so video is saved to external media (micro SDHC memory cards with a capacity of up to 32 GB).

The DNS GSV1 has two slots for memory cards, allowing two modes of their use:

• Both memory cards are used to store captured video. In this mode, the user has access to a large memory resource, but multimedia capabilities and the use of other navigation programs are not available.
• One memory card is used for recorded video, the second for multimedia files and navigation software. In this case, the data on the second card is protected from possible recording and destruction.

To view the recorded video in detail, the gadget has the ability to connect to external devices. For this purpose, its design provides HDMI and USB connectors.

Unfortunately, manufacturers did not provide the ability to use all the resources of Android 4.0.4. First of all, we mean communication capabilities - Internet access is not provided.

How to reset a car recorder to factory settings

It often happens that a car recorder stops meeting the requirements of its user, “glitches” or behaves very strangely, and the user begins to be tormented by the question of how to set up the video recorder in this case. Either a repair or a factory reset can help here.

How to reset a car recorder to factory settings will be discussed below. It's quite simple - you need to find the desired item in the system settings. Usually it is not hidden deeply, just for those cases so that you can resort to it urgently.

If you have to use this method, remember that the settings are completely reset, and you get a completely “clean” recorder that will not contain any information. Adjustments that have already been made will have to be repeated or revised and others installed.

The optimal option is for someone to reset the settings, who can later return them to their place, i.e. remembers what and how he set it up.

Once the desired item has been found in the menu, all videos have been successfully downloaded and saved, you can proceed to further work. You click on "Factory reset", wait a while (note: the reset may take a long time, be prepared to wait), and when the settings are reset, you are holding a practically brand new recorder in your hands.

First of all, we set the already familiar main settings: language, date and time. After this, you can configure the remaining elements: resolution, quality, day and night photography, sound quality and other data. Please note that here we are only telling you about those vital elements that are installed first. After this, you can configure motion sensors, if any, set navigator functions and camera alerts. How to install these elements on the DVR can be found in the user manual - it provides fairly comprehensive information.

• Model range of Artway DVRs

If resetting to factory settings did not help you and the recorder still malfunctions, there is nothing else to do but send it in for repair.

Only after all the settings have been set, does it make sense to proceed to mounting the device on the glass or the back surface of the rear view mirror - these are the most popular places for mounting a car video recorder. Occasionally, the recorder is placed on the dashboard, but this method is gradually becoming obsolete. Otherwise, you risk ruining the angle at which the recording device should be placed.

A few more settings will be discussed below. Among other things, you can pay attention to several specific settings that will make the picture captured by the recorder better.

Frame rate is a parameter that demonstrates the number of frames that a device can record per second. The higher the value, the smoother the video will be. As a rule, in modern recorders, FPS indicators can vary from 15 to 60.

Viewing angle is one of the most important parameters. The wider the angle, the more you can shoot. Sometimes this is a key parameter, but you need to pay attention to it at the stage of purchasing the device.

Stabilization is another parameter that you need to take a closer look at before buying a navigator. While driving, the car can go over uneven roads and potholes, and the stabilizer will smooth out the image and remove a significant part of the jerks.

Car DVRs record audio and video and save it with audio. Electronic devices record the environment around the vehicle while driving and stopping. The recording resolves controversial issues in case of emergency or incidents on the road. The device works efficiently if the DVR is configured correctly.

What is loop recording in a car DVR?

Car recorders usually support two video recording modes: continuous and cyclic. Continuous mode allows you to record video in one large file. This size can only be limited by the available memory of the device (internal or external). When the free memory is full, continuous video recording ends.

The advantage of this type of video recording is the absence of gaps in the video even for short periods of time. The obvious disadvantage of continuous recording is that it stops when the memory is full. In some cases, the driver is even deprived of the opportunity to quickly reconfigure the DVR to continue filming.

Against this background, the cyclic video recording mode looks much more functional. It has two significant features:

1. Recording is carried out not as a continuous file, but in fragments that are small in volume and duration.
2. As soon as the device’s memory is full, the oldest (by recording time) files begin to be deleted. A new video is recorded in the free space, and the whole cycle is repeated again.

The cyclic video recording method also has its positive and negative sides. The positive aspects include the independence of the fact of shooting from the availability of free space in memory. Video recording will be carried out in any case, even if the memory is full.

A negative aspect of cyclic recording is the inability to save videos of long duration and volume. Only the most recent small files will be saved.

Some DVRs (especially older models) are not able to provide continuous video when recording cyclically. This refers to gaps in the picture at the junctions of fragments adjacent in time to recording. Modern DVRs, as a rule, do not have this drawback. Fragments are recorded in such a way that the recording of each subsequent file begins when the recording of the previous one has not yet finished. It is this overlay of video files that ensures that there are no gaps.

The duration of fragments during cyclic recording, as a rule, does not exceed ten minutes. There are no standard values ​​for the duration of video fragments, and each recorder manufacturer sets them independently. Setting the time during which one fragment will be recorded occurs in the DVR settings. The user can choose the duration that he deems necessary.

Operating the DVR in cyclic recording mode allows you to implement another important and useful function for safety. We are talking about protecting video files from being destroyed or overwritten as a result of the operation of the G-sensor (or shock sensor). This sensor monitors the position of the vehicle in space and the smoothness of its movement. With any sudden changes in these parameters, the sensor marks the video files that are being filmed at the moment, thereby protecting them from possible destruction. The driver does not have to worry about the safety of video files and at the same time he has full access to them.

When saving fragments in the DVR memory, they are assigned names containing numerals in the order in which they were recorded. This ensures a quick search for the desired location in the video if you need to watch it.

The cyclic recording method is most popular among car owners. It provides uninterrupted recording of events into memory of any size. In addition, the safety of video files received in emergency traffic situations is ensured.

In this video you will see a live example of this function on the device.

Important setting in car DVR Exposure

One of the most important settings on a car DVR that allows you to get a high-quality picture is exposure. Incorrect exposure can ruin video frames, regardless of the ambient lighting conditions in which they were taken. The video may be darkened or, on the contrary, overexposed; problems may appear both throughout the entire frame and in a separate section of it, and so on.

What is exposure in a DVR, and how does it affect video quality? Exposure is a setting that allows you to change the amount of light that falls on the camera matrix and actually forms an image on it.

In clear sunny weather, a lot of light enters the camera lens, and if the amount of this light is not reduced, the picture will most likely be too light, even faded. At night, unadjusted exposure will result in overly dark frames. There are several ways in which you can adjust the flow of light.

1. Changing the amount of time light is exposed to the camera sensor. This is the so-called shutter speed, that is, the time during which the electronic shutter of the DVR camera is open to form one video frame. It is clear that the less time the shutter is open, the less light will fall on the matrix and vice versa. Therefore, the brighter it is outside when shooting, the shorter the shutter speed should be.
2. Changing the size of the aperture, that is, the gap in the lens through which the light flux hits the matrix. A larger aperture also provides more light passing through the camera lens.

As a rule, in car video recorders, exposure adjustment does not imply separate adjustment of shutter speed and aperture. The exposure itself is adjusted, and the parameters of both shutter speed and aperture change accordingly. The exposure level can vary from the minimum value, which is recommended to be set in sunny weather, to the maximum value, used in low light conditions.

An important factor affecting video quality is the characteristics of the camera matrix on which the image is formed. These are its dimensions, number of pixels, sensitivity to light flux. Naturally, these parameters cannot be adjusted during operation of the DVR; each matrix has its own characteristics.

High-quality matrices from well-known manufacturers have high sensitivity and consist of a large number of dots (pixels). This ensures the possibility of high-quality shooting in any conditions, both in low and excessive lighting.

Recently, some models of DVRs are equipped with the WDR function, which does not directly affect exposure, but improves video quality by changing the exposure time when shooting one frame. When the WDR function is activated, the DVR makes two copies of each individual recording frame: one version of the frame with a short shutter speed, the second version with a long shutter speed. In the final video, both of these options are combined, and the resulting picture will be practically devoid of the shortcomings of individual frames.

Setting the exposure is very important to get truly high-quality video. The driver should make the necessary changes to its adjustment for any changes in external lighting. It is quite possible that to obtain high-quality video you will have to experiment with exposure settings for a particular DVR.

Exposition

Exposure in a DVR is one of the important settings of the device. The device does not spoil the resulting video frames if it operates within the range of the adjusted amount of light falling on the surface of the recording module mirror. The picture is formed depending on the intensity of the rays, which is one of the conditions for a high-quality image.

Whether you are choosing the parameters of an expensive device or setting up a Chinese DVR, the amount of light must be sufficient to convey small details. Shooting requires adjusting exposure depending on the time of day. Night recording turns out dark due to insufficient lighting, and in sunny weather, blinding rays lead to blurred and faded pictures. Details are not visible, and the material on the DVR turns out to be uninformative.

Follow these steps to adjust exposure:

• change the duration of exposure of light rays to the mirror;
• set the aperture parameter;
• use automatic adjustment if such a function is provided in the device.

The duration of the open shutter in some device models is not adjustable, so the user selects only the exposure. The driver specifies the parameters of the surrounding environment before setting up the DVR, and the gadget sets the optimal recording parameters. The sensitivity of the matrix also affects the quality of shooting.

A lower exposure will darken the image, but a small amount of grain will allow you to see the details you want when lightened.

The situation cannot be resolved in the case of a frame illuminated by rays, the processing of which is ineffective. A value of 1.7 is optimal for high-quality operation of the device in different lighting conditions.

If you want to buy an AutoPASS E6 radar detector, see the model review

The AutoPASS E6 radar detector is an inexpensive Chinese radar detector, its cost is about 20 dollars. At this price, the device has all the standard functionality: it catches in all ranges used in Russia: X, K, Ka, the scale is expanded due to the Ku frequency, which is exotic for our country. To prevent the processor from being overworked, it is better to immediately turn off everything that is not in use. In addition, the detector responds to short shots from Ultra-X, Ultra-K and POR radars. To prevent vigilant highway patrol officers from detecting the presence of this device in your car, it is protected from VG-2 and Specter scanners and direction finders. This must be taken into account when traveling abroad.

What we can thank the Chinese engineers for is the use of a particularly sensitive VCO waveguide, which ensures good reception of all systems. However, according to reviews, the device reacts to everything, and even switching from Highway to City mode does not help. It is also noted that frequencies are not always displayed correctly on the LED display, which may result in another fine.

The Chinese were not pleased with the high-quality laser receiver; the optical lens covers only half a circle of 180 degrees in the direction of movement, and radar lasers hitting the back will not be detected. But nevertheless, the reception range outside the city is more than two kilometers; in the city limits this value decreases.

Additional functions include four-level adjustment of display brightness and signal volume, which will definitely come in handy in a city where there are a lot of false positives. The device is attached with a suction cup to the glass or with Velcro to the dashboard. Do not forget about its correct installation, so that the road is visible to the lens and horn antenna, and there are no foreign objects between the radar detector and the glass.

This device is one of a kind: at a low cost it has good characteristics, although in the city it will constantly disturb you on business and idle time. We can recommend it to novice drivers who adhere to the rules and rarely exceed the speed limit.

If you like fast driving on city highways, then it is better to buy some more expensive analogue. With a high-speed driving style, it will pay for itself in a few days.

Myth 6

If the registrar captured any incident, the filming will become direct evidence in court.

And again, this is only partly true. To begin with, it is desirable that the shooting be carried out at a frequency of at least 30 frames per second. Otherwise, the result is a video with noticeable jerks, which maximizes the likelihood of refusal to attach the video to the case

You should always check that the date and time set are correct; inspectors pay attention to this first. At the scene of the accident, it is advisable to have your watch, the latest issue of a magazine, or other information that will serve as authoritative confirmation of the time of the incident in the frame.
