Untrained buyer is quite difficult to navigate in a large number of different DVR models, offered by stores.
To make a successful purchase and spend money wisely, it is necessary to study the information about these devices, decide on the functions you need exactly in this gadget.
Manufacturers produce DVR models with different characteristics and capabilities, in different price segments.
Quite a large niche in the production of quality devices at an average price occupy companies from China and South Korea.
When buying such gadgets there is no need to overpay for the brand, but the quality of assembly and components are inferior to the flagships.
When choosing a device you should take into account the main parameters:
Video recorders for the car according to their design features can be divided into:
In terms of functionality are divided into:
The main parameter to pay attention to when choosing a device is the screen resolution.
Normally Full HD (1920x1080) and Super Full HD (2304x1296) resolutions are used. HD resolution (1280x720) gets an image of not very good quality, especially in low light.
The angle of view of the camera lens at 90 degrees allows you to capture what is just in front of the car.
A camera with a viewing angle of 120 degrees or more captures what is in the other lanes of the road, on curbs and sidewalks.
Professional DVRs may have cameras with an all-round view. Please note that a viewing angle of more than 120° may cause frame distortion at the edges.
The number of DVR cameras installed in different parts of the car determines the completeness of the overview of the surrounding situation. The characteristics of each camera must be taken into account.
The camera installed on the rear window of the car allows you to increase the field of view, as well as help when reversing and when parking.
When you turn on the parking mode, the image from the rear camera on the display becomes a priority and avoids errors and hit-and-runs. The disadvantage can be considered as additional wires in the cabin.
The presence of additional cameras leads to an increase in the price of the device and the complexity of the installation.
The video recorder is most often connected to the onboard network of the car through the cigarette lighter.
The use of a rechargeable battery makes it possible to record video with the engine off.
Usually the battery capacity is small, 150 to 600 mAh, and allows you to record from 10 minutes to 1 hour. This time may be enough in case of an accident to have time to make a video recording. Most often, the battery-operated standalone mode is activated if the car's electrical system was damaged during the accident.
Most often, lithium-ion (Li-Ion) or lithium-polymer (Li-Pol) batteries are used for the autonomous work of the device.
Shock sensor (G-sensor) controls the position of the car in three planes and in case of sharp changes of parameters creates a file which is protected from erasure.
It is better to set such sensor to min sensitivity, because otherwise it will react including to the passage of the "lying policeman", and to hit a pit.
Availability of anti-radar in DVRs is an additional option, added by the manufacturers. For this purpose, it is necessary to enter information about the combined database of traffic cameras and radars of the traffic police into the memory of the device. The actual database is downloaded to the SD-card.
When the data recorder receives GPS data, it is compared with the database of cameras, and the driver receives information about the need to reduce speed in advance..
The database needs to be timely updated to get the latest information, but still such devices are not absolutely reliable.
DVRS can be combined with radar detectors In one case. This saves space in the cabin and makes the device a universal driver's assistant.
Combo-devices are of two types depending on the antenna used in the antidradar:
Combined devices with more reliability fix radar complexes, but do not protect 100% from false alarms, especially when driving in a big city, where a lot of additional interference.
There are three types of mounting for the device installation in the car:
The data recording in the video-recording devices is made to an external memory card, which is to be bought separately.
Some devices may have a small built-in memory, which doubles some of the fragments or continues to record if the memory card is completely full. The capacity of the memory card is usually 32 - 64 GB, which allows you to place a large number of video files on it.
VCRs use Secure Digital Memory Cards (SD and microSD) as standard, which are also compatible with smartphones.
Some models have two built-in memory card slots for quick copying of the recording in case you need to hand over an SD card to the traffic police inspector.
If the DVR supports WI-FI, it is possible to use cloud storage to save the recordings. The storage is provided by the manufacturer of the device.
The quality of recording in the dark depends on the design and software features of the device.
In some models, manufacturers have installed infrared illumination, giving the opportunity to shoot in complete darkness. The image in this case is monochrome and not too clear.
Changing the exposure for night shooting in automatic or manual mode improves the quality of the picture.
There are models of DVRs that do not have a display. But devices with a screen are much more convenient to use. Such a device is easier to set up - the menu is displayed on the screen, you can immediately see the field of view of the camera when you install it. The display allows you to immediately resolve many controversial issues on the accident by viewing the video at the scene.
LCD displays are usually used in DVRs..
The screen can be combined in a single unit with the DVR, can be detachable or have a flip and swivel device.
Facilitates management of the gadget touch screen, the diagonal of such a screen is usually slightly larger.
The most important part of the device is the processor, on which the work of the device completely depends. Processors used in DVRs have a simpler set of commands, smaller size and power consumption than in computers. They are called System on a Chip (SoC).
Video recorders mainly use single-core processors, the performance indicator of which is a clock frequency - the number of operations (clock cycles) performed in one second..
To perform the necessary functions the clock frequency of 400-700 MHz and higher is used.
The architecture on which the processor is built is the most important factor.
Designed and used by 4 families:
The best known manufacturers of chipsets for video recorders include:
At the same time, companies that are rapidly gaining in popularity occupy a prominent position in the market:
Additional useful functions which can be supported in devices:
