Matrix resolution at the registrar may be in the range from 0.3 to 12 megapixels, and the resolution of captured - from 640x480 up to 1920x1080 pixels.A higher resolution gives a detailed picture, which will see the smallest details, such as number of the car in front.Which is better to buy an inexpensive DVR?It is necessary to proceed from several parameters.For example, the number of frames per second.The figure is more, the smoother the video will go from view, and there is no jerking when removing pictures of what is happening at high speed.In modern devices of this indicator lies in the range 15 K / s - 60 K / s.A good indicator - 25 / s and higher.So for Full HD that figure - 30 k / s, and for HD - 60 f / s.Another question - what firm DVR is better to buy?What to look for in the first place?
Angle.This parameter determines how much data will fit horizontally in the frame.Thus, with the angle of 90 degrees DVR zasnimet region within a windshield.If the figure of more than 90 degrees, the image is partially fit and what is happening on the side of the car.But it is worth remembering that at a high angle distortion may occur at the edges of the screen.Straight lines (poles, buildings) will appear curved.So what better to buy a DVR?

What DVRs best in terms of optics?In addition to these factors, the quality of the image is influenced by camera optics, the physical size of the matrix, its sensitivity.To become better acquainted with the future purchase, worth a look, it removes the device under different weather conditions.This is possible when the seller provides the ability to exchange and return for a certain period after purchase.But better, of course, immediately decide what is best to buy a DVR.

mount options, usually under the windshield.As a means of attachment to the body there is a special registrar sucker, powerful enough to hold the unit while driving.However, it happens that the suction cup is not quite of the quality and for the better retention is necessary to resort to the help of glue.Some models mount can be mechanically using a special clamp.
also in the housing can be positioned in GPS receiver to track the coordinates of the location of the vehicle.But this addition is not necessary.
about quality issues "pictures»
quality video recording - one of the most difficult aspects, find a unique solution is not easy.Which is better to buy the DVR to get the clear picture?Resolution recorder - one of the most important parameters in this topic.The recordable pictures can be Full HD or HD.The size of the video at a resolution of HD - 1280x720, while Full HD - 1920x1080.Devices of the first type relate to the budget resolution, and the second - a more expensive.But what's the complexity of the issue?Even DVRs Full HD resolution can have different optics, compression and decompression algorithms, and therefore remove these devices will also be different.
as registrar
To learn about the quality of a device, many are guided by user feedback, expert opinions.Do not bypass this tradition and automobile video.Especially popular are videos on YouTube, captured this or that model.Of course, some familiarity with the device to receive these rollers can be.But it is worth remembering that most of the commercials - advertising.They overstated quality, are examples of the daily shooting in sunny weather, without any interference.And if you have already set ourselves the aim to get acquainted with car DVR, you better pay attention to the notes made by motorists that they provide without any treatment.
According to some reviews, many cheaper models have problems with brightness adjustment.When a bright light strikes the windshield (counter lights, sunny weather in the winter), the registrar does not have time to change and the resulting video turns out overexposed or, conversely, too dark.This fact is worth paying attention.In this regard, you need a good think about what is best to buy the company DVR,
also need to say a few words on the night scenes.So often when demonstrating the seller shows a picture, taken in the daytime, and buyer are satisfied, but at nightfall, when sunlight is absent, the video turns darkened, and dismantle it something it becomes very difficult.What are the best recorders, do not create constraints as for lighting?
If time watching videos is not, you should at least take into account the fact that it is not necessary to acquire the model with non-standard resolutions.In addition, you should choose a device with Full HD, better to overpay for quality, than to suffer with poor quality video.Before buying also worth checking that the picture had no delays, no noise, no braking.About
write cycle and the length of the fragment
Since the recorder memory is limited, and the record should not stop, it serves as a solution to overwrite old data.That is, until the memory is free, video is recorded in the normal mode, but as soon as it is full, a new record begins superimposed on the old from the start.
record is not a continuous flow.It is divided into files of a certain duration.Most models record breaks into fragments 1, 2, 3, 5, 10, 15 min.There are devices that write everything in one big file, but it's not the best idea.In some recorders you can manually change the duration of the stored video segments.But there are instances where this option is strictly prescribed in the code of the device.It is worth to explore on purchased DVR ratings any better?
What length fragment choose?It depends on the circumstances.Mode 1 and 2 minutes, you can just fold.Dig into a pile of one-minute files, enjoy below average.If the trip taking place in the city limits, the mode 3 or 5 minutes should be fine.If the trip is going to be prolonged, for example, a tour of interesting places, you can choose 15 minutes.Then he will see and remember.
What else should I keep in mind when choosing DVR
There are a number of additional features are worth paying attention to.
GPS sensor.It may serve as a good, if you know the pitfalls.The sensor captures all the contacts from the movement, and can later be viewed with special software (Google Earth).It warns of approaching the speed camera.Notifies about speed.On the last detail.Some DVRs do not have a function to turn off the speed sensor and video constantly are superimposed figures.When traveling in the general urban traffic with a speed of 70 km / h lower speed will not be possible, and the sensor will warn about excess, and, worst of all, the excess will be recorded on the record.So when you buy should pay attention to the ability to disable the speed sensor.
further about what is best to buy Chinese DVR?It also should carefully examine all the functions.
G-sensor
The purpose of this function - catching emergencies and recording in special tracks (10 seconds before the crash and 20 seconds).The signal for the operation of this sensor is a sharp jolt as the collision of an accident.However it is necessary to adjust the sensitivity of the G-sensor, exposed to the minimum, otherwise it will work on each "speed bump" your DVR.
Reviews: Which is better?
reviews online rather contradictory.Many complaints about the poor quality of shooting at night.Consumers say that Chinese products are often in no way inferior to European originals.
LED backlight
As a rule, issued in the form of a plurality of LEDs around the camera.Their task - to help the camera to capture images at night.But in practice by highlighting this little use.Not the best marketing move.
Antiradar
DVRs The new models have a supplement as "radar" radar detector.The DVR is a better - with a radar or not?Many talk about the benefits of such a device.This radio signal, which is the way DPS inspector with the police radar.
Mount registrar
Made in a bracket with suction cup.If necessary, you can detach the suction cup and stick in the other car.Tightly stick is not necessary.But the brackets with suction cups also are different.The main thing is what is expected of sucker - secure grip, then the recorder will not fall off when hit in the first counter hole.Holder also should be easily rotated to change the angle.For example, when you stop the traffic police inspector, the camera will need to turn toward the door to remove the conversation on video.This is worth remembering when buying.
