Видеорегистратор Whatever you may say, but car DVRs for motorists are one of the most useful devices.

Only not each motorist can make a right choice and get the device which is most suitable it on quality and parameters. Therefore it is worth understanding everything attentively.

Producers

Here it is worth allocating that, and, above all demanded devices from China and Korea are the most popular. Of course, there are devices and more high-class of Japan, the countries of Europe and America, but their price is too high, and on functionality they it is not better than "east" analogs. The Korean and Chinese video recorders differ on a stuffing and functionality. Respectively, also the price will fluctuate.

Fastening

Quality will be rather good if the good 1,3 megapixel optics is used. The main shortcoming is weak sensitivity of some models, especially during shooting in a night-time. There are, of course, devices with the resolution of 320 on 240, but for the serious purposes it is better not to use them, after all at approach it will be impossible to consider even number of the car which is ahead, and after all it is very important factor at accident analysis.
Permission of HD and Full HD is the most popular today. Record speed in this case will be to 30 frames per second. Quality of record of such device really magnificent therefore if necessary it will be possible to consider the most insignificant at first sight the details but very important for the proof of innocence.

Viewing angle

For a chamber it is one of the most important characteristics. And often applied corners of 130, 110 and 80 degrees are the most popular. Of course, the narrow viewing angle allows to consider more precisely registration plate of the car going in front, but after all and the most important details can be passed and the review of the next strips will not be available. Therefore the most effective are video recorders which chambers have the review in 120-130 degrees.

ON or software

Usually Chinese devices keep record in avi a format. It is possible to look through such video on any computer or the TV. Video recorders of the Chinese production generally do not write down office information on location and time. Registrars from Korea are capable to keep record of additional office information, thanks to existence of GPS. The necessary set ON usually registers in a memory card which is delivered in a set.

Secondly, in some Chinese models record is kept not in the habitual MPEG-4 format, and in usual MPEG that leads to that memory of the device is filled already through a small period. Therefore it is better to select models in which the format of compression of H.264 is provided, after all only it allows to store long record and continuously its messages if necessary.
Thirdly, almost all Chinese devices at record of video for memory form pauses between rollers which have duration about seven seconds. It is fraught with decrease in value of the device at road accident, after all many data will not manage to be taken.

Conclusions
