How to choose a quality driving recorder?

/in /by

If you have selected a reliable brand to buy a driving recorder, you need to focus on analyzing some product parameter before you purchasing a driving recorder, it seems like shooting angle, resolution of picture, compressed format, caching, and we also need to know whether the video can be closed manually; whether it can record a video normally at emergent situation; whether no jamming to other electric products and whether purchasing with card etc.

Shooting angle

The shooting angle is 100 degree for ordinary driving recorder, which is basically  enough to make sure shooting the two lane side of vehicle. Of course, bigger angle is better, and the expense is more too.

Resolution of picture

Generally video resolution  is 1280 * 720, which can promise take a clear picture for license plate in ahead, and license plate of side lane will be a little vague in the driving recorder. In addition, the photosensitive ability of SMOS chip in driving recorder and the quality of lens’ glass is connected with the shooting effect at night.

Compressed format

Most of driving recorder use compressed format H.264 .  Without a good compressed format but not losing frame, which require bigger storage capacity and higher reading speed of memory card. The size of 1 minute fragment of 720p resolution H.264 compression is about 60MB. In terms of drivers, it is helpful to choose a reasonable recording interval and volume for providing accident evidence in time, and 1 minutes as a interval time is appropriate.

Cache

A bigger volume of cache can bring smoother video and better memory card compatibility.

Emergency video

If there is a important video you want to leave, and the driving recorder also need to shoot video next,  which cause the important video will be deleted at the next time, for solving this situation, it occurs a emergency video design for keeping a special video,  so that if you just press a key manually, you will force the video to be saved without being automatically deleted when the card is full. Automatic emergency recoding video is the use of gravity sensor. It will automatically protect this video without being automatically covered and deleted during monitoring  a violent vibration on car, this function will be useful for vehicle collides.

Shielding measures

In order to decrease the cost o products, the copycat products always do not take any shielding measures and without strict test for their products, which will cause this products disturb some electronic products, such as GPS navigation  , remote control, audio, tire pressure meter, and driving computer, etc.

Whether purchasing with card

Driving recorder video with high definition picture,  always has a big volume up to hundreds MB per minute, so that there will be a strict request for reading speed of memory card, and  I advise driver purchase a superior card, because the slow speed card driving recorder is easy to be out of order.

What is CCD rearview car camera system?

Firstly, I think if you want to know about the CCD rearview car camera system, you should understand what CCD is and what CCD rearview car camera is, then you will realize more about CCD rearview car camera system.

What is the CCD?  CCD ( Charge-coupled Device) is a semiconductor device, which can convert optical image into digital signals. The tiny photosensitive material on the CCD is called pixel, and more pixels on the CCD means higher resolution of picture. There are many arranged photodiode on the CCD, which can sense light and transform light signals into the electric signals, then CCD convert electric signals into digital picture signals though enlarging the external sample and analog data.

What is the CCD camera?  The CCD camera focuses the image of the object on the CCD chip through the lens, then CCD accumulates corresponding proportion of charges according to light intensity, these charges will covert into video signal under the control of video sequence, thus you can watch the video when the video signal is connected with monitor or TV.

The principle and composition of CCD rearview car camera system

The principle of CCD rearview car camera system : CCD rearview car camera system is an improvement from original reversing radar. The car camera mounted on the rear end of the car,  take the picture and send the video signal into car display near the driver’s position though transmission line, which can make the driver see the environmental obstacle on time around the rear end of the car and expanding the view of driver, also increase the safety efficiency and make sure driver have a safe reversing action.

The composition of CCD rearview car camera system: car display, reversing camera and transmission line.

Generally speaking, the CCD rearview car camera exist for drivers could having a good view behind of the car so that they can have a safe reversing and avoid to injury passerby .
