Screen type
The sensor is a key element of any digital camera; it is from it and from signal processing technologies that the quality of the resulting image primarily depends. In this case, the type refers rather to the brand or brand of the matrix; it is usually indicated if the recorder is equipped with a high-quality sensor that is noticeably superior to most solutions on the market.
One of the most popular such options is
Sony. The specific characteristics of the matrices (
IMX179,
IMX222,
IMX291,
IMX307,
IMX317,
IMX322,
IMX323,
IMX326,
IMX335,
IMX415) may vary, but anyway, such a sensor is a sign of a high-end DVR.
In addition, there are models equipped with matrices from other manufacturers —
Aptina,
OmniVision,
Samsung(GalaxyCore),
Sandvik. Such solutions are generally considered to be simpler and more democratic than Sony — both in terms of price and functionality. Nevertheless, Samsung has a lot of developments in the field of electronics, and even such r
...elatively “simple” sensors are usually more advanced and of higher quality than “know-names”.
Another manufacturer that produces fairly high-quality matrices is Panasonic. Such sensors are not as widespread as those described above, but they are still found in video recorders, including pretty advanced.Processor
Model of the processor used in the dashcam
The term "video chip" is used mainly for devices with classic capabilities, "processor" — for advanced models with an abundance of non-standard functions. However, anyway, we are talking about the same component — the main computing unit, the characteristics of which directly affect the capabilities of the recorder as a whole. Knowing the model of the processor, you can find detailed data on it and evaluate how satisfied you are with a device based on such electronics. Of the most advanced modern chips, one can name, in particular,
Ambarella A7L,
Ambarella A12,
Novatek NTK96655,
Novatek NTK96660 and
HiSilicon Hi3516.
Quad HD
The maximum resolution and frame rate of video recorded by the recorder in the Quad HD standard.
In terms of detail, the
Quad HD standard sits between Super HD and Ultra HD. It does not have a specific standard resolution, but most often in video recorders there is shooting with a frame size of 2560x1440. However, even such models are relatively few; and more specific values like 2688x1440 are used even less often. There are also quite unusual options — for example, a square frame 1440x1440.
As for the frame rate, the higher it is, the smoother and less blurry the video will be, the better the details on moving objects will be visible, and also the more space the footage will take up. However, in the case of Quad HD, a frequency of 24 fps or 30 fps is usually used, and the difference between these speeds is generally unimportant.
