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.

Aperture

The aperture ratio of the lens installed in the video recorder.

This parameter determines how much the optics weaken the transmitted light flux. The aperture ratio is indicated by a fraction - for example, f/1.8. The smaller the number in the denominator, the more light the lens can transmit. A conventional model with an f/2.2 lens will theoretically produce a darker image than a recorder with a high-aperture optics of f/1.5.

High aperture ratio is important, first of all, when shooting in low ambient light conditions: it allows you to capture images in the twilight and dark hours of the day without creating additional artifacts in the form of noise. At the same time, when shooting with high-aperture optics, the blurring effect of moving objects in the frame is reduced. On the other hand, the actual quality of the recorder camera depends on many other factors - in particular, the type of matrix, the image processor used, etc. Therefore, the aperture ratio specified in the characteristics is not the ultimate truth - it is rather for reference.

Field of view

The viewing angle provided by the main camera of the DVR. As a rule, it is indicated along the diagonal of the frame, less often - horizontally, because of this, models with the same numbers in the characteristics may differ somewhat in the actual field of view. So if you have doubts about this, when choosing, it does not hurt to find and watch video samples from different models.

Other things being equal, a wider viewing angle allows you to cover more space, but individual details in the frame are smaller. In addition, wide-angle lenses give geometric distortions of the image (however, DEWARP can be provided to eliminate them, see "Functions"). As for specific figures, viewing angles up to 120° inclusive are considered relatively small for modern registrars, values of 121 - 140 ° can be called average, 141 - 160 ° are above average, and the most wide-angle models are able to cover a space of more than 160 °.

Max. memory card size

The largest size of the memory card allowed for the device. This limitation is primarily due to the fact that more powerful hardware is required to work with larger volumes. In addition, there are nuances associated with individual subspecies of cards. Anyway, this value cannot be exceeded: with a high probability, the registrar will either work incorrectly, or will not be able to work at all, or even completely fail.

Most modern registrars support cards up to 32 GB or 64 GB, but there are models that are compatible with more capacious cards — 128 GB or even 256 GB.
