H.265 video recorders

H.265 codec

— recorders supporting H.265 codec.

A codec is a technology used to compress video; without such compression, the footage would have an unnecessarily large volume. Specifically, H.265 is one of the most advanced modern codecs (as of 2021). Compared to its predecessor, H.264 (AVC), this standard provides twice the compression ratio for the same quality (and therefore better video quality for the same file size). This, in particular, makes it possible to reduce the volume of recorded materials and increase the efficiency of their transmission, especially over low-speed channels (such as mobile networks with unstable coverage). And the maximum video resolution supported by this codec reaches 8K.

Specifically, in the case of registrars, H.265 support allows you to at least record video in this compression format — which helps save space. In addition, for network (NVR) and hybrid (HDVR) models, this feature is also required to work with IP cameras that also use this codec. To view footage on external devices — these devices must also support H.265; however, problems with this nowadays occur very rarely, mainly in individual low-cost or outdated media players. And when playing on a computer, there is nothing to worry about at all: modern PCs and laptops support extensive sets of codecs, and in extreme cases, the missing ones can be installed separately.
