High-efficiency video coding (HEVC), also known as H.265, is a video compression standard, one of several potential successors to the widely used H.264 or MPEG-4.

In comparison to AVC, HEVC offers about double the data compression ratio at the same level of video quality, or substantially improved video quality at the same bit rate.

Most new GRUNDIG cameras, and all its embedded recording devices, make use of H.265 high-efficiency video coding.


Ultra HD security cameras have been in production for a while but were not immediately adopted and widespread because they require excessive transmission bandwidth and enormous storage capacity. The problem can be solved by using H.265pro+ encoding technology, which uses an average of about 87.5 % of the bit rate of H.264. As the bit rate of the recorded video material is greatly reduced, the bandwidth and storage costs are also reduced. H.265pro+ is based on the standard format H.265/High Efficiency Video Coding (HEVC). With H.265pro+, the video quality is close to that of H.265/HEVC, but reduces the required transmission bandwidth and storage capacity due to three key technologies: predictive coding, noise reduction 
and flexible bit rate control. It shows significant improvements in bandwidth reduction, data storage efficiency and the analysis of video content
