What is the H 265 standard? The difference between H.265 and H.264 in CCTV
The HEVC standard, or H.265, is a video compression standard. In fact, one minute of uncompressed video takes up about 7 GB, a lot of space; Meanwhile, two hours of video increases this amount to about 840 GB. Therefore, compression and bandwidth are important issues for storing and transmitting information in video surveillance systems.
HEVC standard or H.265 in Hikvision camera is actually a codec that can minimize the amount of data storage without losing image quality by encoding video files. This standard is a set of MPEG compression systems with the same performance. In this technology, the background of the image is saved by default and only movements are recorded in it.
The H.264 standard is a common video compression standard and the predecessor of H.265. This format is used in most DVRs and NVRs and, like HEVC, it reduces the storage size while maintaining the image resolution.
What is the difference between H264 and H265?
Files encoded by H.265 are two times smaller than H.264.
The encoding speed in HEVC is much faster and the bandwidth usage is reduced by about 50-70%.
Also, H 265 technology can display better image quality by reducing the bit rate by 50%.
PLAYBACK possibility of playback of images in H 265 with higher speed and more continuity than H 264.
Currently, H.265 is considered the best compression technology and recently the new generation of recording devices are equipped with this standard.
