H.265에 대한 쉬운 안내 글 입니다.

High Efficiency Video Coding (HEVC), also known as H.265, is a video compression standard that first debuted in 2013. In comparison to its predecessor, H.264(AVC), it offers on average double the data compression ratio while maintaining the same image quality at the same bit rate.

H.264 is widely used, but just like H.265, took a few years to take off. Since its creation back in 2013, H.264 has undergone 22 revisions up until 2014. H.265, respectively, has had it latest 4 revision in 2016. Due to being owned by various parties under restricted patents as well as having licensing fees that are more expensive than H.264, it has deterred many from adopting the new technology even with its clear superiority. Although as time progresses, H.265 will be the only viable video encoder for higher resolution systems.
One of the main benefits in the security industry to which one would prefer H.265 is storage capacity and costs. The new IP systems that support this video encoding standard boast about the 50% of bandwidth reduction. This includes the costs saved on physical SATA drives and a more expensive router that supports higher bandwidth.

For example:
An H.264 IP system recording 24hrs/day with 16 4MP cameras with a bit rate of 6144 kbps has a total bandwidth of 98304 kbps. With an 8TB HDD in the NVR, this system can record for about 7 days.

An H.265 IP system recording 24hrs/day with 16 4MP cameras with a bit rate of 3072 kbps has a total bandwidth of 49152 kbps. With an 8TB HDD in the NVR, this system can record for about 14 days.


Below is another comparison example between H.265 and H.264:

​H.265/HEVC also supports HD and Ultra HD (UHD) video formats. H.264 lacks in this aspect as it can no longer meet the requirements needed for video encoding for higher image resolution.As customers' demand better and better image quality, H.265 is the video encoder of the future where 4K and 8K UHD will also become the standard in the market.

Again Notice below at the difference in the clearness of the image using H.265 as opposed to H.264.

Consider getting an IP NVR and IP cameras that support H.265 for your next IP job, don't wait to upgrade to the future of IP!
