Differences H.265 and H.264

Differences between H.265 and H.264

A codec is an encoder and a decoder. An encoder compresses audio or video so it takes up less disk space. A decoder extracts audio or video information from the compressed file. Video and audio compression is a complex technical process, but the basic aim of a codec is quite straightforward:

(a) Reduce the size of the compressed media file as much as possible, but...(b) Keep the quality of the decoded audio and video as good as possible.

What is H.264?
H264 (aka MPEG-4 AVC) is currently a mainstream video compression format. It is widely used in Blu-ray discs, internet sources like videos in YouTube and iTunes Store, web software, and also HDTV broadcasts over terrestrial, cable and satellite.

What is H.265?

H.265 (also known as HEVC, short for High Efficiency Video Coding, developed by the Joint Collaborative Team on Video Coding (JCT-VC)) is a video compression standard whose predecessor is H.264/MPEG-4 AVC. H.265 HEVC ensures to deliver video quality identical to H.264 AVC at only half the bit rate, including better compression, delicate image and bandwidth saving. It Support up to 8K, Support up to 300 fps. It is likely to implement Ultra HD, 2K, 4K for Broadcast and Online (OTT).

H.265 vs H.264: Differences between H.265 and H.264

In general, H.265 has several big advantages over H.264, including better compression, delicate image and bandwidth saving. For more detailed differences, please read H.265 vs H.264 comparison table.

4 pcs 2MP IP cameras for 1 month, stream: 4096Kbps. 
H.264 IP camera need 42G×4×30=5T=1×3T+1×2T, so need 1 pc 3T and 1pc 2T HDD. 
H.265 IP camera need 21G×4×30=2.5T, so need 1 pc 3T HDD only, save at least 1 pc 2T HDD cost. 

Security Cameras in Our Growing Technological Society

Security Cameras in Our Growing Technological Society

Within our rapidly-growing technological society, CCTV Cameras are gradually becoming a larger part of our lives. As security concerns grow in a post-9/11 world, and as affordable security cameras become more prevalent, we are beginning to see the implementation of security cameras not just in homes and businesses, but also out on public streets.

As the prevalence of security cameras becomes greater, privacy concerns also grow: Is it worth sacrificing our personal privacy for the sake of ultimate security? In many areas, you can’t walk a couple blocks without being recorded by a camera. With the increase in public security, many questions have arisen. Although public footage is kept only in the case of an emergency, many people still fear the “big brother” concept detailed in 1984, George Orwell’s famous novel about a paranoid society controlled and monitored by an oppressive government.

But when looking at vast amount of cases where killers, rapists, burglars, etc. have been discovered and apprehended thanks to CCTV camera footage, it’s hard to dismiss public surveillance cameras as invasive. Innocent footage is most likely never seen, and even if someone were to watch you whistling while walking down the street, would it really matter? As long as footage is never abused in any way, security cameras should remain an integral part of our landscape.
