H.265 is the latest iteration of compression standards that are based on reducing temporal redundancies in video feeds, or areas of similarity between frames. It has a number of enhancements as compared with its predecessor, H.264, that help it further reduce the bit rate of stream, and although it represents the market direction of video compression formats, there are some drawbacks to adopting this technology now.  


H.265 began to be adopted in about 2015 and started to gain a good deal of attention in early to middle 2016, according to Brian Carle, director of product strategy, Salient Systems, Austin, Texas.

“It is recognized as the direction of compression technology in the video surveillance industry,” Carle says. “When IP cameras were introduced to the market, the compression widely used was motion JPEG because it was a relatively simple process, and the CPU and the chipsets on the cameras were not powerful by modern standards. When the CPU technology became more powerful, cameras began supporting MPEG4, which was a huge advance. Then H.264 became the next standard, and now we can see the market moving in the direction of H.265.”

Carle says the market’s shift in this direction is a result of a perception — a correct perception — that using H.265-enabled products will save dramatically on camera bitrate, which translates into reduced bandwidth consumption for sharing video, and reduced storage consumption for retaining the video.

He estimates, based on the history of other processing technologies in this industry, that H.265 will be the gold standard for at least the near future. “We’re probably looking at a five-to-seven-year lifespan before a newer technology starts to become relevant in the industry.”
