To balance the need for HD surveillance and corresponding storage and bandwidth cost, and to keep pace with the development from H.264 to H.265, Uniview spends enormous efforts to exploit HEVC coding standard, and finally invented the patent coding technique U-Code. The combination of U-Code and H.265 is the unique technology – Ultra 265. Ultra 265 is an end to end solution which can save up to 95% storage space and 75% storage cost, bringing great convenience to users.
Unlike conventional video compression technologies
which tries to reduce storage costs by sacrificing resolution and frame rate indiscriminately, U-Code chooses to use ‘IRP’ (Intelligent Region Perception) to detect motion in each frame. Hence, scenes containing interesting information could be preserved while the other relatively static area such as lawns, white walls could be squeezed to save storage.
In order to reduce bandwidth, U-Code stretches GOP (Group of pictures). Meanwhile, it uses V.I. (virtual I frame) to ensure that media has a key frame that contains critical information so that the NVR can run the frame accurate search and quick playback – this technology is called EF tech, i.e., ‘Enhanced Frame.’
By combining U-Code and H.265, Ultra 265 can squeeze up to 95% bandwidth and storage space.
Ultra 265 – brings great benefits to customers
Under the same configuration, Ultra 265 costs only one hard disk to store the same video record which needs four hard disk under H.264, saving 75% storage cost. Customers would benefit from both storage cost and deployment cost from Ultra 265.
Moreover, Ultra 265 retains the image quality enhancement brought by H.265, reduces the image distortion caused by code compression to a great extent, optimizes image blur, trailing smear and rough of stroke edge, and improves the accuracy of VCA. Besides, Ultra 265 also breaks the bottleneck of HD resolution. It enables customers to make full use of super HD surveillance products like 4K under current bandwidth and storage deployment. Ultra 265 is the best choice for customers to enter into the era of Super HD.
