Ultra 265 compression greatly reduces the size of your digital video files without compromising the image quality (compared to other compression standards, such asH.264 & MJPEG). Ultra 265 is a stable, proven compression technology, which offers unbeatable recording picture quality while at the same time saving you valuable hard drive storage space.
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 will stretch 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. We call it EF tech, equals to "Enhanced Frame".
By combining U-Code and H.265, Ultra 265 can squeeze up to 95% bandwidth and storage space.
Under the same configuration, Ultra 265 only costs 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 the advancements list above, 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.
