Image compression reduces the file size of video images to optimize bandwidth while streaming surveillance footage. The most common compression technologies for IP network cameras are Motion JPEG and MPEG-4. H.264 is the latest compression technology that significantly reduces the file size of high-quality video images. High Efficiency Video Coding (HEVC), also known as H.265 and MPEG-H Part 2, is a video compression standard, designed as a successor to the widely used AVC (H.264 or MPEG-4 Part 10).
