Navigating video compression standards
When it comes to managing video compression in an IP camera network, it's a balancing act between maintaining high-quality images and reducing video file sizes to optimize network bandwidth and storage capacity. There are a number of video compression technologies available, and today's IP cameras usually come equipped with several options to achieve the best possible compression ratios for any given surveillance application.
Motion JPEG - This compression standard is one of the most common available with network cameras. Using Motion JPEG, the camera presents video as a series of individual JPEG images. The frame rate can be easily adjusted and any frame rate at or about 16 frames per second is considered full motion video.
MPEG-4 - With MPEG-4 the bit-rate of images is lowered to meet the level of image quality required for a specific surveillance application. Like Motion JPEG, this compression standard is commonly found with most IP network cameras.
H.264 - H.264 is one of the newest compression standards available. H.264 drastically reduces the size of image files without compromising quality. With this compression technology the benefits are numerous including reduced storage and bandwidth costs, higher resolution and frame rate, and improved megapixel camera performance.
