Glossary: H.264 Video Compression Format

H.264 (or MPEG-4 part 10) is an emerging standard in IP video and IP CCTV.  It is a method of video compression which can dramatically reduce the bit-rate of live streaming video without any reduction of image quality.

Side-by-side, the size of the data streaming from a camera using H.264 will be up to 80% less than MJPEG and up to 30-50% less than MPEG-4. This means that bandwidth load across the network is significantly reduced when using H.264 compression and storage costs will be lower when recording CCTV footage.

The downside of H.264 compression has been the increased hardware costs due to greater amounts of processing required by the camera. This has made the technology available in only the very high-end network cameras so far, but this is changing.  With the recent launch of the Axis M10 series we are now seeing the introduction of H.264 in entry-level IP cameras and we think that H.264 will fast become the standard video compression format of choice for all network cameras in the years ahead.
