Plextek develops new techniques to bring clarity to CCTV surveillance

Plextek has developed new codecs to address the issue of poor image quality that has become synonymous with many wireless CCTV surveillance systems. Current video surveillance techniques work well over wired networks, but wireless links add noise and latency that standard techniques such as H.264 and JPEG2000 fail to cope with. The result - intermittent and blurred images which make it difficult to identify perpetrators. Working closely with customers, Plextek have developed a new simplified codec that is based on JPEG2000 and includes enhanced compression techniques to improve wireless video performance.
