With the advent of H.264, all the components are now in place. H.264 is an open, licensed standard that can reduce the size of a digital video file by more than 80 percent compared with Motion JPEG and by as much as 50 percent compared with MPEG-4 Part 2.
The improvements in image quality brought on by high-definition TV have generated widespread demand in the consumer market. A similar trend is already unfolding in traditional video surveillance markets. HDTV-compliant network cameras deliver a resolution, color representation, aspect ratio and frame rate that are in accordance with international standards. This makes them an appealing solution for surveillance environments requiring exceptional visual clarity.
