H.264 codec is the most recent standard for video compression, the technology applies tp Digital Video Recorders also known as DVR. This codec was developed to reduce demands for video storage and bandwidth. H.264 compression uses up to 50 percent less bandwidth than MPEG-4 to transmit images of the equal quality and characteristics. With substantially lower bit rates, H.264 also uses significantly less storage to store video compared to other standards. DVRs with H.264 allow you to transmit video at faster frame rates and with less storage requirement.
Although H.264 offers significant benefits and is a giant leap in video technology, the extra complexity of the implementation comes at extra cost, usually requiring additional processing horsepower from your DVR. When selecting an H.264 DVR.
