The latest standard for video compression is the H.264 codec. 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 same quality. With substantially lower bit rates, H.264 also uses significantly less storage to store video compared to previous standards. In a nut shell, DVRs with H.264 allow you to transmit video at faster frame rates and increase your archive duration.

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, be sure to choose a manufacturer or supplier with a proven track record.
