2nd Edition Snippet: Video Compression… H.264 The Solution?

In order to take advantage of the benefits of IP-based systems, security professionals must understand the nuances of IP video. There are two major issues relating to IP video (and more specifically megapixel video) that need to be addressed.  They are the limitations of bandwidth and the fact that high-definition digital video data requires greater amounts of storage/recording space.  The key to striking the right balance comes down to one critical factor – compression and how it is controlled or more appropriately how it is “managed”.

The emergence of the H.264 standard is significantly changing the demands of megapixel video on bandwidth, and consequently, storage utilization. For this reason, the limitations are becoming much less of a factor.
