A Primer on Electronic Security for Schools, Universities & Institutions

Blog Site for 2nd Edition Discussions & Reference Material

Archive for October, 2009

“A Primer on Electronic Security for Schools, Universities & Institutions” Second Edition is under development for release in Spring 2012.

The Primer, originally published in 2006 by Henry Homrighaus Jr. , is designed to assist educators, engineers, security personnel, and suppliers to address and resolve the issues of potential terrorism or other acts of violence or disruption in our educational institutions. 

The Second Edition updates the Primer to include the multitude of changes the security industry has seen in the last three years such as the convergence of Security, IT & Communications and the maturity of the digital video market segment.  To update the Primer, the author Henry Homrighaus Jr. added co-authors Frank J. Davies and Greg Bernardo. 

Together the team of authors has launched a website to promote the upcoming Second Edition.  The website includes a blog which encourages discussion on topics found in the First Edition Primer and seeks to identify additional topics for inclusion in the Second Edition.  Digital (IP) video (which was still fairly immature at the first writing) is the first category of discussion in the blog focusing on the topic of H.264 compression.

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.
