The long road to IP video standards

Together with my european counterpart, Gerard Otterspeer, we wrote this article (http://www.securityinfowatch.com/Cover+Focus/the-long-road-ip-video-standards) for SecurityInfoWatch.com about the standards.

Simple plain English, and touches on both ONVIF and PSIA, as well as IP cameras, encoders and DVRs. The specifications themselves are technical and low-level, yet the benefits for the world are very high level and simple. In doing the research for this article I wanted to add something to the relative void of information in-between.

Reality Check for SecurityInfoWatch.com

I was asked by SIW to be blunt and contraversial. They didn't have to ask twice. Hope you enjoy this article as much as I did writing it.


Understanding RAID

I wrote this white paper to try and turn RAID mumbo-jumbo into plain English. It goes on to explain how Bosch's global storage partner, NetApp, does 'RAID 5' and 'RAID 6'. It's important to understand the differences, especially with RAID 6 (RAID DP in NetApp terminology) because without it you will start losing video as drives sizes continue to get bigger. Maybe RAID 5 is perfect for your needs, but it's always helpful to know what you're not getting by not upgrading one more level, especially when the disk array itself is the same cost.
