Cooling Surveillance Systems

Author: Ben Wood, Published on Jan 29, 2012

An IPVM survey and discussion addressed the topic of “How often, if ever, do you add additional cooling measures to rack/ equipment rooms?” The survey results show that 70% of the respondents replied “0-20% of installs” indicating that it is not something generally addressed or provided by security integrators. However, a recent IPVM update on hard drive failures shows that integrators are experiencing a significant number of hard drive failures due to heat. In this update, we’ll take a look at why cooling is important, determining when additional cooling measures may to needed, and what cooling measures can be added to racks to reduce equipment failures.
