CHELMSFORD, Mass.--A study commissioned by Axis Communications' North American offices here found that an IP-based system of 40 cameras offers a lower total cost of ownership than an analog-based surveillance system. Chris Humphrey, of Chris Humphrey Consulting, based in San Diego, conducted the study. A dozen interviews were conducted with non-vendor industry participants from different regions of the country. Participants provided feedback, validation and cost data in the form of request for proposal responses. The RFP was based on a typical deployment scenario that included a 40-camera surveillance system for a small- to mid-sized school campus, in a greenfield environment with no previously installed system. In this scenario, Humphrey found, the break-even point is 32 cameras. Below that, an analog system is less expensive. The study is available at www.axis.com.
