Debunking Arecont Rep's Megapixel vs Analog Calculator

Author: John Honovich, Published on May 09, 2011

One of the most common and dangerous fallacies in IP video surveillance today is pixel / resolution equivalency. For example, many vendors will tell you that a 3.1 MP camera is equal to 10 analog (or SD IP cameras) because a 3.1MP camera has 10 times the number of total pixels. CV Reps, an Arecont rep firm, has taken this to a dangerous level by emedding this fallacy into a spreadsheet.

In CV Reps's spreadsheet, you "insert the number of megapixel cameras in the project. You can then see the number of analog cameras required to deliver the same resolution/total pixels to the project as well as the estimated cost of both. " The image below provides an excerpt from the spreadsheet demonstrating their assumption that (1) 3.1MP camera is equivalent to 10 analog cameras.
