Author: IPVM Team, Published on Dec 19, 2016

However, starting in 2013, analog cameras with HD resolution started shipping and, now, just a few years later, HD analog has become a significant force in the video surveillance industry.

In this report, we examine AHD, CVI and TVI, including their most recent 3rd generation advances, compared to IP cameras.
