RVT 0 Posted November 5, 2013 I'm a 20+ yr vet of the access control / security industry, working for the largest company that makes access control equipment for the mini storage business. Seen the industry go from having a few B&W cameras attached to a switcher, to long term video tape machines, and then to DVRs and Megapixal IP cameras. We've changed a lot in 20 years!
