Two 8 camera mom & pop retail facilities: 100% analog, over the past five years.
Why? My opinion: the paupacity of clear information within the security industry.
Initial facility was set up by ADT in 2010. They recommended and installed analog. Nobody ever went wrong hiring IBM, right?
For the second facility, we reached out to a well regarded local security company who recommended Mobitix and came in at about $18K. Analog, while obviously less capable, came in at $6K. What absolutely wonderful capabilities would I get for that additional $12K?
Then I joined IPVM. There's an amazing world of information out there, for layman and professional alike :)
