dvr / nvr's aside, i could get a far better and clearer image from a 1/2" CCD with a decent lens than most IP cameras doing the rounds. and dont get me started on I.R
Its not so much the technology itself im ranting at, but the **** that is flooding the market, its a race to the bottom of the barrel. So unless its Avigilon quality its landfill fodder.
A.I in real life use does one thing. that is it cuts the search time looking for an incident. That and it saves on installing detectors and the associated cost in that. The only true useful advance is thermal is available to all and AI is only really accurate (for detection) when used with thermal.
Backtrack--Ok, ANPR is good.
