Simple Analytics .... Intrusion Detection

Hi everyone, I'm about to install a system, ~30 cameras in total. The cameras are to be temporary secured onto the side of some wooden hoarding - whose total perimeter is ~600 metres.

The cameras are to go apx every 30 metres and pointing then in from the hoarding at an angle of ~30 to 40 degrees. In this way ...we're someone to climb over the hoarding and into the site the cameras video analytics would pick them up.

I've always used analogue cameras combined with redwall 3020 pir detectors connected to a dvr made a company called Teleeye. I would continue to do the same were the site apx 3 times smaller.

So I'm going down the ip route.

I have in mind to buy a load of maybe Hikvision cameras which apparently are able to see 50m in the dark and do have some limited Analytics on board. The model number is DS-2CD2232-I5.

The camera is a 3mp bullet type. Should the analytics be no good it also comes with an alarm input - so could install them with PIRs if needed

I'm not looking for particularly advanced analytics.

The site concerned is a construction site. The camera simply has to pick people up within 30 metres or so of it. Ideally it will ignore foxes...but no great expectations on that front.

An alternative purchase is the Hikvision DS-2CD4A26FWD-IZHS. Same make of camera but triple the cost and perhaps with more effective analytics.

I hope to be able to "get away" with the first option.

I've been assured it will reach 50 metres but I'd be perfectly happy if it made 30m. If it could some how pick up anyone walking past it and with less false alarms than mere motion detection I'd be happy. I'm not after left baggage alert or counting people etc....but the ability to register and pick up a human.

I'll also be using a 32 way hikvision nvr connected to a monitoring station using either the sentinal or immix Platform.

Any suggestions most welcome.
