I think what he's saying is that instead of the cost of an actual policeman on the beat, it's 'cheaper' to stick cameras everywhere and have people sat somewhere watching what's happening and then reporting it.
I'd call that reactive policing as opposed to proactive.
Thanks for that.
Another advantage is that the control room can resource an incident effectively if they can see it. Previously we might get a call to 'big fight, West Street' and would be reluctant to send a foot unit on its own. So we'd detail a car, perhaps move another nearer just in case, until we got a report as to how bad it all was.
With CCTV we could see precisely the seriousness of the incident, either just the foot unit if that was all that was required, or perhaps every unit if the public were at serious risk.
The CCTV controllers were a very keen lot and would often generate work, being the originators of an incident.
In the 'old days' the beat bobby was the eyes and ears of the job. I have to say that they were better, much better in fact, but with the current reductions in officers - one current PC reckons that numbers are down by almost 30%, with promises of it getting worse - a foot unit is an expensive luxury.
I reckon my time on the beat was the best in my 30 years. Information, meat and drink for policing, flowed in. One bloke running a cafe had precons for manslaughter. He was a very pleasant chap who was, remarkably one might think, very pro police. He got me a commendation just by recognising a chap I'd asked him to keep an eye open for.
Those days are all but gone.
CCTV is all we can afford nowadays, but it is a very effective tool.
However, there is a major privacy issue, certainly with the data, which hasn't yet been addressed.
