The 4 million+ cameras in the UK statistic which has been floating around for about 10 years now was extrapolated from two streets in Wandsworth and was only ever really media bait. If you believed all these statistics the number of cameras in the UK would have dropped by more than half (over the past 10 years), since the last large scale estimate was under 2 million.

The UK government doesn't employ vast numbers of people to watch the live output of the minority of CCTV cameras they do own. The state owned CCTV is almost never used in a proactive sense. You can probably safely commit most crimes in full view of a CCTV camera in the UK. If someone reports you or you leave obvious evidence of the crime the CCTV tapes will be reviewed.
There is a massive difference between the man power requirements of analysing video footage compared to analysis of text.
