Hi Rodrigo
The UK Home Office SDB produced a good docuemnt back in 2003ish detailing percentage of what FOV you require to achieve ceratin outcomes. Check out their the UK Home Office Scienetific Development Branch web site.
I also use DRI (Detect, Recognise, Identify) with percentage of screen size. There should be plenty of similiar info around, as I am out of office at the moment and do not have access to my documents.
Hope this gives you a pointer.

Subject: CCTV "field of view"?
Dear all,
Does anyone know of any good/easy reference to guess an average "field of view" (FOV) for outdoor security cameras? Or is this not possible at all?
I realize that a combination of the kind of lenses and microships that different cameras have, result different FOVs (there are calculator for this: http://www.sweeting.org/mark/lenses/cctv.php), but I wonder if there is anyway to tell an average measure (in projection). I am surveying private cameras looking at public spaces and wanted to have an idea of how their FOVs can be drawn up on a map.
Any help, at all, would be most welcome.
Cheers,
Rodrigo.
