Re: Minimum FPS for CCTV system

[Chris Hunter <cjhunter@xxxxxxxxxxxx>]

when I looked at this, it seemed to be mostly a card limitation ...
ie:
'more cards, and higher spec' cards, for more fps ... plus disc-size ...

I also started out thinking I'd need a lot of cameras, but about halved
the number as 'ideas developed ...

mind you, it also seemed the quality of CCTV had someway to go, if
identifying people is to figure in the scheme of things ...

or so it seemed to me ...

then again, CCTV perhaps also has role in motion detection, as part of
HA ... for meeting the needs of people as they move abouti... ie:
lights, sound, TV, and even BG's pictures on the wall ... which might
put the number of cameras up again ...
