Does this CCTV cam look a good buy for £180. inc vat?

Is low (12 volt) better than mains ?

There will be no difference - one will simply have an internal power
supply and be bigger.

If you want good 'dark' performance, ignore colour and get an infra-red
sensitive B&W one - with an IR light source it will give excellent results
in the dark and decent in daylight.
