Does anyone have experience of the cctv cameras which do colour in daytime
and b&w at night?

"A REVOLUTIONARY night-vision system developed for the Dutch military makes
night-time video images look as clear and colourful as those shot in broad
daylight."

Do a search for "starlight" cctv cameras. These can give colour images
down to 0.001 Lux AIUI. The Chinese company making these has some very
impressive pictures on their website. The technique is to use a Sony HAD
CCD image sensor, cool the chip to reduce noise and then reduce the
shutter speed down to say 1fps. (this speed is adjustable). Not cheap,
but good for commercial cctv.

Mintron was the maker I was thinking of.
