Indeed, even the CCD ones are often 1-2 lux minimum though. At the lower
end of the market at least.

There are some with decent low light performance, but they're very
expensive.
eg. Mobotix:

They also have some [even more expensive] megapixel day/night cameras.

Give it a couple of years though, and I reckon both the price and the
specification will have improved quite a bit.
