ethernet based camera

I am looking for an IP or GigE camera. it needs to work over long cable runs,must be good quality colour, work at night (also colour), manual exposure and gain control, must have an SDK. fast video not important (grabbing frames at 1 a second only)

so far i have looked at cameras from allied and imaging source and they look very sound very good on paper. i was wondering if anyone here has much experience with these or can recommend something else?

the IP cameras (i.e. with inbuilt webserver and POE) i have looked at haven’t been all that convincing so far but i am open to suggestions.

I am testing the Allied GS1020 at the moment with not great result, but I may not know enough about the camera yet. I will post if I get better results using it.
