Simple good quality camera's

Hi,

I need 3 simple but good quality camera's on bnc (meaning not to expensive)which i will be using with an LFG card. There needs to be an infrared option on it. Colour is not necessary but welcome. Res about 640x480.

Any suggestions?

you pay for what you get.
the cheap cctv cameras often have very poor image quality.

you will have to see what is available in your local market and test what is acceptable for your application.
