dslr camera helicopter image
Q.
Answer
There are two types of infra red camera
Ones that work by recording reflected infra red light - either from normal daylight, or from an infra red light shone onto the subject. All you need is a camera with an Infra Red filter. Regular DSLR camera's can be fitted with these, or converted specially to record such images. Even film cameras using special Infra Red film can record images lit by reflected Infra Red light.
And then there are cameras that record thermal infra red emitted by warm objects in total darkness - like the kind you see fitted to police helicopters. Basically the sensor in the camera is sensitive to thermal energy emitted by the subject. Often these are referred to as thermal imaging cameras.

Answer
Well first of all that was takin from a helicopter, so you would need a little more than a camera. But, given you have a chopper, you could probably take that with any low end DSLR. Im really not sure you are going to be able to do it for under 400. A lens that wide alone would cost you at least 400. You would need a Canon XTi or XSi, or Nikon D40 D60 or D70, and a ultra wide angle zoom that goes from about 10-20mm or something like that. You might be able to do it with a point and shoot, but I dont think it would look quite as good.
