200 feet might be a bit of a stretch without some intense IR illumination. Most cameras respond to near IR around 900 nm wavelength. Light-intensified cameras operating in the visible can easily do this without illumination, i.e., so-called starlight scopes, but they are rather pricey and would have to be fitted to a CCD camera. The second-generation scopes are available on the surplus market, and maybe later generations too. The current state-of-the-art generation is unobtainable unless you are fighting in a war zone, or perhaps are a law enforcement officer.
There are also real IR cameras operating in the mid-IR around 10 to 12 μm wavelength that need no illumination, but these are quite expensive and most require cryogenic (liquid nitrogen) cooling of the detector to obtain a good signal-to-noise ratio. I saw one in Dallas TX about thirty years or so ago, built by Texas Instruments for a government project, that could see for miles in total darkness. Our company was acting as an intermediary for a foreign government who wanted to mount these puppies on gun boats to interdict smugglers. It featured video auto-tracking (you just used a joy stick to place a cursor on a target) so a servo-equipped gun mount could track and aim at targets automagically. Pretty awesome stuff back then. I am sure the technology has improved a lot since then because you can now buy un-cooled microbolometer cameras that are almost as good while responding to mid-IR wavelengths.
Are you concerned that whoever you are looking at will see a near-IR illuminator? Some folks (I am one of them) can see an IR LED in dim light. And if you have a cell phone camera they show up like headlights in the night. Try aiming an IR remote control at your cell phone camera to see what I mean.
I use a wireless CCD camera with IR LED illumination to keep tabs on the inside of my detached garage both day and night, but the wireless transmission range is very short, about fifty feet or so. I used to hook it up to a VCR in my living room and let it record overnight, but it became very boring fast-forwarding the next day through hours of recordings. So I gave that up. There are solid state disk drives that do a better job of recording, and there is software video motion detection that triggers the recording only when the scene changes. You should Google some of those key words to see what is currently available to see what you can afford.
