Try this, http://www.ebay.com.au/itm/HD-SDI-1080P-Full-HD-Box-Camera-2-Megapixel-1-3-CMOS-Image-sensor-/281010620283 it has manual settings, is IR ready and easy to mount. You can get very cheap ultr wide lenses for it and it also does HDSDI OR Composite over BNC, much better than a camcorder with locking BNC connections and it never turns off. With a 150 dollar black magic capture you can get low latency SD OR HDSDI. I have used a few of these and they are perfect for tracking. If you are clever you can also remote the settings but I did this with OF not Izzy. Use a lens calculator to see what you need to use to get the width you need from the right distance. Grab a an IR Lamp and you can do all the tricks from mortal engine (although Izzzy might not pull them off). With all this your are still about the same price as the camera mod and you have some pro (ISH) gear. Best of luck
