You're going to have to get it further astern and if at all possible lower down to get get the view you're looking for. I'd suggest getting the camera and setting it up in a test stand, five gallon bucket full of sand or rocks and a 2x4-8 in it to mount the camera to. Alternately a 2x4 clamped to a step ladder.
The 5MP camera is on a 1/2.7" sensor and won't perform really well at night unless there's a good amount of ambient light for color or IR for B&W. Either the Dahua 5442 or the Hikvision are the ones to seriously consider. Bother are 4MP on a 1/1.8" sensor which is a very good combination for low light. I seriously doubt any camera, within a reasonable price range, could maintain full color at night in that location. If you really want to see further at night I'd use auxiliary IR lights. As an example I have a rather large one for the back yard here. It lights up the entire back yard with IR so the cameras are seeing out to about 200-220 feet with pretty good clarity and decent quality video. You will find that the ratings from manufacturers on these kinds of IR lights are just a tad on the optimistic side.
Be aware that both the Dahua and Hikvision will need to be "tuned" in terms of shutter speed, gain, brightness, contrast and so on for your location. If left on "auto", default setting from the factory, they will both produce amazing video at night until motion occurs. Then you'll just have a blurry, ghosted image of something happening. The shutter, at night in particular, needs to be set no slower than 1/60, 16.66 milliseconds, and preferably higher to insure good motion capture.
