It will be more cost effective to use video balun with Cat5e cables, we did installation for almost 1800ft (approx: 600m) with Analog camera, it works well, the only thing you may need to do is to provide power with adaptor next to the camera. Video signal through Cat5e can go that much distance, but the power didn't go that long. Therefor, you need power plug next to camera and put in 2A adaptor for the camera. In reality, total cost of Cat5e + power cable is not much cheaper than using IP solution. If you can convince client in such a way, choosing IP solution will be better solution for it.
