Monocular Camera for swing angle detection and obstacle avoidance

edit

Hi

I have a Machine Vision for a crane. So must meets the requirements for swing angle detection and obstacle avoidance from the crane (by the distance of around 40m). So, I need some high quality monocular or stereo camera that should be able to detect the swing angle and obstacle at a distance around 40metres and meet the other requirements like dynamic range. Please, can you suggest any monocular or stereo Camera that meets such requirements?
