Hi hyrumster2,
I am using a 20 ft cable connected to a powered usb hub with no issues even though it seems like this length is not recommended. 30-50 feet may be a little far without a powered extension as wwestphal suggests.
What sort of structure are you planning to mount your camera on? Is it on a tree or under an eve or something? the cameras are surprisingly tough in my experience as far as temperature is concerned. I have my c-4000 camera in the mountains where the temperature fluctuates from max 100 in the summer to min 15 in the winter. My "housing" is a ziplock bag with a hole cut out for the lens

It has been going for 1.5 years with no issues. I also sent you a private message that you can check in your inbox.
