Extreme weather, and/or vandalism

I have serious concerns about the doorbell cameras and outdoor cameras. What happens when exposed to extreme cold or heat? What about vandalism where the person or persons, especially wearing a face covering, damages the cameras/doorbells with a hammer, bat, etc, and/or spray paints the peephole of the door and camera? I know of several forum reports all over the internet of these types of issues? Also, what about hacking??? What say you?
