Most people dont pay attention to others going into someone elses pits or traailers at races because from what i have seen, most racers are open to helping anyone that needs it or will let other peopke use their stuff, especially scales and tools at races. The only people i could see actually paying attention to someone going into another persons trailer or pits is if that trailer or pit belongs to a friend of the person who noticed. I know at the races iv been to, you see alot of racers sharing their scales and stuff with other racers and allowing others access to their trailer, and just about everyone leaves their trailer and pit open when they go to the track to race, leaving them vulnerable to theives who can walk in at any time and take whatever they want.
I also like the idea of the camera's or at least a game camera in the trailer or watching over your pit area while you are on the track or watching races, that is a really good idea. There is no better proof than picture or video of someone in the act taking your stuff. I do also believe it would be hard for anyone to just walk into another persons trailer and take scales without being noticed by at least one other person, but at the same time i can see how if someone did see the person take them, they probably thought that person had asked and had permission to borrow or use the scales.
