Unfortunately there will always be dishonest people that will take anything that isn't anchored in concrete... and even then some try to take those too. The days where most people showed respect to eachother and eachother's property is long gone. Those that are truly honest are an extremely small percentage of the population these days.
If I were putting up a trail cam I would do like others have mentioned... use a ladder and put it in a locked, secure box up high where the average passerby either won't see it, or can't get to it.
