A lot of episodes would have been a lot shorter had they just had cameras on board the enterprise.
Edit: For all the people talking about the whole 'Computer, Where is (person)' - That is just tracking. There are multiple times in The Next Generation where an incident happens (murder or something else) and they have no idea who did it. If they'd have just had cameras they would have solved it easily.
