Jjas, you still have to put cameras where the deer are unless you're baiting. You still need to know where deer are going to cross. I'm sure if you put enough time into it and had many many cameras you could really figure a deer out, but that same person is going to have strategic food plots, man made funnels, and a high tech compound or crossbow to finish the job. Cameras changing hunting I don't know for sure, but they have added a facet to scouting that wasn't there 20 years ago. As far as the actual hunt I believe food plots have affected that the most.
You make a good point about food plots, funnels and the like. And while food plots will draw them in, cameras placed in that plot or in the other areas you talked about will tell you what is using those areas and when it's happening.
And that makes patterning that "special" deer a whole lot easier.
