The security cameras tied in with phones/ipods/ithingys is becoming very common. I know people that have motion detecting and infra red security cameras around their house, with wireless communication with their ipad thing. A few unobtrusive cameras can cover your whole perimeter. I don't know how much these systems cost, but I wouldn't be surprised if the price will drop (or is dropping now) in the near future.
Neighbors are a big thing, if you get along with them. We tell our neighbors when we will be away, they keep an eye on our house.
