blue iris ftw. sunba 20x cameras can be had to provide a lot of dynamic ability you wouldn't see in any traditional camera system.

on a side note to prewiring a house:

You can also do it when you reroof a house. run the cables in places where you're not apt to nail (like on top of valleys), to a centralized place on top of the roof where they descend into the attic space. Then shingle over the roof as you normally would. cat5,6,7 etc. doesn't care about the heat, so long as it doesn't have uv exposure it'll last as long as the shingles do or longer.
