Wireless system may end up costing you more for the installation since you need extra components(maybe a hundred bucks).
The security company will give you very limited discount if you have the rough in, for my case, they only give me $20 even though I paid 300 bucks for the rough in...of course, if you don't want more construction work after you move in, rough in is a good idea...
