Idea about alarm and security
bdmac97: Video/cameras is pretty easy these days since there are a variety of wireless, networked cameras that provide their own web access so you can view them anywhere in the world.It's been awhile since I was researching alarm integration but form what I remember it did not sound trivial.  There are modules that you run your alarm system through that then connect to a control server via serial connections (although may be updated now?).  Here's a pretty good forum for researching that kind of stuff: http://www.avsforum.com/avs-vb/forumdisplay.php?f=162
