Serious George - Reccomendations on a home alarm system? Hi all, does anyone out there have a suggestion on an (realitively) inexpensive home alarm system. I don't need it to be wired to a security company or the cops since I live in an apartment building with lots of nosey neighbors, but a friend of mine's apartment has been hit a couple of times recently and it made me want to be a bit safer with "my stuff" than I had in the past. I have a cat, so motion detection is out, but I'd like to get my windows and front and back doors on a (hopefully) wireless system and I'd like to keep it cheap (under $200?). Thanks.
