It's a good security system. Check the price though. Most of the goodies are optional. e.g. 3 stage perimeter sensor and ignition disable. Some good features are it's range, it says good to half a mile, but my pager still went off at about 1 mile. Another is the rotating alarm code, so it can't be scanned.
I would suggest having it installed, but if you want to do it yourself, there are instructions on the web for doing it. I just don't happen to be a wiring kind of guy :lol:
