I have an autopage and it goes off if you look at it funny. With a fresh battery in the remote its got about a 200 yard range. That plus the Nissan Titan horns under the hood are pretty fucking loud. The only bad thing is loud cars, trucks, and thunderstorms are a bitch because I have to turn the ignition on to disarm the system completely. If I dont it just re arms itself in 30 seconds.
