The builder of our new home offered a security system that was hardwired but mucho $$$. No option existed to pre-wire home for a 3rd party system. We went no security and then had ADT install a full wireless system with integrated smoke and a hardwire fire detector. We paid close to $2K out the door - still about $1.5K cheaper than through the builder.

The wireless systems have battery driven sender units at the door/window sensors so unless you have window covering they might be offensive to look at.

Other than that, and the occasional dead battery, the whole install was painless. I agree with the observation that most alarms are useless against burglers - window stickers and a sign or two probably do most of the "protection" anyway. The system is purely peace of mind for my wife for when I travel plus it (talks) lets us know when a door/window sensor is opened. The whole episode with the Danielle Van Dam/Westerfield murder - sneaking in at night unknown - at least we get some warning.

Monthly monitoring is around $25. Options included the smoke & fire detectors that automatically notify fire dept in hopes of limiting fire damage. Our house is about 95% flammable so I doubt this would help much.

Good luck.
