Protection Concepts came to our home a year ago and installed a new system in our 30 year-old house (we had just purchased) that was never wired for a security system. The service techs were courteous, knowlegdeable of their product, and took care to clean up the wires and debris from the drilling and installation plus they were timely and didn't overlook anything.
As far as monitoring, we've had a few false alarms we've accidentally set, and the monitoring station has been great and very patient in taking care to confirm our identities within what seems like 3 seconds! The price can't be beat whether you are doing the basic system, or the top of the line, it is the best in the metro Atlanta area. The owner and sales team will not oversell to you and really have your protection, and the safety of your home as top priority. I highly reccomend Protection Concepts for all your home security needs. A big dog helps too, but Protection Concepts has 911,fire/police/EMS on speed dial!!
