Overall, the project went well. We dealt with one sales person - one point of contact for questions and issues from beginning to end . . . very good. The presentation of the product and services was impressive. The price was a little steep but we got the whole kit and caboodle - not one opening to the house was left unprotected. We also got their internet access/notification package (awesome convenience) and cellular backup (great peace of mind). The system works as advertised and we have been very pleased with it. We've had it now for about 6 months. We did have two minor problems though. The first is that one of the garage door sensors was not installed properly and it scraped the garage ceiling when the garage door opened. This should have been tested and fixed before the installer left the premises. They did come back promptly to fix the issue. The second problem was that, in six months, I?ve had to replace my key fob twice due to malfunctions ? I think it was a battery connector problem inside the fob. My wife has had no problem with her key fob, however. The primary suggestion that I have for CPI Security, and the only issue that I have with the system, is that when my wife leaves for work at 6 am, if she arms the security system with her key fob as she is leaving the garage, the interior keypads beep for about 30 seconds before the system arms ? these beeps wake me. Your key fobs should be able to arm the system silently. Alternatively, she could arm the system from the downstairs keypad and, with a 30 second delay; she could jump in the car, open the garage door, back the car out and close the garage door before the alarms sounds. This would avoid the 30 seconds of beeps but she doesn?t want to be rushed every morning. So, I get to hear beeps. Sometimes I can go back to sleep and other times I can?t. This should be an easy fix CPI ! A tip for buying a security system. Be sure you put your keypad(s) in a location where you will typically be most of the time. We had one keypad installed at the bottom of the stairs where we enter the house from the basement. The other keypad was installed in the bedroom at the end of the hall. Well, if we are in the kitchen and want to open the back door to go to the deck and grill some hamburgers, I must either go to the bedroom at the end of the hall or to the bottom of the stairs at the basement to turn the alarm off. Alternatively, if I can find my keys, I could disarm the system with my key fob, I guess. In hindsight, I would probably put a keypad at the top of the stairs also - which would be near the kitchen. Thought this may help someone.
