We have had This security company for 3 years now and have Consistent problems with their camera systems to the fact that they are consistently down. I have even paid for the upgrading of their system only to have significantly more down time. What good is a home security system if it is consistently going down? Most recently I have had technicians out or resolve/fix the problems only to have more problems. When I called recently to communicate my concerns, I was promised a call back. Guess what? No call and it has been a few weeks now. When you call, Mr. Doyle answers the phone (albeit a digital comment) and promises great service. Mr. Doyle, could you please help us out? We have a lot invested in your systems.
