Reasonable prices for our services If you have an alarm system that is not currently being monitored, one of our experienced technicians will come to your home or Business and reprogram any existing system for small fee. As one of the most well-respected alarm companies in Atlanta we also know the importance of keeping our prices reasonable. We charge just starting at $15.00 per month for our alarm monitoring services. If you are in need of an entirely new control panel, Brian Security Systems will install a brand new control panel and one free touch pad and tie in all the devices on your existing alarm system.
