Sonitrol has been the trusted name for protecting businesses, schools, and homes in North America, with a combination of human know-how and the latest technology. Our system is so sophisticated that we sometimes catch criminals before they gain entry to our customers' facilities. The cornerstone of our success is our unique impact-activated, audio-based intrusion detection system. Our technology allows us to verify the threat posed by an alarm event before we call the police. That way, we minimize false alarms, create a faster police response, and actually apprehend the criminal!

Ultimate Security was established in 1992. We cover all of Northern California installing remote digital video camera systems, burglar alarm systems, fire systems
