We combine state-of-the-art audio technology and human intelligence to verify a threatening event before we call the police. That way, the police know it's not just another false alarm and they roll, fast and in force. Sonitrol enjoys an average 3 ½ - 4 ½ minute response time throughout California; police typically roll two or more cruisers to a Sonitrol call. So, we catch 'em! Sonitrol is the only system that offers 100% coverage: floor to ceiling, wall-to-wall. Other systems protect doors and windows, leaving unconventional entry points unprotected. Sonitrol the only security system that can detect all criminal intrusions, no matter where they enter.
