Sonitrol of Delaware Valley: Serving the Business Security Needs for Over a Decade

Since 1964, Sonitrol Security Systems Delaware has been the trusted name for providing home and business security systems in North America, with a combination of human know-how and the latest technology. Our system is so sophisticated that we often 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! No other business security systems can compete with our solution. Serving Delaware, Southern NJ and Philadelphia.

Our sophisticated listening equipment has helped us catch over 155,000 criminals.

Providing Peace of Mind: Unmatched Gurantees

Sonitrol is above all a service organization. Our confidence in our systems and the people behind them is backed by a true Commitment to Service. We know of no other security company offering to stand behind their products and service in this manner. The four key points of this commitment are:


During the first six months of installation of your Sonitrol audio intrusion detection system, if you are dissatisfied for any reason, Sonitrol will neatly remove our equipment from your premises and refund your installation fee – no questions asked. We truly believe that the best way to “think about it” is to evaluate our system first-hand.


If your audio intrusion detection system requires emergency service, Sonitrol guarantees the arrival of a service technician, on-site, within three hours.


If you receive a fine for a false alarm that was dispatched in error by Sonitrol and caused solely by Sonitrol’s audio detection system and not by your personnel, the telephone company or an Act of God, Sonitrol will pay the fine.


If you experience a break-in, and Sonitrol fails to dispatch the authorities, and you have a loss, Sonitrol will pay up to $5000 of that loss. Of course, you have insurance to cover unfortunate events, but at least Sonitrol has “skin in the game,” every single night, with every Sonitrol-protected facility that has a qualifying Sonitrol audio intrusion detection system. Does your security company protect you with the same vested interest?
