SONIA Security, since 1981, has been a leading provider of security products and services to homeowners and businesses throughout New Jersey and the New York Metropolitan Area. All of our security products are state-of-the-art and backed by the leading manufacturers in the field including burglar alarms, fire alarms, video surveillance, and card access systems. SONIA can also provide you with access to professional security monitoring services that can offer you 24-hour rapid response in the event of an attempted break-in or intrusion.

It'd be easy for us to just say "choose us!", but instead, we'd like to share 10 reasons why we think (and our clients think) you should select S.E.M Security. You'll notice we have more than 10 reasons listed, that's because based on your feedback, we are proud to say that the list continues to grow! Other alarm companies have come and gone, but S.E.M Security Systems has served and grown with our community for over 30 years. When trying to select a company that will provide service and support for many years, you can be assured that S.E.M Security has clearly earned the long-term trust and confidence of its customers.
