We’re Complete Security Systems, one of the largest independently owned, full service security and fire alarm companies in New Jersey.
Our story begins in 1983. Back then, founder Chris Mosley ran a one-man operation out of his toolbox. Today, we’re one of the oldest and largest security providers in New Jersey and the only company to be awarded the prestigious NJESA Dealer of the Year for 3 years.
We look after your home and business like family. After all, we live and work here, too. We have been family owned and operated for over 30 years and have a stake in protecting and ensuring security for our community. On any given day, you might find three generations of the Mosley family working at CSS.
We’re proud of our record of trust. Thousands of customers trust us for protection, detection and response—from high-end residential clients to some of New Jersey’s largest commercial and industrial facilities. We also provide service to religious organizations, non-profits, municipalities, schools and more.
