About Us

SMS Security Systems, LLC. is a family-owned business that has been serving Northern New Jersey since 1985. From our Headquarters in Caldwell, we provide quality installations and superior service in all aspects of the low voltage industry. Our Company’s size allows us to provide a higher level of personal service and attention to detail that the national companies just can’t match.

As an authorized  GE Security Pro Dealer we have been selectively chosen from hundreds of security installation firms for our attention to detail, clean installations and superior customer service and support.

SMS is a proud member of the New Jersey Burglar & Fire Alarm Association. Our founder Scott Stellfox has served as Northern Region Vice President and on the Board of Directors in the past. Our installers and service technicians are trained by the Electronic Security  Associations National Training Program, and they attend continuous in house and manufacturer’s training. A well-trained technician ensures each client the very best in trouble free installation and service.

We offer free estimates and security consultations. Please contact us.
