Our Story
Established in 1989 as a sole alarm company serving the Southern California market, Signal Security Systems has since evolved to provide varying services to our clients such as access controls, data cabling and telephone systems. To reflect our newer and added scope of services, we have a new d.b.a. as ThreeSigmas. Since our inception; we have consistently incorporated better quality, value and service into every project we have undertaken for our customers. Providing design, consulting and installation services to our commercial, government and residential clientele, we utilize the latest technology in our security systems and data networks for your specific application and requirements. We are committed to providing the highest quality and value to our customers which has been our primary focus since we began.
No matter what size and at what stage you are in development of your facility, we can customize the system that you need for your business or organization, whether it is access control, security or data networking, we are there for you at every step and stage of growth.
We specialize in the design and installation of custom residential intrusion detection systems. Our alarm systems include the ALARM WINDOW SCREEN which is attached to your window like a normal insect screen; these screens offer unprecedented protection for perimeter security, because they detect a break-in attempt BEFORE the intruder gains entry into your house. Ask us about this feature and the many other custom options we offer in our security systems.
