Built by a guy who hates the runaround

David Dunoff launched DSD in 2012 after seeing too many security companies overcharge, underdeliver, and leave clients stranded. He believed people deserved systems that actually worked and a team that actually showed up.

Thirteen years later, that's still the mission.
And it's working (literally).

You build it, we'll secure it.

WHAT WE DO (AND DO WELL):

Commercial security builds

Residential low-voltage setups

Full-service design, install, maintenance & monitoring

security material

Small and mighty

(and mighty good!)

WHO WE ARE

We're intentionally small, and that's exactly how we like it. This means you get a security partner, not a faceless corporation. When you call, we actually pick up the phone. We know our clients, so you'll always talk to someone who understands your needs, respects your budget, and shows up exactly when we promise.

Low in Voltage. High in Everything Else.

This isn't just a catchy phrase; it's the core of our promise. We specialize in low-voltage security solutions, meaning our systems are efficient, safe, and discreet to install. But don't let "low voltage" fool you into thinking we cut corners. In fact, we go high in everything else that truly matters:

We stay ahead of the curve, offering cutting-edge security features that keep you safer.

David's greatest innovation was streamlining and unifying our security infrastructure. He didn't just make it more manageable and reliable; he transformed it into a cutting-edge system that keeps us safer and well ahead of the curve. The transition was smooth, and his expert guidance made the entire process easy and remarkably effective.

Our low voltage systems are designed for consistent, long-term performance and peace of mind.

Opening a new business, it was important for us to ensure security and safety not only for our customers but for our staff. DSD Security was able to provide our security system, cameras and even remote options for us to monitor our building offsite! When we moved locations, they were extremely helpful in upgrading our systems and are always available to problem solve when needed. We would definitely recommend DSD Security!

Kutest Kids Early Intervention

You'll experience a genuinely personal approach from consultation to installation and ongoing support. We take the time to understand your unique needs and tailor solutions just for you.

In a world where it’s hard to find reliable vendors, David was always reachable and willing to take the time to break everything down and explain it clearly. That made a huge difference for us.

— Gabriel Rahmani

With us, you get the best of both worlds: the efficiency and safety of low-voltage technology, combined with a superior experience in every other aspect of your security.
