Our History

In 1980 our founder, Nick Papanicolaou started installing home security systems in the Metropolitan DC area, while pursuing his Phd in Electrical Engineering at the University of Maryland.

Nick loved experimenting, problem-solving and troubleshooting the latest technology in wired security systems which resulted in valuable hands-on practice with adapting technology.

Even while Nick pursued his physicist career at the prestigious U.S. Naval Research Laboratory, word of mouth referrals continued. Local families and builders started relying on him to provide creative solutions and guidance for custom installation of home automation security systems.

Many times, Nick had to rely on his troubleshooting experience to figure out a fix that would work for the problem at hand. He actually thrives in difficult situations when other contractors say it can't be done, he'll spend hours a day devising workarounds to help gadgets talk to each other.

This is the reputation that builds the Poseidon team. We will always figure out a way.

As technology adapted at record rates, Alex decided to continue the family tradition. By applying his technical degree with his consulting experience at top IT management firms, his first priority is making sure he can find a solution to your project.

Today, the family business continues using the same principles to grow a network of satisfied customers, leveraging electrical engineering skills to build tangible working solutions.

Almost 40 years of experience and still going strong

Excellent full service A/V work and advice. Alex came to help move outlets, hide cabling, and mount an awkwardly shaped WiFi access point. He did a great job. I would highly recommend Poseidon System's service and planning hiring again for additional work in the future.

The team at Poseidon Systems are great! My new home builder left a bunch of unfinished wires for AV equipment and they were able to hook up everything and look very professional. They were on time, respectful, and cleaned up afterwards. Pricing was very good too. Highly recommend!
