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!

Frequently Asked Questions


What types of properties do you service in Bethesda?

Poseidon Systems works with homes, condos, offices, retail, and other commercial properties. From smart home security systems to commercial Wi-Fi installations, each system is planned around the layout, use, and technical needs of your space.

Can an existing system be upgraded instead of replaced?

Many projects involve improving an existing setup with updated equipment, better coverage, or easier controls. However, you need an on-site consultation first to help identify what can stay and what should change.

Do you provide custom smart home systems?

Yes, our smart home systems can include lighting, shades, audio-video, climate control, and centralized access. The setup depends on the property and the features the client wants most.

What is included in a security system installation?

Typically, a home or office security system may include surveillance cameras, alarm components, access control, and remote viewing. The final design depends on the size of your property and security priorities.

Can you improve weak Wi-Fi coverage in larger homes?

Yes, Wi-Fi and networking upgrades can improve dead zones, slow connections, and inconsistent coverage. A better network design supports stronger performance across your entire property.

Do you handle TV mounting and media room installations?

TV mounting and media installations may include display placement, wiring, speaker integration, and control setup. The goal is a clean look and a better viewing experience.

Do you work with businesses in Bethesda?

Yes, we install commercial audio-video, security, and networking systems for offices, retail spaces, and other business environments.

How long does a typical installation take?

Project length depends on the size of the property and the scope of work. Smaller installations may take a short visit, while larger custom systems can require multiple phases.

Is support available after installation?

Yes, we provide ongoing support to keep the system running as expected. That can include troubleshooting, adjustments, and service for future upgrades.
