Introduction: We provide professional level installs for most of your home security, Audio/Video, and Low voltage needs. We don't pin our customers to long term contracts since we know you'll be happy with our service and installation craftsmanship! I love to be able to provide the best solution for the customers needs by knowing a vast majority of the capabilities that much of the products provide for certain applications. For example, if customers need a security system and have pets, there are different options for that specific application that I can give customers. Also, another example would be giving customers options of Home Audio Video solutions to pick from based on how they want audio and video distributed correctly.

Wiring Installation

Very happy with quality and value of the work by the two techs, Lucas & Cody. I'm already looking to have Poseidon perform some additional work after seeing first hand how good they are. Would have never found Alex and his co. Poseidon Systems without the Thumbtack app.

Home Theater Surround Sound System Installation

Alex was super knowledgeable and responsive. He put in the overtime on a Friday night to get us setup as we moved into our new home and we planning a Super Bowl party at the same time. Great service!

TV Mounting

Poseidon systems did a great job with the installation of our 60" TV and sonos playbar. They also came in as one of the lowest quotes, offering an excellent value.

Home Theater System Wiring

Alex was great and was ready to tackle a complicated HMDI cable repair job for me. When he arrived he pointed out that I had Cat5 cables wired near each end of the HMDI cable an he could convert them using an HDMI Balun to do the same thing and it would be a lot easier and more cost effective. It ended up being less than half of the price of the HDMI cable repair! I really appreciated his honesty and would recommend him for that.
