Brilliant Connectivity - Ubiquiti server, a wifi broadcast, and some cameras

Brilliant Connectivity

(7 reviews)

We realized one of the most important decisions for our new home was choosing a whole home…read morenetworking system with lots of capacity and capability. As a consultant, I work from home and my wife works from home most days, so we needed a great system that accommodates lots of video calls, as well as home security, entertainment, a growing list of indoor and outdoor app-controlled devices, and strong wifi access for friends, colleagues, and family who stop by. And we also know that, in the future, nearly everything will need to be connected to the network. After weeks of searching for a solution, we discovered Brilliant Connectivity, which designs and installs Ubiquiti Unifi networking systems, the finest high-performance networks and wireless products on the market. Daniel G, the owner and founder, is a senior IT expert with deep knowledge and experience using Ubiquiti products to create customized networking solutions for his clients. And his installer, Rafael, did an excellent and clean installation that covers our entire house, upstairs, downstairs, interior and exterior. It is our pleasure to give Brilliant Connectivity our highest recommendation. Thanks to them, we have a home networking solution that meets all of our needs, and there are no more frustrating IT glitches and time-consuming DIY fixes to deal with. Thank you, Daniel and Rafael!

I brought in Brilliant Connectivity to do a WiFi upgrade for my employer, who was having a lot of…read moreconnectivity issues trying to work from his office in his large Alamo home. Daniel & Raphael are a great team and they do very clean work - friendly, professional, and super fast. They got the whole place wired up and humming within a day. Additionally, I hired them to take care of a home w/ a guest house in Napa, and the guys dialed in that property too. Getting them great coverage through the main ranch house and then running a trench to wire up the guest house in the back of the property. 5 stars!

If we could give them a negative 100 we would. This company…read morewas hired to do a Control4 upgrade of my system and was given a list of tasks to perform. Their quote was higher than other dealers but the assurances they gave to fix everything got us to select them. They came in and replaced a lot of hardware saying it was needed to make the system better. Granko did the hardware work and one task out of 12 and then refused to finish the job but wanted to be paid a $5,000 balance on a $13,000 quote. Then they insisted on getting another $15,000 to finish the work they promised would be done in the first job and even more money for other work. We refused to pay the bill until the work was completed as agreed and the owner's wife threatened collections and court. Then when we refused to pay because they would not make it right, our entire system crashed and was not operatable for 5 days. Turns out they installed software to allow them to get into the system remotely which they did not have permission to install and they concealed it from me and did not provide the passwords to the system. We know that Granko turned off our system remotely because they said " Gee we can fix your system easily, just pay the bill for the work you say we didn't do!" We had to pay a network company to come in and reset the wifi system and remove the secret access that Granko installed. DON'T USE THIS COMPANY THEY ARE MISREPRESENTING CAPABILITY, AND DON'T KEEP THEIR WORD. THEY REFUSED TO COMPROMISE AND THEY OVERESTIMATED THEIR WORTH. THEY GIVE US A BIG STORY AND DIDN'T LIVE UP TO 10% OF WHAT THEY PROMISED. WE ARE SUING THIS COMPANY TO RECOVER OUR LOSSES AND HAVE OUR SYSTEM RESTORED BY ANOTHER COMPANY AT GRANKO'S EXPENSE. This company is a ripoff and can't be trusted. They tell you one thing and do something else. Our system is slower and crashes now than when they started working on the system. The problems increased instead of being solved.

We could not recommend Granko more enthusiastically... Ryan Granko consulted with us about…read moreupgrading our internet set-up and provided us w a proposal. It is a system supporting a main house and 2 out buildings, one being 150 ft away. Suffice it say, they did an awesome job! They persevered through issues and wouldn't stop until they solved everything, including a very temperamental Sonos app. Additionally, our Xfinity monthly costs are cheaper as we don't need their modem. The entire team is professional, smart, communicative, responsive and friendly! Was a great experience... thanks Granko

Kurtis's team set our house up with a wired and wireless network and security cameras. He also…read moremounted our TV on the wall and hid all cables to make it fit well in our living room. Aside from being very knowledgeable about his domain, Kurtis and his team are also able to think creatively about different solutions. The pathway they created for all the wiring took them a great deal of effort, but it's almost invisible, both inside and outside the house. Their team worked tirelessly to make sure everything was installed well while maintaining the esthetic of our house. Asking for small adjustments, like lowering the TV after the first installment or removing older cameras, was never an issue. It was an absolute pleasure to work with Kurtis, and I'd be more than happy to approach him again for future projects.

I just ran into him and seeing him reminded me that I meant to write a review after I decided whether their work was worth the money. Ours was probably a small-to-mid-size job for him, but it felt big to us, and Kurtis and team were sensitive to our concerns, as well as very efficient at getting the job done. We have been extremely happy with our new TVs with upgraded sound, our extended wifi, and mind-blowing theater system in our "man cave". I 100% recommend Kurtis Company.
