"We wanted to get on board with the current trend in doorbell cameras. Got a quote from ADT Provider, known as Safe Street USA, and felt their offer was more than fair. We have door sensors and motion detectors inside and the doorbell camera mounted outside. Nice to feel “with the times” in home automation and security."

"Protect Your Home group with ADT has exceeding our expectations in getting a new home security system. In the end, everything was a breeze and not stressful whatsoever. We tested the siren and our neighbors 2 doors down could hear it; which is what we were hoping for!"

"Excellent job! Mr Temur K was incredible fast, professional, and made sure my window AC unit was secure and cooling properly perfectly. Highly recommend his installation services! 👍"

I am the founder and lead technical strategist of Hyperion Fire & Security LLC, based right here in New York City. My professional journey is rooted in a deep commitment to life safety, backed by a NICET certification in Fire Alarm Systems.\nI didn't start this company to be just another high-volume "inspect and move on" vendor. I started it to be a technical shield for property owners who are tired of recurring system faults and confusing code requirements.\nMy Professional Foundation\nMy expertise is built on the front lines of the New York fire safety industry:\n * Technical Specialist: I specialize in the "brains" of modern life safety—specifically proprietary systems like the Edwards EST3, EST4, and iO-series. While others might see a communication fault as a reason to replace a whole panel, I see it as a puzzle to be solved through precise diagnostics.\n * Code-First Mentality: I believe that compliance isn't a burden; it’s a blueprint for

"They were pleasant and professional. They arrived quickly, assessed the situation & fixed the problem. I wanted a security lock, so had to pay more."

"Great company! I needed to replace my regular door and security door. Valentino (the owner) had come by for a free assessment and estimate. He provided a fair assessment without being pushy which I greatly appreciated. The doors were custom made according to the specifications I had chosen. The crew that came by to do the installation were friendly, professional and were respectful of my property. As part of the installation of the doors, they also had to do new jambs and the bottom (I previously had a half step). The end result is absolutely beautiful and I am so happy with my new doors. They are well sealed when closed and I no longer have a draft. I highly recommend Custom Windows & Doors!!"
