We had a great experience with TCI! Mario was extremely helpful in coordinating the installation and made the entire process smooth and easy. Bobby handled the installation and provided excellent customer service — very professional, friendly, and efficient. Everything was completed on time and works perfectly. Highly recommend their team!

I had them install a 4 camera NVR system that I bought myself. The install was quick and professionally done, and they also set up and explained the system to me. I am very happy with their work.

TCI installed security cameras at our office and home. Their customer service was excellent. They showed up on time and cleaned up after completing the job. I would recommend Gabriel and his Team for any Job.

Gabriel installed new NVR and upgraded two of our cameras. He made himself available and quickly installed the equipment. Always a pleasure working with Gabriel.

I had TCI install 7 cameras and a video doorbell. Ivan and his team did an excellent job. The cameras look good, they showed me how to work them, they answered all my questions, they kept the worksite clean.

Had our camera system installed by Gabriel and his team about 7(?) years ago. It?s worked flawlessly since that time except for a few minor issues related to neighborhood power outages over the years. Those issues (primarily due to my own lack of knowledge) were immediately resolved by a simple text message from Gabriel on how to reboot the system. Recently our system went down due to a power cord issue. TCI came out to diagnose and replace the power cord but didn?t even charge for the service call or cord despite being out of warranty for many years. Top notch professionals!

Gabriel from TCI services was incredibly helpful. Cameras were up and working within 1 hour and he was able to walk me through monitoring my home on my mobile phone. 5 Star service.
