Had issues with 8 new PoE security cameras on my new home (under construction). Not only did Protech (Todd) respond the same day, he adjusted his schedule for my out of town travel… and he showed up early to our appointment and was able to diagnose and fix all eight cameras. Plus, he’s a nice guy. Thanks Todd/Protech… Hope I don’t need you, but happy to call if I do.Posted on Google![]()

Protech has provided outstanding security solutions for both my business and home. Their team designed and installed a state of the art security system with cameras that are reliable and easy to use. The technicians were punctual and took the time to explain the equipment and apps to me. The ongoing service and support have been equally impressive, with quick response times and a commitment to keeping my property secure. Based on this experience Protech is highly recommended for anyone who needs a security system .Posted on Google![]()

I had existing equipment worked on. Todd figured out my issue with just a couple of pictures texted to him. He got the part and came out on a Saturday to get my system back up and running. Friendly and fare pricing.Posted on Google![]()

I had Todd Cavanaugh (sp) at Protech completely redo our security system and wow, what a huge improvement with up to date equipment and a solid week of installing in 100+ temperatures. Fantastic work ethic, too. I couldn’t be happier. Thank you, Todd. Copper Crest subdivision is secure.Posted on Google![]()

From start to finish, Todd and his team were absolutely fantastic. Their honesty and professionalism stood out right away. The customer service was great, and we appreciated the constant communication throughout the entire process. Anytime we had a question or needed an update, Todd and his team were quick to respond and always helpful.Posted on Google![]()

Frequently Asked Questions
Can your home security systems in Sierra Vista detect carbon monoxide buildup too?
Yes we connect CO detectors directly into the main alarm system. They notify your phone and our monitoring team immediately if levels become dangerous.
Who replaces batteries in the door sensors, window sensors, and cameras over time?
We handle battery replacements during regular maintenance visits. Most sensor batteries last 3-5 years before needing replacement. Our technicians check battery levels during service calls and replace them as needed, so you don’t have to worry about it.
What happens to my system and alerts in Sierra Vista if my home internet goes down?
Your system stays protected with cellular backup. If your internet connection drops, the system automatically switches to cellular communication to send alerts to your phone and our monitoring center. You’ll continue receiving notifications without interruption.
How long does a typical installation take in Sierra Vista, and what happens during the process?
Most installations take 4-6 hours depending on the size of your home and the number of devices. Our technicians walk through your home to place sensors and cameras in the best locations, install the control panel, test every device, and show you how to use the system and mobile app before we leave.
How do the motion detectors tell the difference between my pets and an actual intruder?
Our pet-friendly motion detectors use advanced sensors that ignore movement from animals under 40-80 pounds (depending on the model). The sensors detect body heat and movement patterns, so your pets can move freely while the system still detects people. We adjust the sensitivity during installation based on your pet’s size.
