Residential Security Systems in Tucson

25+ YEARS OF TRUSTED LOCAL HOME PROTECTION

Fast Installations and 24/7 Monitoring by Experienced Tucson Technicians Familiar With Your community

Protech Security Systems started in Tucson in 1999. For over 25 years, we have installed home security systems for local families, including alarms, cameras, door/window sensors, motion detectors, and smart home controls. When you call us, you’ll speak directly with Tucson locals who live and work right here. We understand the area’s unique home construction from hillside homes to central neighborhoods and know exactly what kind of protection works best for each setting.

During installation, our technicians take time to walk you through every step until you’re fully comfortable with your system. We carefully inspect doors, windows, and key areas to place sensors for maximum effectiveness. The motion detectors can tell the difference between pets and people, and the smart temperature controls help lower energy bills when you’re away.

Once your system is set up, an easy-to-use mobile app lets you stay connected and in control. You can arm or disarm your system from anywhere, view live camera feeds, and receive instant alerts so you can respond quickly no matter where you are.

Take the next step toward protecting what matters most.

 Trustindex verifies that the original source of the review is Google. 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.

 Trustindex verifies that the original source of the review is 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.

 Trustindex verifies that the original source of the review is 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.

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.

 Trustindex verifies that the original source of the review is Google. We recently had the pleasure of working with Protech Security Systems, owned by Todd Cavanaugh, for the installation of a full security camera system at our plaza in Tucson. 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.

Frequently Asked Questions

Can your residential security systems in Tucson detect carbon monoxide buildup in the home too?

Yes, we integrate CO detectors right into the main alarm system. They’ll notify your phone and our monitoring team immediately if levels get dangerous.

Who takes care of replacing batteries in the door sensors, window sensors, and cameras over time?

We handle all battery changes during regular service visits. Sensors last several years and we swap them out before they cause any problems.

What happens to the system and alerts in Tucson if my home internet goes down unexpectedly?

Our systems use cellular backup so alerts still go out even when WiFi drops. You stay connected through phone cell towers instead of just home internet.

How long does a typical installation take in Tucson, and what happens during the process at my home?

Most residential security system installations take 4-6 hours depending on the size of the home and the number of devices. We’ll give you a time estimate when we provide your quote.

How do the motion detectors know the difference between my pets moving around and an actual intruder?

The motion detectors can tell the difference between pets and people based on heat signature and movement patterns, so your animals can move freely without triggering false alarms.
