Entrance & Gate Intercom Systems

Entrance & Gate Intercom Systems for Secure Entry Control

Talk to Visitors Before You Let Them In

Controlling entry to your building starts with knowing who’s outside. Our intercom systems let you see and speak to visitors before they step through the door. With options for audio-only or full video, you can choose the setup that fits your space and security level.

These systems are easy to use and install cleanly at entry points, gates, or front desks. From small offices to large commercial properties, we make it simple to manage who gets in, without stepping away from your work or guessing who’s knocking.

Why Businesses Choose Our Intercom Systems

In schools, offices, gated communities, and healthcare facilities, control at the front door matters. You can verify deliveries, guests, and late‑night visitors without sending someone to answer every time. It’s smarter, faster, and more secure.

You won’t need extra staff to monitor entrances. Instead, one person can easily manage access with just a glance and a click, keeping your site safe and operations smooth.

 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. 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 .

 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.

 Trustindex verifies that the original source of the review is 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.

 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.
