Our Testimonials

From families to businesses, read how Preventia has secured our community.

As a school system, we can’t have a system downs due to a failed device for any amount of time. If so, we have to make other costly measures to provide the safety the state requires for our students. Therefore, we continue to see incredible response times on service calls. We continue to use them on our new buildings.

Our school district first hired Preventia 8 years ago. They were able to replace a failed system in one of our schools in a small window of time successfully. They monitor all of our 23 schools and provide excellent service!

From my installation coordinator who did a great job of setting everything up in a friendly and professional manner all the way to my tech who installed my new security system and smoke alarms. Preventia Security was very professional and friendly. They explained everything to me and made sure I understood. They did a great job and I am a happy customer.

Preventia was super helpful in teaching me how to operate everything. The tech tested the alarms and got everything working A+.

The scope of work they perform on our construction developments across the southeast and central US includes security cameras, speakers, audio/ visual, access controls, fire alarm and site construction cameras/ alert systems. I appreciate how involved they are from ownership level all the way to install.
