What Our Clients Say
"We've used AD Security for three separate projects over the years, including a gate install, camera system, and card reader upgrade. They remember our setup every time and always deliver clean, reliable work."
"After a break-in attempt, AD Security had a full camera and intercom system installed within the week. They walked us through everything and even helped us file the footage with the police. Above and beyond."
"We manage 14 properties and AD Security handles all of our access control. Their team is responsive, knows the equipment inside out, and their pricing has stayed fair for over five years."
"The turnstile gate they installed in our office lobby completely changed how we manage visitor access. Clean installation, minimal downtime, and the system integrates with our existing badges."
