Controlled Access Inc.

Controlled Access Inc. (CAI) has been Atlanta's premier provider of comprehensive security systems for over 30 years — a Marietta-based integrator specializing in access control, video surveillance, gate systems, audio-visual, parking and revenue management, and low voltage solutions for commercial, residential, and multi-family clients across Metro Atlanta and key Georgia markets.
