I have had the pleasure of working with Clark Surveillance Tech Group for over five years now, and cannot rave enough about their professionalism and quality installation.
I work for an installer referral company that contracts work to Clark Surveillance Tech Group. Time and time again, I choose Clark Surveillance Tech Group over other installation companies, because I know when I have a project to be completed, that Clark Surveillance Tech Group will immediately accept it, schedule promptly with the customer, arrive on time (if not early), keep the customer aware and educated throughout the installation, and provide a quality installation (for an extremely reasonable price). My company requires documentation upon completion of the installations Clark Surveillance Tech Group performs, so I am able to (first-hand) see the quality in their workmanship and am thoroughly impressed each time. Their company has maintained an A+ rating (which comes directly from customers' surveys).
If you are seeking an outstanding installation, with a very reasonable price, you NEED Clark Surveillance Tech Group.
