At CDA, we offer any level of protection you may want, from door alarms and motion detectors to complex, state-of-the-art closed circuit televisions. We make it easy for you to select the right security program, too. A CDA security consultant will show you the three levels of security - Basic, Standard, And Enhanced - and discuss the benefits of each. Once you decide which level makes you most comfortable, CDA will work with you to customize a system to your exact needs. 1. Service provided 24/7. 2. U.L. listed Central Station for Commercial and Residential systems located in St. Louis. 3. Largest privately owned Security Company in St. Louis with Local Monitoring. 4. Family owned and operated by three generations in their 60th year of business. 5. Professional & Experienced representatives help to custom design your security system depending on your needs, not ours. CDA is fully approved by the Underwriters Laboratory. That means we are constantly monitored by audited service tests, unannounced and in cooperation with local police departments, to assure compliance with strict UL regulations, both technically and in quality of personnel response. There is no greater certification available to security companies. And no greater assurance that your CDA security program will work for you and your family at peak performance all the time.
