Central District Alarm

We offer any level of protection, 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. CDA will work with you to customize a system to your exact needs, with service provided within 24 hours.

We are the largest privately owned security company in St. Louis with local monitoring. Family owned and operated by three generations in our nearly 50 years of business. Our professional & experienced representatives will help to custom design your security system depending on your needs—not ours.
