We Want You to
Feel Secure

Security Solutions for Your Business


CSI (Communication Systems International, LLC) helps you feel safer where you work. Our specialty is commercial security systems that feature video monitoring. For example, we help you keep an eye on employees, visitors, and potential burglars with closed-circuit television.


While our concentration is business security solutions, we provide protection for homes too. We recommend network IP cameras as an effective means of home security. They offer a live feed that you can access via a computer or a smartphone that has a web browser.


Be proactive about property safety by contacting
us for security solutions. (210) 349-8320

Learn About CSI

The security solutions you want are available today. CSI was originally established in 1996 as a telecommunications company. In 2004, CSI realized it had to integrate into a market in which the customer demands one-stop shopping and service to meet the rapid pace of the new business environment. CSI is now a fully integrated and diversified communications and security company serving customers across Texas.

We design and install security systems, fire alarm systems, closed-circuit TV, access control, telephone systems, and data cabling for our customers. All systems are custom designed to customer specifications, and we can integrate our products into a single platform. Our commitment to you begins with our sales representatives performing an in-depth risk analysis of your business. We then present you with a solution that meets your needs and gives you peace of mind about the security of your building.
