Business security systems
Intrusion alarms, sensors, monitoring and whole-building security planning.
● Commercial security
Alarms, cameras, door access, live video monitoring and fire protection from one local company. Planned around your building, installed by our own crews and supported from offices in Smyrna and Chattanooga since 1976.

Turner Security designs, installs, monitors and services commercial security systems: intrusion alarms, security cameras, access control, live video monitoring with talk-down, AI video analytics, mobile camera trailers, fire alarm systems and the recorders behind them. Our offices in Smyrna and Chattanooga serve Middle Tennessee, the Chattanooga region and national multi-site customers.
Because our sister company TechCore handles business IT, one team can plan the security system and the network it runs on. There are no long-term contracts on security or monitoring.
Most customers start with one need and grow into a connected system. Every service below can be planned on its own or together.
Intrusion alarms, sensors, monitoring and whole-building security planning.
Cards, fobs and phones on your doors and gates, with schedules and entry history.
Clear video of entrances, lots, docks and inventory, viewable from your phone.
Agents watch your cameras live and talk down trespassers before damage is done.
Smart alerts and license plate recognition added to most existing cameras.
Solar camera trailers for job sites, lots, events and temporary locations.
Fire alarm installation, monitoring, inspection and service.
Recorders and video servers sized for your cameras, retention and remote access.
We have protected businesses in Tennessee since 1976. Customers stay because the service is good, not because a contract makes them. That is why we do not require long-term agreements on security or monitoring.
When something goes wrong, our help desk starts on it right away and resolves most issues remotely before a truck rolls. When a visit is needed, we can often schedule it the same day you call.
Warehouses, manufacturers, dealerships, property managers, churches and schools all have different risks. See how we approach each one, or find your local office.

Great products, great service, great price! We needed to establish a solid security setup for our small business that wouldn't break the bank. After getting quotes from a few providers, we went with Turner as they are locally owned and offer the same top-notch technologies as the bigger companies, only at a more competitive price. 24/7, Turner Security has us covered and we're so thankful!
Richard did a great job setting up the security system at my place of work. He was very professional and thorough.
TPQVO has been with Turner Security for many many years and we have nothing but good things to say about them. The staff is great and very accessible if you need someone. We highly recommend this company.
