Intrusion alarms
Door contacts, motion detectors, glass break sensors and sirens tied to a commercial alarm panel that you arm and disarm by keypad or phone.
● Commercial security
Intrusion alarms, cameras, door access and monitoring planned as one system around how your building actually runs. Installed, monitored and serviced by a local team in Nashville and Chattanooga since 1976.

A commercial security system is the set of intrusion sensors, alarm panel, cameras, door access and monitoring that protects a business when people are there and when they are not. A good one is planned as a whole, so an alarm, a door event and a camera clip all tell the same story.
Turner Security designs, installs and monitors business security systems for companies across Middle Tennessee and the Chattanooga area from offices in Smyrna and Chattanooga. There are no long-term contracts on security or monitoring, and we can often schedule service the same day you call.
Every project starts with a walkthrough of your property, your people and your hours. These are the pieces we put together.
Door contacts, motion detectors, glass break sensors and sirens tied to a commercial alarm panel that you arm and disarm by keypad or phone.
When an alarm trips, a central station is notified and follows your call list and dispatch instructions, day or night.
Camera coverage of entrances, lots, docks and inventory so every alarm can be checked against video.
Cards, fobs or phones on the doors that matter, with schedules and entry history instead of loose keys.
Give each employee their own code, limit who can disarm which areas, and see who opened or closed the building.
Moved into a building with an existing system? We review what is there, reuse what still works and tell you plainly what should be replaced.
Most break-ins and false alarms trace back to the same problems: sensors in the wrong places, old panels nobody knows how to use, and cameras that do not cover what the alarm is protecting. Planning everything together closes those gaps.
Support matters just as much. Our help desk resolves most service issues remotely before a truck ever rolls, and when a technician is needed we can often get one scheduled the same day.

One local team handles the plan, the install and the service.
We walk your doors, windows, lots and high-value areas and ask how your day and your after-hours actually work.
You get a clear plan for sensors, panel, cameras, access and monitoring, with a clear price before any work starts.
Our crews install and test every zone, set up user codes and confirm signals reach the monitoring center.
We show your team how to arm, disarm and use the app, then stay available for service and changes.
Cost depends on the size of the building, the number of doors and zones, and whether you add cameras, access control or video monitoring. We do a free walkthrough and give you a written proposal with a clear price before any work starts.
No. Turner Security does not require long-term agreements on security or monitoring. We want to keep your business because we did a good job, not because of a three or five year contract.
In many cases, yes. We review the panel, sensors and wiring that are already in place, reuse what still works and tell you what needs to be replaced before we switch monitoring over.
Call or submit a service request and our help desk will start working on it right away. Most issues are resolved remotely, and when a technician is needed we can often schedule the visit the same day.
Yes. We plan them as one system so an alarm event can be checked against camera video and door activity, and so you can manage everything from your phone.

Networks, IP phones, servers and managed IT are handled by our sister company, TechCore. Same owners, same local team, one call for security and IT.
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.
