A distribution center manager near Memphis International Airport asked me a question last month that I’ve been hearing more frequently from commercial property operators across Shelby County: “Should I be looking at drones instead of adding another guard?”
It’s a reasonable question. The numbers look compelling on paper. A security drone can cover a 40-acre property perimeter in 12 minutes, flying a preprogrammed route with thermal imaging cameras that detect human-sized heat signatures day or night. A guard walking the same perimeter takes over an hour and can’t see through darkness, around corners, or over fences. The drone doesn’t call in sick, doesn’t need breaks, and doesn’t collect workers’ comp.
The reality is more complicated than the sales pitch. And in Tennessee, the regulatory framework adds layers that property managers need to understand before writing a purchase order.
Where Drone Security Stands Right Now
The commercial security drone market has grown substantially since 2022. Companies like Nightingale Security, Sunflower Labs, and Asylon offer autonomous drone-in-a-box systems designed specifically for perimeter security. The concept is straightforward: a drone sits in a weatherproof charging station on your property. At programmed intervals, or when triggered by a sensor alert, it launches, flies a patrol route, captures video, and returns to recharge.
Several large distribution and logistics facilities in the Southeast have deployed these systems over the past two years. A FedEx sorting facility in Texas has been testing autonomous drone patrols since late 2023. Amazon has publicly discussed drone security for its warehouse network. In Tennessee, the adoption is earlier stage. A handful of industrial properties in the Nashville area have pilot programs running. I haven’t confirmed any fully operational autonomous drone security systems in the Memphis market as of this writing, though at least two security companies told me they’re evaluating the technology for client proposals.
The hardware has reached a point where reliability isn’t the primary barrier. Modern commercial security drones can fly in wind up to 25-30 mph, navigate in rain (with limitations), and operate through a full 24-hour cycle with rotating charge-and-fly schedules. Battery life has improved to 35-45 minutes of flight time per charge, and docking stations can turn a drone around in 20-30 minutes.
The barriers are regulatory, operational, and economic. In that order.
Tennessee’s Regulatory Framework
Federal Aviation Administration rules govern drone operations nationwide. For commercial security applications, the key regulation is Part 107, which requires a Remote Pilot Certificate for anyone operating a drone for commercial purposes. That includes security patrols.
Part 107 carries restrictions that directly affect security use cases. Flights must remain within visual line of sight of the operator (VLOS), which limits the effective patrol radius to roughly 1-2 miles depending on terrain and obstructions. Flights above 400 feet AGL are prohibited. Night operations are permitted under Part 107 with proper anti-collision lighting, which removes what used to be a major obstacle for security applications.
The VLOS requirement is the biggest practical challenge. A truly autonomous drone patrol (launched, flown, and recovered without a human pilot maintaining visual contact) requires a Part 107 waiver for Beyond Visual Line of Sight (BVLOS) operations. The FAA has been granting these waivers selectively, and the process is neither fast nor guaranteed. As of early 2025, the number of active BVLOS waivers in Tennessee is small. Most approved operations are for infrastructure inspection and agricultural applications, not security.
Without a BVLOS waiver, you need a licensed pilot on site whenever the drone is airborne. That changes the economics significantly. Instead of replacing a guard with a drone, you’re adding a drone operator alongside your existing security team. The technology becomes a supplement rather than a substitute.
Tennessee state law adds a separate layer. T.C.A. Section 39-13-903 restricts the use of drones for surveillance purposes. Law enforcement agencies have specific statutory authority for drone surveillance under certain conditions. Private entities operating drones for security purposes need to navigate privacy considerations carefully, particularly when drone flight paths cross neighboring properties or public spaces. Recording video of individuals without consent from a drone can create liability under Tennessee’s privacy statutes.
The Cost Equation
Here’s where most property managers’ interest either solidifies or evaporates.
A fully autonomous drone-in-a-box system from a major vendor costs between $70,000 and $150,000 for hardware, installation, and the first year of software licensing. Annual software and maintenance fees after year one run $15,000-30,000. If you need a BVLOS waiver, add $10,000-25,000 in consulting and legal fees with no guarantee of approval.
Compare that to a security guard. At $18-22 per hour (the current Memphis market range for unarmed commercial security), a single guard post running 24/7 costs roughly $160,000-195,000 annually when you factor in the security company’s markup, overtime, and holiday premiums. A second guard at the same property adds another $160,000-plus.
On a pure cost comparison, a $120,000 drone system that replaces one guard position pays for itself in about 18 months and saves money every year after that. The catch: it doesn’t actually replace the guard. Not yet. VLOS requirements mean you still need a human on site. And a drone can’t check credentials, interact with visitors, detain a trespasser, or respond to a medical emergency.
The more realistic economic model is one where a drone extends the effective range of a smaller guard force. Instead of three guards covering a large industrial property with walking patrols, you deploy two guards at fixed positions and a drone covering the perimeter. You reduce headcount by one position and improve coverage. That math works on properties of 20 acres or more, where the drone’s speed advantage over walking patrols is most pronounced.
Where Drones Make Sense in Memphis
Not every property benefits from drone security. The technology fits best in specific scenarios.
Large industrial and logistics facilities. The distribution centers, warehouses, and manufacturing plants clustered along the I-40 and I-55 corridors south and east of Memphis International Airport are prime candidates. These properties have large perimeters, limited access points, and high-value inventory. A drone circling the fence line every 15 minutes provides detection capability that would require three or four guards to match on foot.
Solar farms and utility infrastructure. Tennessee’s growing solar installation base includes several large-scale facilities in the Memphis metro area. These sites are often remote, unmanned, and spread across hundreds of acres. Copper theft and equipment vandalism are persistent problems. A drone can survey a 200-acre solar farm in under 20 minutes.
Construction sites. Equipment theft from active construction sites in Memphis costs contractors millions annually. The stretch of development along the I-269 corridor and in the Collierville growth area creates seasonal security demand. Drones equipped with thermal cameras can detect after-hours intruders across sprawling construction zones more effectively than a single roving guard.
Properties where drones DON’T make sense include urban commercial buildings (too many airspace conflicts and privacy concerns), residential communities (noise complaints and legal exposure), and any facility in controlled airspace near Memphis International Airport without specific FAA coordination. The airport proximity issue affects a significant portion of the Memphis industrial market, since many of the warehouse and distribution properties that would benefit most from drone security sit within the airport’s Class C airspace, requiring additional FAA coordination for any commercial drone operations.
What to Do If You’re Interested
If drone security makes strategic sense for your property, start with three steps.
One: consult an aviation attorney familiar with Part 107 and Tennessee drone law before purchasing equipment. The regulatory compliance costs should be factored into your total cost of ownership, and you need to understand what’s permissible on your specific property.
Two: talk to your insurance carrier. Commercial drone operations create liability exposure that your standard property insurance may not cover. Some insurers offer drone-specific endorsements. Others will want a risk assessment before extending coverage.
Three: contact your current security provider. Some of the national firms operating in Memphis (Allied Universal, Securitas) have drone integration programs at the corporate level and can deploy systems through their existing contracts. Mid-size Memphis operators are earlier in the adoption curve, and a few are actively partnering with drone technology vendors to bring capabilities to their client base.
The technology is real, it works, and for the right applications it’s cost-effective. It’s also not magic, and it’s not a guard replacement. Treat it like any other security tool: evaluate it against your specific risk profile, run the numbers for your specific property, and make sure the regulatory boxes are checked before the first flight. Memphis properties will be using security drones routinely within a few years. The question for 2025 is whether your property’s risk profile and economics justify being an early adopter.
