Drone ROI in Baltimore, MD: Patrol Hours and Payback

What is drone ROI in Baltimore?

Drone ROI in Baltimore is the return a business gets when drones take over repeat security patrol work that a guard would otherwise do. It is measured as labor hours offset, set against the cost of the lease and the flight staff the drone needs. For most sites it is a partial offset, because a drone covers patrol and observation while a person still handles response and intervention.

This page explains where the return comes from, how the savings range is calculated, what moves it, and how to get a precise number. The calculator on this page is set for Baltimore, MD and shows a savings range built from the government wage data for the local guard job. Ranges are not promises. The figure firms up only after someone maps the site and counts the patrol hours.

Why do Baltimore guard hours matter for drones?

Security guard work is the labor side of this math. The government wage data on this page gives the local wage for the security guard job in Baltimore, MD, and that wage is the value of each hour a drone takes over. The BLS Occupational Outlook Handbook projects 5,100 jobs added in security guard work from 2024 to 2034, with little or no change in overall employment, so the job is steady rather than growing fast.

The bigger cost driver is turnover. According to the UC Berkeley Labor Center, as reported in trade press, annual turnover in the US security industry was 89 percent in 2024, against 66 percent for the private sector overall. The Labor Center says the industry has exceeded the private-sector average every year for a decade. Each departure brings hiring, screening and training hours that the site pays for again.

An aggregator citing BLS OEWS May 2024 lists about 15,310 security guards in the Baltimore metro. We have not checked that figure against the BLS table, so treat it as a rough local count and confirm it for your own planning.

Where does the drone return actually come from?

The return comes from three places. The first is patrol hours that a drone flies instead of a guard walking or driving the same route. The second is fewer hours spent on scheduled rounds that a drone can repeat on time. The third is lower staff exposure to repetitive checks. The first is usually the largest. A drone flies a fixed route, checks the same gates and fences, and reports what it sees, so each route that moves to the air frees a guard for other work.

The return does not come from removing the guard entirely. Industry commentary the research reviewed says robots typically replace patrol coverage while a person still handles response and intervention. Savings therefore tend to come from pairing drones with a smaller guard force rather than replacing one, and that pairing is where most of the value sits in Baltimore.

Injury exposure is a smaller lever. The Bureau of Labor Statistics fact sheet reported nonfatal injuries and illnesses requiring days away from work at 107.8 per 10,000 full-time security guards in 2007, which was 11.8 percent below all private industry. That data is dated and no current guard-specific rate was found, so treat it as context, not a forecast.

How does the savings math work?

The calculation starts with labor hours offset, which is the hours per week of patrol work the drone takes over. Multiply those hours by the local wage for the security guard job from the government wage data on this page, then multiply by the share of that work the drone realistically covers. A drone rarely covers a whole route, since weather, obstacles and sensor limits leave gaps that a guard must fill.

From that gross figure, subtract the lease cost, the flight staffing needed to operate and monitor the drone, and any added software or service you choose. What remains is the net offset, which the calculator shows as a range. The low end assumes a smaller share of coverage and heavier staffing. The high end assumes the drone covers most of a repeat route with little extra staff.

The lease cost is not fixed on this page. A fixed robot lease payment is quoted after a free site assessment, based on the drone, the mission and the service level. Compare quotes with service terms included, because a lease with service included and one without are not the same cost.

What changes the number up or down?

The number moves most with the patrol hours you can actually offset and with how much of each route a drone can cover. Routes with clear sightlines and repeat paths raise the share. Routes with frequent obstacles, poor conditions or heavy need for in-person contact lower it. Flight staffing is the input most often underestimated, and it can erase a large part of the offset if one person covers too many tasks.

The local wage for the guard job sets the value of each hour, so the government wage data in Baltimore matters more than any national average. Turnover adds value where hiring and training recur often, because those hours are a cost the drone can reduce. The checklist below lists what to verify before you rely on the range.

What hours does a drone take over?

The table below shows the work a drone typically takes over, task by task. It describes the work rather than timing it. The research did not find a published drone flight-hours figure per shift or per site for guard-type patrol, so measured hours for your site come from the site assessment, where we walk the routes and time them.

The main shift is repeat patrol. A guard on a fixed round walks or drives the same perimeter and checks the same doors, gates and lots. A drone flies the same route on schedule and sends images back to a monitor, so the person who would have walked it can handle alarms or respond to what the drone reports. Conditions decide which routes move to air, so the assessment confirms lighting, sensors and weather limits for each route.

What are the risks to the return and how do you avoid them?

The biggest risk to drone ROI in Baltimore is a route the drone cannot fly well. The guard still covers that ground, and the drone's cost is added on top. Avoid this by mapping the site first and counting only routes a drone can fly on a repeat schedule. Partial coverage still returns value, but it has to be counted honestly.

The second risk is poor staffing. If one pilot or monitor is pulled away for other work, the offset disappears. Set a written staffing plan for flights and monitoring before go-live, and protect the number by checking it during the pilot.

The third risk is response. The drone reports, but a person must respond to alarms. Keep enough guard coverage for response, and treat any plan that removes all response coverage as a risk to both the return and safety.

The data is also uneven. Bureau of Labor Statistics Monthly Labor Review summary of 2009 data counted 63 fatal work injuries and an estimated 8,920 nonfatal injuries or illnesses with at least one day away from work for guards. A drone vendor executive quoted in trade press says drone patrols run 30 to 50 percent cheaper than comparable guard contracts, which is vendor-reported. Use both as context, not as your figure.

Drone or guard: how do they compare?

Drones and guards do different things well, and an honest comparison shows where each wins. A drone is consistent on a fixed route, does not tire on a long round, and can see a large area quickly from the air. A person can judge a situation, speak to people, refer a matter and act on something unexpected.

A drone-supported patrol is cheaper per route only when the route suits flight. The trade press report of the 30 to 50 percent figure is vendor-reported and not independently verified, so the offset should come from your own pilot.

A 2025 vendor-sponsored survey reported in trade press found nearly half of first responders expect daily drone and robotics use within a few years. That shows where the public safety field is heading, not what a Baltimore site will save.

What is a realistic timeline from assessment to payback?

The timeline runs in stages: assessment and mapping first, then a pilot on one route or site, then a wider rollout once the offset is measured. We do not promise a payback date before the site is mapped. Each stage depends on the site, the routes and any permissions the drone needs to fly over the property.

A single-route pilot is the cleanest way to measure the offset. Run it long enough to see the real patrol pattern, count the hours the drone took over, and compare that with the calculator range. If the pilot holds, the wider rollout uses the measured figure rather than an estimate.

Payback follows from the measured offset minus lease cost and flight staffing. Because the lease cost comes from the quote, payback depends mainly on how many routes move to air and how well staff cover the drone's flights. A short pilot is the fastest way to learn which way your site leans.

How do I get a precise figure from a free site assessment?

A free site assessment is where the range becomes a number. We map the site, time the patrol routes, identify which routes a drone can fly well and confirm staffing for flights and monitoring. The calculator then uses your measured hours and the local guard wage from the government data to produce a range you can review.

After the assessment you receive a fixed robot lease payment quote with service terms included, so you compare a complete cost against the measured offset. We pick the drone that fits the site, lease it through financing, deploy and integrate it, train your staff and service it nationwide.

Bring your current patrol schedule, guard headcount, turnover history and any site maps. Those inputs let the assessment produce a range you can take into a budget review.
