Evolv Express Review Evolv Weapons Detection Cost, the FTC Order, and Whether It Belongs in Your School
Evolv Express is a walk-through weapons screening system that uses sensors and software instead of a traditional metal detector, so people can pass without emptying their pockets. It is the most widely deployed system of its kind in US schools and stadiums, and also the one the Federal Trade Commission took action against in 2024 over how it was marketed. This review works only from the public record and Evolv's own materials, covers what the FTC actually found, and says plainly where camera-based detection fits instead. We sell camera-based software, so every claim below is attributed.
What Is Evolv Express?
Evolv Express is a free-standing screening pedestal that people walk between as they enter a building. It uses sensor technology and machine learning to flag concealed weapons, and it is designed to let visitors keep phones, keys, and laptops in their bags rather than emptying pockets the way a walk-through metal detector requires. Evolv reports its systems are in more than 800 schools across 40 states, plus stadiums, hospitals, and venues. It is sold mainly as a multi-year subscription rather than an outright purchase.
The reason Evolv shows up in every school safety conversation is not only its footprint. In 2024 the FTC filed a complaint over the company's marketing, and Evolv settled. The settlement bars unsupported claims and, notably, gave a defined group of K-12 school customers the right to cancel their contracts. That is the single most important thing a district evaluating Evolv today needs to understand, so this review leads with it rather than burying it. Evolv did not admit wrongdoing, and the settlement carried no monetary penalty. Worth knowing before you compare quotes: the same sensor platform is resold under another brand as Motorola Solutions concealed weapons detection, so putting the two side by side is not the independent second opinion it appears to be.

How Evolv Express Works
Evolv is a screening portal, not a camera product. It answers one question at one place: is this person carrying a weapon as they walk through this lane.
Sensors, not X-ray
Express uses low-frequency electromagnetic sensing rather than the X-ray or single-coil metal detection of an airport lane. The stated goal is throughput: people walk through at a normal pace without stopping to empty pockets, which is where the marketing promise and the FTC complaint both centered.
Software classifies the signature
Machine learning tries to tell the shape and signature of a firearm or large knife from benign metal like a laptop or water bottle. When it flags a threat, a tablet shows a screener roughly where on the body to check, so the follow-up search is targeted rather than a full pat-down.
A human resolves every alarm
Every alert still needs a person to divert the visitor and confirm or clear it. This is the labor Evolv marketed as reduced versus metal detectors, and it is also where real deployments add staff. The lane does nothing on its own once someone alarms.
It covers the doorway, nothing else
Express secures the lane it stands in. It has no view of the parking lot, the athletic field, a side door propped open, or a hallway after entry. Anything past the pedestal is outside its scope, which is the structural gap camera analytics exist to fill.
The FTC Order Is About Marketing, and It Gave Some Schools an Exit
In late 2024 the Federal Trade Commission filed a complaint alleging Evolv made claims it could not support. Per the FTC, Evolv represented that Express would detect all weapons, ignore harmless personal items without requiring people to remove them from pockets or bags, detect weapons more accurately and faster than metal detectors, reduce false alarms, and cut labor costs by around 70 percent compared with metal detectors. The agency alleged these claims were not adequately substantiated.
Evolv settled. It did not admit wrongdoing and paid no monetary penalty. The order bars Evolv from making unsupported claims about its products detecting weapons using artificial intelligence. The part that matters most for a school buyer: the settlement gave certain K-12 customers the option to cancel their Evolv contracts, specifically contracts signed between April 1, 2022 and June 30, 2023. If your district signed in that window, you may have a cancellation right worth reviewing with counsel.
Read the order for what it is. It does not say Evolv Express does not work, and it does not ban the product. It says the earlier marketing outran the evidence. The underlying scrutiny was fueled by incidents where scanners were in place and did not catch the weapon used, including school stabbings in Ohio and New York where the blades were not detected. That is the useful lesson for any screening buyer: a lane tuned for throughput and for firearm-shaped metal is not the same as a lane that catches every knife, and no screening system removes the need for the human who resolves the alarm.
- That Evolv, or any system, detects all weapons. The FTC specifically challenged that claim.
- A single accuracy percentage for Evolv, which the company does not publish and the order discourages.
- That camera AI, ours included, finds a concealed weapon. It does not.
- That either approach removes the trained human who has to resolve an alert.
Evolv Express Cost: What a Signed RFP Actually Shows
Evolv does not publish a price list, and the figure that circulates online, around $2,500 a month or roughly $120,000 over a four-year subscription per unit, is only the middle of the range. A public school district RFP puts real numbers on both ends. These are the pedestal subscription totals over 48 months, before the staffing you add to resolve alarms.
| Configuration | 48-month subscription | Effective per month |
|---|---|---|
| Single lane, indoor | $78,810 | ~$1,642 |
| Typical single-unit figure quoted online | ~$120,000 | ~$2,500 |
| Dual lane, outdoor rated | $153,290 | ~$3,194 |
The spread is the point. An indoor single lane and an outdoor dual lane differ by nearly double, so a district that budgets off the commonly quoted middle figure will misjudge a multi-entrance rollout badly. Add the recurring staffing to divert and resolve alarms at each active lane, and the true cost of covering several entrances climbs quickly.

Evolv Express vs Camera-Based Detection: the Honest Comparison
These are not the same product and they are not really rivals. Evolv secures a doorway. Camera AI watches everything past it. The table concedes every row where screening wins, because for concealed weapons at a controlled entrance, it does.
| Dimension | Evolv Express (entrance screening) | Surveillant (camera AI) |
|---|---|---|
| Concealed weapons | Yes, at the lane. This is the entire point. | No. A concealed gun has no visual signature. |
| Coverage area | The doorway the pedestal stands in. | Every camera on the property, indoors and out. |
| Parking lots and fields | Not covered. | Covered wherever a camera looks. |
| Drawn weapon in a hallway | No. Screening already happened at the door. | Yes, that is the primary use case. |
| New hardware | A pedestal per lane, subscription or lease. | None. Runs on existing ONVIF and RTSP cameras. |
| Added staffing | A screener at every active lane to resolve alarms. | None added. Alerts route to existing staff or phones. |
| Published pricing | No. Signed RFPs show $78,810 to $153,290 over 48 months per config. | Yes. $39 to $42 per camera per month. |
| After-hours coverage | Only when the lane is staffed and open. | Runs 24/7, including empty-building intrusion. |
| Best at | Stopping a concealed weapon at a controlled entrance. | Seeing a drawn weapon across the rest of the site. |

Evolv Express is a good fit when
- You have one or two high-traffic entrances and need to stop concealed weapons at the door itself.
- Throughput matters, such as a stadium gate or a school arrival rush, and a full metal-detector line is unacceptable.
- You can staff a screener at every active lane to resolve alarms, and you have budgeted that recurring labor.
- You understand the coverage stops at the pedestal, and you have a separate plan for the rest of the site.
Look elsewhere or add a layer when
- You need to cover parking lots, fields, hallways, and after-hours intrusion, which no doorway system reaches.
- You cannot add screening staff at each entrance, which is the real recurring cost.
- You want detection on the cameras you already own without buying and siting new hardware.
- You want published, predictable pricing rather than a per-deployment quote.
The realistic answer for most districts is both, in different places. Put screening where concealed weapons must be stopped at a controlled door, and put camera-based weapons detection for schools on everything else. They fail in opposite places, which is exactly why they pair well.
Evolv Express Questions
Is Evolv Express a metal detector?
Not in the traditional sense. Evolv Express uses low-frequency electromagnetic sensing plus software to flag concealed weapons, and it is designed so people can walk through without emptying their pockets or bags. A conventional walk-through metal detector alarms on most metal and requires people to divest. Evolv aims for higher throughput by classifying weapon-shaped signatures, but that design tradeoff is part of what the FTC scrutinized.
What did the FTC find about Evolv?
The FTC alleged in 2024 that Evolv made unsupported marketing claims, including that Express detects all weapons, ignores harmless items without requiring divesting, is more accurate and faster than metal detectors, reduces false alarms, and cuts labor costs by about 70 percent. Evolv settled without admitting wrongdoing and paid no penalty. The order bars unsupported AI weapon-detection claims and gave certain K-12 customers a cancellation right.
Can schools cancel their Evolv contract?
Some can. The FTC settlement gave certain K-12 school customers the option to cancel Evolv contracts signed between April 1, 2022 and June 30, 2023. If your district signed in that window, you may have a contractual exit worth reviewing with counsel. The cancellation right does not extend to every customer or every contract date, so check your specific agreement.
How much does Evolv Express cost?
Evolv does not publish pricing, and it is sold as a multi-year subscription. A public school district RFP shows a single indoor lane at $78,810 and a dual outdoor lane at $153,290 over 48 months, with the commonly quoted figure of about $2,500 a month, roughly $120,000 per unit, sitting in the middle. Staffing to resolve alarms is a separate recurring cost on top.
Does Evolv Express detect knives?
It is designed primarily around firearms and large metallic threats, and its knife detection has been questioned. Public scrutiny grew after school stabbings in Ohio and New York where Evolv systems were installed but did not catch the blades used. Detection depends on sensitivity settings, which trade off against false alarms and throughput, so no screening lane should be assumed to catch every knife.
Is Evolv Express accurate?
Evolv does not publish a single accuracy percentage, and the FTC order specifically discourages unsupported accuracy claims, so any exact figure you see attributed to it should be treated with caution. Real-world performance depends heavily on how each lane is tuned, the threats it is set to catch, and the human resolving alarms. Accuracy is a deployment outcome here, not a fixed spec.
What is the best alternative to Evolv Express?
It depends on the gap you are filling. For concealed-weapon screening at a door, other entrance systems from CEIA, Garrett, or OpenGate compete directly. For everything past the doorway, camera-based detection covers the site Evolv cannot see. Most sites end up combining a screening lane at one entrance with camera analytics across the rest of the property.
Does Evolv Express replace security cameras?
No. Evolv secures a single entrance lane and has no view of parking lots, fields, side doors, hallways after entry, or an empty building at night. Security cameras and camera-based analytics cover all of that. The two are complementary layers: screening controls a door, cameras watch the rest of the campus and provide the recorded evidence after any incident.
Can AI cameras detect concealed weapons like Evolv does?
No. A concealed firearm produces no visual signature, so no visible-light camera system, including ours, ZeroEyes, or Omnilert, can detect it. Camera AI detects a weapon only once it is drawn or visible. Detecting a concealed weapon requires physical or electromagnetic screening at a controlled entrance, which is the specific job Evolv Express is built to do.
