Evolv’s AI gun scanner is gaining popularity

When Peter George saw the news of the mass shooting at the Tops supermarket in Buffalo on May 14, he had the thought that he had often had after such tragedies.

“Could our system have stopped?” he said. “I do not know. But I think we could democratize security so that someone who wants to harm people doesn’t go to an unexpected place. “

George Evolv is the CEO of Technology, an AI-based system for marking weapons to “democratize security” so that weapons are kept out of public places without elaborate checkpoints.

US gun violence in Buffalo and now in Uvalde, Texas is on the rise – gun sales were on record in 2020 and 2021, while the Gun Violence Archive reports at least 198 mass shootings since January – Evolv increasingly has become more popular, used. schools, stadiums, shops and other gathering places.

Its growing use was a relief in schools on Tuesday with the Robb Elementary School shooting that claimed the lives of at least 21 people, including 19 children.

For its proponents, the system is a more efficient and less attractive alternative to the old metal detector to make events safer and more enjoyable. For its critics, however, the effectiveness of Evolv has hardly been proven. And it opens a Pandora’s box of ethical issues, where convenience is paid for with the care of RoboCop.

“The idea of ​​a nicer, smoother metal detector is theoretically a nice solution to these horrific shootings,” said Jay Stanley, senior analyst for the U.S. Civil Liberties Union’s speech, privacy and technology project. “But do we really want security to create more ways to invade our privacy? Do we want to turn every mall or league game into an airport?

Evolv machines use an “active sensor”, also a light-emitting technique holds to create radar and lidar images. He then applies AI to study them. Waltham, Mass., The company’s data scientists, have created “signatures” (basically visual shots) and trained AI to compare them to scanner images.

Executives say the result is a smart system that can “see” a weapon without anyone stopping and emptying their pockets in a beep machine. When the system identifies a suspicious item as it passes through a group of people, it draws an orange color in a live video feed of the person surrounding it. Only then will a security guard approach him, watching him on a nearby tablet, to make his performance more appealing.

Dan Donovan, a veteran security consultant who rents out Evolv’s system for events, says that by allowing guards to focus on fewer threats, it avoids the fatigue that metal detector operators can feel. Like other advisers, he probably wouldn’t have stopped the system when the Buffalo shooter started firing in the parking lot.

Consumers can expect to see much more of Evolv. It is now used by sports franchises like the Tennessee Titans and Carolina Panthers; so do the New York Mets and Columbus Crew. In February, the Super Bowl at SoFi Stadium opened on an outer perimeter. In New York, public art institutions like Lincoln Center are trying. There is also a municipal hospital. (NYC Mayor Eric Adams has touted it as a potential subway security measure, but small spaces and interference from underground signals make this no more credible. Airports, which meet stricter standards, are also unlikely).

The Charlotte-Mecklenburg school system in North Carolina, with 150,000 students, has licensed Evolv. Theme parks are also excited: all 27 Six Flags parks across the country are now in use. Evolv has now completed 250 million studies, up from 100 million in September.

George believes that accuracy and lack of friction make Evolv compelling. “No one has a prison or airport wherever they want to go, and that’s what you have with a dumb analog metal detector,” he said. “And the cost of doing nothing is rising day by day.”

The company, which went public last year, has raised at least $ 400 million from investors Jeb Bush, Bill Gates, Peyton Manning and Andre Agassi. (The space is growing, with a system of Italian rival CEIA also gaining popularity.) Based primarily on the four-year subscriptions it sells, Evolv doubled its revenue in the first quarter by $ 8.7 million compared to 2021, but also more than more. it doubled its losses to $ 18.2 million.

Retail stores are attractive use cases, George said, because people want to feel safe shopping, but don’t want to stop and control every time they go in to buy some food. (About 60 people can be scanned every minute, Evolv says.) George said he caught 57 guns in the first four hours when a system was installed in a mall near Atlanta, Lenox Square, in January.

Overall, George said, Evolv scored at least 15,000 guns in the first quarter of 2022. (These numbers have not been publicly verified).

But IPVM, a trade in the security industry the publication, after a review, concluded that Evolv “has the basic technological limitations to distinguish benign objects from real weapons.” One problem, IPVM said, citing the company’s analysis, is that some metal objects confuse AI, including ruggedly designed Google Chromebooks.

IPVM says Evolv did not provide enough data. The publication also states that the company will not contact him due to his inquiries; says the company has also asked it to stop reporting Evolv on behalf of public safety.

In a statement to The Washington Post, Evolv said: “We believe that publishing a security protection technology plan is irresponsible and makes the public less secure, giving unnecessary insights to those trying to use it to harm information.”

Alan Cowen, a former Google scientist and AI expert, says he would also be concerned about “conflicting examples” in which bad actors learn to avoid AI – say by putting tape around the handle of a gun – as well as delays. guess this because Evolv won’t mark it.

Some techno-ethicists say that accuracy is the only fear.

“If it reduces false positives while capturing real positives, that seems like a benefit,” said Jamais Cascio, author and founder of Open the Future, an organization that studies the effects of technology. “My concern is what happens when a concert goes beyond the search for weapons: when someone decides to add all sorts of tickets to the person being scanned, or if we join a protest and a government agency can use and monitor the system. Sign with us. We know a metal detector “What we can say and what we can’t do. We don’t know how to use that.”

George says no data is applied to a scanned subject and no information is captured or cataloged. In terms of accuracy, he admits that the Chromebook has been a problem, but says the algorithm is improving. He suggests that students simply realize that they need to keep on their way to school, at a low price. “Why shouldn’t there be a system so that children can learn safely and get in without breaking the bank?” he asked.

However, it remains to be seen whether this will be possible in large neighborhoods such as Charlotte-Mecklenburg. Requests for comment from the district security police were not returned.

Several Evolv customers told The Post that they were happy with the system.

“We’ve gone from 30 lines of metal detectors to four lanes, and we’re not going to stop people for every cell phone or home key,” said Jason Freeman, Six Flags’ vice president of safety, security, health and the environment. He said the overall stoppage has gone from 32 per cent to 15 per cent, with the vast majority still not considered a threat. The idea is not just to catch more weapons; everything else is a waste of less time.

Mark Heiser, director of the Denver Performing Arts Complex, says the system is light years ahead of the metal detector. “We will never go back,” he said.

Heiser mentioned fewer alarms for items like pen knives – “it’s good because it allows us to focus.” [the more destructive weapons]”. And, he points out, many listeners feel freer to walk in it.

But ACLU’s Stanley remains unconvinced.

“It’s good to have subtle devices. But they can also be more insidious or annoying, ”he said. “A lot of people will be surprised if an umbrella tucked inside a coat pocket suddenly encounters a security guard.”
