The injured teenage survivor of a January 2025 shooting at a Nashville, Tennessee high school recently sued the manufacturer of an “AI gun detection” system that failed to detect the handgun that left two dead, including the shooter.

According to the lawsuit, which was filed in Davidson County court last month, the security company Omnilert either knew or should have known that there were “significant operational limitations in its gun detection system that could result in detection failures during actual emergencies, including limitations based on camera placement, proximity of the weapon to camera sensors, camera angle, lighting, and weapon visibility.”

Omnilert cofounder Ara Bagdasarian declined Ars’ invitation to answer questions about the lawsuit. System Integrations, the other defendant in the case, which resold the Omnilert system, also did not respond to Ars’ request for comment.

There’s no AI I think that could have detected a small firearm easily concealed.

The idea with these kinds of systems are meant to allow early warning when possible.

No system is going to be 100%.

Edit: I get the downvotes, but there are people/companies that were/are developing such systems with a genuine intent to make things better. I know, because I was one of them.

The cheap system I have with a Google Coral and FOSS software is pretty good about detecting people and dogs from my camera streams. Sometimes it detects my one dog as a small bear if I haven't cut his hair recently.

Having such systems as a later if defense is good. As the only defense, not so much.

I'm guessing you're using Frigate?

Agreed. The system I had developed was built explicitly as a human-in-the-loop system. It never made any decisions on its own. It was just a tool to enable the existing security staff to have better visibility. That's it.

You can make whatever argument you want about viability and efficacy. The only point I'm making is that our system was just an additional tool for security to use; not the only one.

AI in this context is useless though, you could paint marker "not a gun" on the side of a gun and guess what would happen.

It has some uses, but 95% of what is being used for and 100% of the data centers aren't it.

It would flag it as a gun. How do I know? I worked on and developed a similar system at one point. It worked extremely well. We weren't an American company and ultimately covid killed us (it was US American orgs that were the most interested in our stuff).

Do you think LLMs are being used for this sort of thing? Putting aside the sheer technical mountain of a hurdle that slapping an LLM vision model on top of dozens and dozens of real-time camera streams, the hardware requirements would put the company out of business before they made their first sale.

Computer vision models, which are NOT LLMs, have been around for quite a while now and are very good at doing one thing and one thing only. And they'll do it well for a miniscule fraction of what it takes to run an LLM.

No, datacentres are not being used for real-time gun detection. The company might have other kinds of infrastructure located in a DC, but not the main video processing hardware.
