Scylla Weapons Detection System AI Gun Detection Reviewed: How It Works, Accuracy, and Cost
Scylla runs visual gun detection as software, with an option most rivals do not offer: a fully air-gapped, on-premise deployment that sends no video to the cloud. This review covers how the system works, what its 96% accuracy and 15-meter range figures actually assume, how the cost is set, and where a buyer is better served elsewhere. We sell a competing product, so every claim below is sourced to Scylla's own materials.
What Is the Scylla Weapons Detection System?
Scylla weapons detection is an AI layer that watches security camera feeds and flags a visible firearm. Its defining feature is deployment: alongside a cloud option, Scylla runs fully air-gapped and on-premise through its Asteria edge appliance, so no video ever leaves the site. That makes it the natural pick for government, defense, and regulated buyers who cannot send footage to a vendor's cloud. Scylla states its platform is NDAA section 889 compliant and US DoD validated, with field testing at US Army installations.
Scylla does publish an accuracy figure, and the conditions on it matter. It cites a probability of detection exceeding 96% under real-world conditions from US Army field testing, a false alarm rate of less than 0.1 alerts per camera per day, and an effective range of roughly 15 meters on standard Full HD cameras. Those are three different numbers with three different meanings, and the range condition in particular decides whether the system works on your cameras. Scylla is detection-only: unlike ZeroEyes, there is no staffed operations center, so your team verifies and responds. Scylla publishes no price list.

How Scylla Gun Detection Works
The detection pipeline is the visual approach the whole category shares. What Scylla does differently is where the processing happens and who is responsible for the alert once it fires.
Your cameras keep streaming
Scylla runs on existing IP cameras. There is no camera swap, which is the standard commercial argument for software-based detection: you add a threat layer without a new hardware fleet.
Detection runs at the edge
With the Asteria edge appliance, processing happens on-premise and fully air-gapped, with no cloud dependency and no video leaving the site. This is the feature government and defense buyers pay for, and it is Scylla's clearest point of difference.
The model flags a visible gun
Scylla says it needs as little as 100 milliseconds of video, up to a maximum of one second, to classify a firearm, at roughly a 15-meter range on standard Full HD cameras and further on higher-resolution ones.
Your team verifies and acts
Scylla is detection-only. Its own FAQ states human operators remain responsible for verifying alerts and making all operational decisions. There is no ZeroEyes-style monitoring center included; the verification labor is yours.
The architectural takeaway: Scylla is a detection engine you run, not a managed service. It reads the feed, flags a gun, and raises an alert into your own security operation. That suits an organization with a staffed control room and a hard requirement to keep video on-site. It suits less well a small team with no one to watch the alerts, which is the tradeoff to weigh against a human-verified service. Our comparison of gun detection software lines up the managed and self-run models side by side.
What Scylla's 96% Accuracy and 15-Meter Range Actually Mean
Scylla is one of the few vendors that prints real numbers, which is to its credit. But the numbers travel with conditions, and dropping those conditions is how a spec sheet becomes a false expectation.
| The claim as repeated online | What Scylla actually says | Why it matters to you |
|---|---|---|
| "96% accurate gun detection" | Scylla cites a probability of detection exceeding 96% under real-world conditions, from US Army field testing. | That is a detection probability from a specific test program, not a guarantee on your cameras. Your resolution, angles, and lighting move the real number. |
| "Almost no false alarms" | Scylla states less than 0.1 alerts per camera per day, which is a false alarm rate, a separate metric from detection accuracy. | A quiet system and an accurate system are two different things. Ask for both numbers; a detector can be silent and still miss. |
| "Works across your whole site" | Effective range is roughly 15 meters on standard Full HD cameras, farther on higher-resolution ones. | Range is conditioned on camera resolution. A target 30 meters out on a 1080p camera is outside the tested envelope. Placement is part of the product. |
| "Detects anyone with a gun" | Like every camera-based detector, Scylla identifies a firearm only once it is visible on camera. | A concealed or holstered gun has no visual signature. Visual AI is not a screening lane, and no vendor here changes that. |
None of this makes Scylla a weak product; if anything, publishing a conditioned accuracy figure and an independent test source is more transparent than the vendors who publish nothing. The point for a buyer is to compare like for like. Detection probability under stated conditions, false alarm rate, camera resolution and range, and who verifies the alert are four separate questions, and a quote that answers only one is not comparable to a quote that answers all four.
The concealed-weapon limit applies equally to us, to ZeroEyes, to Actuate, and to every camera-based detector. If your threat model is a hidden firearm carried through an entrance, that is a screening problem handled by a walk-through system, and we cover the economics in the Evolv weapons screening pricing guide.
Scylla Cost: What Moves the Quote
There is no Scylla price list. Like the rest of the gun detection category, it is quoted per deployment, and the edge-appliance option adds a hardware line most cloud-only rivals do not have. These are the inputs that decide your number.
How many cameras you enable
Visual gun detection is billed against camera count, and the per-camera rate typically falls as the count rises. Signed contracts elsewhere in this category range from roughly $592 per camera per year at 38 cameras down to about $168 per camera per year at 650 to 800 cameras, which is the shape to expect in negotiation.
Edge appliance or cloud
Air-gapped, on-premise deployment via the Asteria edge appliance adds hardware and setup that a cloud-only detector avoids. It is the reason a defense or government buyer chooses Scylla, and it is also a real capital line in the quote.
Which detection modules
Guns are one module. Scylla also sells behavior, intrusion, and fire and smoke detection, each with its own line. A quote for gun detection alone is not comparable to one that bundles several analytics.
Compliance and integration scope
NDAA 889 and DoD-validated deployments into government infrastructure carry integration, security review, and support requirements that a commercial rollout does not. Those requirements move both the price and the timeline.

Scylla vs the Other Weapons Detection Systems
All five below detect a visible firearm on camera. They differ on where the processing runs, who verifies the alert, and whether you can learn the price without a sales call.
| System | Built for | Deployment and verification | Published price |
|---|---|---|---|
| Scylla | Government, defense, and regulated sites needing on-premise or air-gapped processing | Edge or cloud; NDAA 889 and DoD validated; verification is the customer's job | No |
| ZeroEyes | Schools, campuses, and enterprises wanting a fully managed weapons-detection service | Cloud; its own 24/7 human operations center verifies every alert; SAFETY Act Designated | No |
| Actuate | Central monitoring stations, alarm receiving centers, GSOCs, managed service providers | Cloud; human verification via central-station partners as a paid layer | No |
| Omnilert | Schools and campuses wanting detection plus mass notification in one system | Cloud or appliance; human verification and PSAP dispatch bundled; SAFETY Act Designated | Partial |
| Surveillant | Businesses that want detection on their own cameras without a procurement cycle | Cloud; you review detections in-platform; person, vehicle, weapon, intrusion, and plate analytics | Yes, $39 to $42 / cam / mo |
Where Scylla genuinely wins: if you cannot let video leave your own infrastructure, Scylla is close to the only serious answer in this list. The air-gapped Asteria appliance, NDAA 889 compliance, and DoD validation are exactly what a defense installation or a security-cleared facility needs, and no cloud-first competitor can match that posture. Its published accuracy testing is also more transparent than most.
Where a buyer should look elsewhere: if you have no control room to watch alerts, a detection-only tool leaves a gap that a human-verified service like ZeroEyes fills. And if you want detection plus video management on your own cameras at a price you can read today, that is the model we publish. Our Scylla AI alternative page walks through the difference.
Scylla Weapons Detection: Questions
How accurate is Scylla gun detection?
Scylla cites a probability of detection exceeding 96% under real-world conditions, drawn from US Army field testing, along with a false alarm rate of less than 0.1 alerts per camera per day. Those are two separate metrics: one is how often it catches a visible gun, the other is how rarely it cries wolf. Both come from Scylla and its testing partners, and real performance on your site depends on camera resolution, angle, lighting, and distance to the target.
Does Scylla work with my existing security cameras?
Yes. Scylla runs as software on existing IP cameras rather than requiring a new camera fleet. It cites an effective range of roughly 15 meters on standard Full HD cameras, and greater distances on higher-resolution cameras, so camera placement and resolution matter to whether it detects a firearm reliably at the distances you need to cover.
Can Scylla run on-premise or air-gapped?
Yes, and this is its main differentiator. Through the Scylla Asteria edge appliance, detection runs fully on-premise and air-gapped, with no cloud dependency and no video leaving agency-controlled infrastructure. That is why Scylla suits government, defense, and regulated environments that cannot send footage to a vendor cloud, and it is backed by NDAA section 889 compliance and US DoD validation.
Can Scylla detect a concealed weapon?
No. Like every camera-based detector, Scylla identifies a firearm only once it is visible on camera. A gun inside a bag, pocket, waistband, or holster produces no visual signature, so no visual AI system can find it. Detecting concealed weapons requires a physical screening system at an entrance, which is a different product category entirely.
Does Scylla include a human monitoring center?
No. Scylla is detection-only. Its own FAQ states that human operators remain responsible for verifying alerts and making all operational decisions. Unlike ZeroEyes, which staffs its own 24/7 operations center to verify every detection, Scylla hands the alert to your team, so you need a control room or monitoring arrangement to act on what it finds.
How much does Scylla weapons detection cost?
Scylla does not publish pricing. Quotes are built per deployment from your camera count, whether you choose the edge appliance or cloud, which detection modules you license, and the compliance and integration scope. As a category benchmark, per-camera rates in signed public gun-detection contracts have ranged from roughly $592 down to about $168 per camera per year as camera counts rise.
