Computer vision in security

Ultralytics YOLO models support a wide range of security applications through real-time object detection, tracking, and classification. Common use cases include PPE and workplace safety compliance, people and vehicle detection and tracking, perimeter and intrusion monitoring, access control and license-plate recognition, crowd and occupancy monitoring, threat and prohibited-object detection, and theft or anomaly detection. Because YOLO models can be trained on custom datasets, they’re typically fine-tuned for a specific environment, a factory floor, a parking structure, a retail store, rather than deployed as a generic, one-size-fits-all detector. Most security teams start with a single, well-defined detection task and expand into a broader platform combining tracking, behavior rules, and automated alerts as their needs grow.

Yes. Ultralytics YOLO is built for real-time object detection, making it well suited for live CCTV and IP camera monitoring. It can detect people, vehicles, and objects across video streams with low latency, running on edge devices, on-premise servers, or existing NVR/DVR infrastructure, without needing to send footage to the cloud. This makes it a common choice for security teams that need instant alerts on intrusion, unauthorized access, or unsafe behavior rather than after-the-fact review.

Traditional motion sensors and light-curtain systems detect movement but can’t distinguish between a person, a vehicle, an animal, or debris, which leads to frequent false alarms. YOLO-based perimeter and intrusion detection uses computer vision to classify what triggered the event, apply zone-based rules, and analyze direction or loitering behavior. This reduces false positives significantly and lets security teams set more precise rules, such as alerting only on human intrusion into a restricted zone rather than any motion at all.

Ultralytics YOLO is available under the AGPL-3.0 open-source license or a commercial Enterprise License. If you’re building a commercial security or surveillance product, such as software you sell, license, or operate for customers, and you don’t want to open-source your application, you’ll need an Enterprise License rather than relying on AGPL. This is one of the most common questions from security vendors, since AGPL obligations can require sharing your full application source code if you distribute or host the software commercially.
