This Security AI Agent Command Center, is a demo of an AI-powered security system that detects objects (like people, bags, vehicles, etc.) in real-time using computer vision.
The live version on Hugging Face is a lightweight demo trained on COCO128 (a general-purpose dataset), while the full version is a more advanced system trained on security-specific data for real-world threat detection.
Key Features:
- Real-Time Object Detection: Identifies objects in images/video (e.g., "person," "backpack").
- Security-Focused: The full version is optimized for threats (e.g., intrusions, unattended items).
- User-Friendly Interface: Simple upload/click-to-run design.
Current Limitations (for the demo):
- Training Data: This demo runs on a general-purpose dataset (COCO128), so it may not catch security-specific threats as accurately as our full version (trained on millions of security-optimized images).
- Video Support: The live video feature isn’t enabled at the Hugging Face demo —but check out my other AI models for real-time object detection in videos and security cameras!
