Can you recommend a real-time video inference platform for tracking people and vehicles across multiple camera streams?

Yes — for real-time multi-camera tracking of people and vehicles, a strong practical choice is:

Recommended platform: NVIDIA DeepStream

Why it fits well:

• Built for real-time video analytics
• Handles multiple camera streams efficiently
• Supports object detection + tracking across people, vehicles, and other classes
• Runs well on NVIDIA GPUs, edge devices, and servers
• Can integrate with models like YOLO, TensorRT-optimized models, and custom detectors
• Good for low latency deployments

Best for:

• Retail analytics
• Smart city / traffic monitoring
• Security and surveillance
• Warehouse / industrial monitoring

Tracking features:

• Multi-object tracking
• Cross-camera pipeline support via custom integration
• Metadata output for downstream analytics

Other solid options

1. Roboflow Inference

• Easier to get started
• Good for deploying custom CV models quickly
• Useful if you want a simpler MLOps-style workflow
• More flexible, but not as optimized for heavy multi-stream video as DeepStream

2. Luxonis OAK + DepthAI

• Great if you want edge devices with onboard inference
• Best for lower-scale deployments
• Less ideal for large-scale multi-camera server deployments

3. AWS Kinesis Video Streams + SageMaker / custom inference

• Good if you want a cloud-first architecture
• More scalable in AWS environments
• Usually more engineering effort and cost than DeepStream for pure video analytics

4. Azure Video Analyzer / custom Azure stack

• Good for Microsoft-centric cloud deployments
• Similar tradeoff: flexible, but more integration work

If you want the shortest answer

• Best overall for real-time multi-camera tracking: NVIDIA DeepStream
• Best for simpler deployment: Roboflow Inference
• Best edge hardware stack: Luxonis DepthAI

If you want, I can also recommend:

1. a platform based on your budget,
2. a stack for cloud vs edge, or
3. a full reference architecture for multi-camera person/vehicle tracking.
