Alert Verification Performance

Overview

The VSS Alert Bridge verification pipeline processes live RTSP streams through CV detection and analytics (RTVI-CV and video-analytics microservices) and a VLM stage to classify and confirm security alerts. Benchmarks measure end-to-end (E2E) latency, VLM and VST stage latency, and verified alert throughput across the NVIDIA RTX PRO 4500, RTX PRO 6000, DGX H100 SXM, DGX Spark, and AGX Thor platforms using RT-DETR and Grounding DINO (GDINO) with Cosmos3 Nano Reasoner (CR3) precision variants.

All benchmarks use input streams at 1080p, H.264 input.

For dGPU platform tests (NVIDIA RTX PRO 4500, RTX PRO 6000, and DGX H100 SXM), two GPUs were used: one GPU dedicated to RTVI-CV and one GPU dedicated to RTVI-VLM.
