Question: What aggregate single-model throughput is required for 50 cameras?
|

Takeaway: Requirement scales from 50 infer/s at 1 fps to 250 infer/s at 5 fps;
|

|
|
the measured serial PyTorch reference is below even the 1 fps workload.
|

Family: comparison, horizontal bar. Palette: one blue root plus a gold reference.
