Which GPU for 100 camers in Deepstream?

Accelerated Computing Intelligent Video Analytics DeepStream SDK

Hi

One of my client need to perform video analytics on 100 RTSP camera.
Which GPU is recommended to stream and run inference on 100 RTSP cameras in Deepstream.
And what is the network infrastructure required.
And is single deepstream app capable of streaming and infer on 100 cameras or do we have to create new instance of same deepstream app each with some camera streaming and inference.

The Data center GPU - GA100 should meet this requirement.
Please check Performance — DeepStream 5.1 Release documentation (nvidia.com)

Thanks for the link
Let’s say I take T4 GPU with the system suggested, and set cameras at 30fps and stream type h265, according to document I can stream 64 cameras which utilises 58% GPU.
Couple of questions,
1-Will all 64 cameras run in single Deepstream app and I can access metadata for all in probe function ?
2-if GPU utilisation is 58% can I add more cameras to same or not because of memory constrain won’t be able to add more ?
3-Is it possible to get the network block diagram or any networking details through which these benchmarks were performed to try at our end i.e. to stream 64 cameras ?

which doc do you refer ? Could you share?

Maybe not, you need to check the decoding capability of the GPU - https://developer.nvidia.com/nvidia-video-codec-sdk , e.g. for T4, it can decode max ~2100 fps @ 1080p H265, for 30fps 1080p camera, so it can process max 70 video streams

3-Is it possible to get the network block diagram or any networking details through which these benchmarks were performed to try at our end i.e. to stream 64 cameras ?
what network? Can you please elaborate ?

And what is the network infrastructure required.
Totally depends on your requirement, you may could check TAO networks - https://developer.nvidia.com/tao (https://developer.nvidia.com/tao-toolkit)

Reiterating 64 camera can run, so were they running in Deepstream ?

And regarding network was as to how much bandwidth what type of routers specs, POE switches, but will test and get an idea

Thanks

can you share where you get these info?

Thanks!
