If detection tools use GPU for video decoding (see Processors used for detectors operation), the following hardware requirements must be met:
These requirements apply if you select hardware video decoding in the settings of detectors or client display (see Processors used for detector operation, Configuring hardware video decoding for display on the Client).
| Note |
|---|
|
- Video decoding (NVDEC) is used both to power detectors (during hardware decoding of the input stream) and to render the GUI in the client if you enable the Enable hardware decoding parameter (see Hardware-based decoding with NVIDIA NVDEC chips). Decoding requirements are the same for both cases. Video decoding works on GPUs up to and including Kepler/Maxwell/Pascal in all versions of Detector Pack 3.14–3.15 and later.
- Neural analytics is the execution of neural network algorithms. GPU requirements for inference can vary (see Hardware requirements for neural analytics operation). Starting with Detector Pack 3.15.2, support for Pascal (10 series) and later GPUs has been discontinued.
- Decoding and neural analytics can run on different GPUs in the same system.

For NVIDIA GPUs (decoding)
| Parameter | Requirement | Comment |
|---|
| CUDA version | - 11.1–11.8 (for Detector Pack 3.14–3.15.1)
- 12.8.1 (for Detector Pack 3.15.2 and later)
| - Updating CUDA does not require replacing the GPU.
- nvidia-smi displays the CUDA version supported by the current driver. For decoding to work, the driver must support the specified version (or a newer version within the major compatibility range)

CUDA is compatible with generations of computers with the following architectures: Kepler (partially)| , Maxwell, Pascal, Volta, Turing, Ampere, Ada Lovelace, Hopper, and Blackwell (see CUDA)) | - Decoding is preserved on all listed architectures in all versions of Detector Pack.
- Kepler-based GPUs (
