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).
- 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)
|
| Codec support | Availability of the required codec in NVDEC | Current support matrix: NVIDIA Video Encode and Decode GPU Support Matrix |
| Compute Capability | 3.5–12.0 (Kepler, 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 (Compute Capability 3.x) are partially supported. We recommend using a GPU no older than Maxwell (5.x).
- You can check the version of Compute Capability of your GPU on the manufacturer's website.
|
| Number of GPUs | Up to four GPUs on one server | IDs: Nvidia GPU 0, 1, 2, 3 (see Selecting Nvidia GPU when configuring detectors) |
| Driver | We recommend the latest stable version from the NVIDIA official website | Outdated drivers may not support the required codec |
For Intel integrated GPUs (decoding)
| Parameter | Requirement |
|---|
| Processor generation | 6th generation Intel Core (Skylake) and higher |
| Codec support | Availability of the required codec in Intel Quick Sync Video |
