NVIDIA GPUs contain a hardware-based decoder (a chip referred to as NVDEC) which provides fully-NVDEC chips on NVIDIA GPUs provide accelerated hardware-based video decoding for several popular codecs. With complete decoding offloaded to NVDEC, the graphics card and the CPU are free for other operations and you can . This helps to reduce the load on the CPU and/or increase the number of the video cameras displayed on the Client.
In addition, if you have the NVDEC dedicated hardware video decoder running on Servers, you can get video streaming directly to GPU (see Detection tools implementation on processors) for analysis and detection purposes, bypassing RAM.

When decoding with NVIDIA NVDEC chips on portable computers due to the specifics of the devices interaction, the resources of the built-in graphics card will also be used. |
When decoding with NVDEC chips, the following limitations apply:
- Maximum video resolution for the H.264 − format is 4096x4096.
- Maximum video resolution for the H.265 − format is 8192x8192.
- The maximum total frame rate per second for the H.264 codec format is 648 fpsFPS.
To enable decoding with NVDEC chips, do as followsthe following:
- Go to Settings → Options → User interface (1 – In Axxon One, go to Settings → Options (1) → User Interface (2).
- Select Set the Enable hardware decoding checkbox (3).
- Click the Apply button.
Decoding with NVDEC chips is enabled.
