To ensure optimal performance, do not exceed the maximum number of cameras that can be viewed on each client workstation type in Security Center 5.12.

The maximum number of camera streams supported by each client workstation profile is as follows:

1 Maximum number of streams at full capacity (85% CPU and GPU utilization) in a static environment (video wall). Reducing the number of streams is required based on the use of other features such as visual tracking or guard tours.
NOTE: In an active operator scenario, the maximum number of decodings should not exceed 95% of these numbers. The numbers in the previous table are obtained under the following conditions:
  • Full HD (1080p) monitors are used for all tests.
  • Two monitors are used when more than 64 tiles are required.
  • Low-motion video scenes are used on all cameras.
  • The rendered frame rate could be reduced to a minimum of 10 fps.

GPU considerations

  • NVIDIA® card with CUDA compute capability 5.0 or higher is recommended.
  • NVIDIA®-SLI™ bridge not supported.
  • If your Intel® processors support Intel® Quick Sync Video, this technology can also be used provided the monitor is plugged into the motherboard. Laptops can also use Quick Sync Video.
  • Two or more graphics cards can be used to support different monitors individually. To have the video decoding done on the card, at least one monitor must be connected to each card.
  • Activating hardware acceleration can generate a slight video decoding delay.

Encryption impact on workstation performance

Video encryption can increase the CPU usage by up to 40% when viewing low-resolution video (CIF). As the resolution of the video increases, the impact is less noticeable because it takes more processing power to decode video than to decrypt video. The impact on performance becomes negligible for HD and Ultra-HD video.

Watermark impact on workstation performance

Video watermarks are rendered by the client workstation. This extra load reduces the maximum number of live and playback video streams that can be displayed simultaneously. On average, the maximum number of tiles that can be displayed when hardware acceleration is enabled is reduced by 10%. This reduction reaches 30% on machines without hardware acceleration. The performance impact increases with the video resolution.
