Video guidelines

To optimize video performance for C•CURE IQ, consider the following guidelines:

  • To improve the network delivery of video data, use a dedicated 10 GB network interface card with a receive buffer size 2048 or greater.
  • C•CURE IQ is compatible with NVIDIA®, AMD, and Intel® Integrated display adapters.
  • For optimum performance and stability, use the following NVIDIA adapters:
    • Recommend NVIDIA P600, NVDIA P620, NVDIA T400, and NVDIA T1000 or higher.
    • Support NVIDIA K620, T400, T1000 or higher for dual monitor support only.
    • Support for NVIDIA K620, T400, T100 or higher for dual monitors.
    • Full support for NVIDIA GeForce® GTX series adapters.
    Note: If you use an NVIDIA P1000 graphics card, for optimum performance, use a single monitor configuration, and ensure that the monitor is connected to port 1 of the graphics card.
  • Testing completed with GEForce GTX 1070
  • NVIDIA Quadro adapters outperform Geforce in testing, and therefore offer better value.
  • GeForce adapters may not achieve the rates published above.
    • 3840 x 2160 (4K) monitor resolution is supported where available.
    • Recommend 1920 x 1080 monitor resolution for integrated adapters.
    • Quad monitor from a single adapter is fully supported.
    • Recommend NVIDIA K1200 or higher.
    • For every monitor attached, each display adapter should have 512 MB of on-board memory available.
    • Always keep display adapter drivers up to date.
  • Video bandwidth consumption is more efficient at lower stream resolutions. This is because there is a CPU penalty for every key frame decoded that also increases with resolution.
    • This penalty is incurred regardless of the frame rate.
  • With mega-pixel cameras at lower frame rates, it is recommended that Variable Bit Rate (VBR) is used or the CBR Bit Rate is proportionally reduced. Otherwise, the bit rate of each frame increases as the frame rate is reduced. No bandwidth savings can be achieved by reducing frame rate unless this is done. This is also relevant for SD resolution cameras.
  • Variations in signal:noise ratio can affect bandwidth and CPU load. This can be especially apparent at night. Live frame rates can be reduced, and the CPU load can increase in such scenarios. Many cameras have functions that can compensate for these phenomena.
