What is the recommended hardware for Stream?

The recommended hardware for Stream is as follows:

CPU.  The main drivers of CPU utilization is the amount of vehicles observed by Stream.  No GPU is needed.  See examples of machines with a certain Passmark score.

  • For High Traffic (e.g. highway, busy street): CPU Passmark Score = 700 * # Stream Cameras.
  • For Low Traffic (e.g. parking entrance, small street): CPU Passmark Score = 350 * # Stream Cameras.

To figure out the Passmark of an existing machine, just do an online search!  This Gogole Search: “intel i5-8250u cpu @ 1.60ghz passmark” returns Passmark 6064.

RAM.  The main drivers of RAM utilization is the video size and Vehicle Make Model Color (and Orientation) identification.

  • 1920×1080 video with MMC: RAM = 500M * cameras.
  • 1920×1080 video without MMC: RAM = 400M * cameras.
  • 1280 x 720 video with MMC: RAM = 450M * cameras
  • 1280×720 video without MMC: RAM = 350M * cameras.

Hard Drive Space.  Stream has a fairly small footprint.  The main occupants of the hard drive will be the jpg images captured and CSV from the ALPR. If you have 0.5 GB of storage, that would be plenty. 


  • Nvidia Jetson Xavier AGX with GPU can support 3 Stream cameras with MMC.
  • For 2 Stream camera with MMC deployment, Intel Core i5-4200U @ 1.60GHz (Passmark 2185) with 2 GB RAM should be very sufficient.
  • For a 20 Stream camera deployment for highway monitoring with Vehicle MMC, you will want a machine with 14000 Passmark Score, such as an Intel Core i9-10880H @ 2.30GHz.  This machine will need 1 GB of RAM.
