What is USB3 Vision?


  • USB3 interface is subject to a standard for industrial machine vision: the USB3 Vision standard.
  • This standard was officially ratified in January 2013.
  • It is hosted by the AIA (Automated Imaging Association) and serves as the official standard for the USB3.0 interface when used in the image processing industry.

What is the advantage for USB3 interface?
  • Transfer bandwidths up to 350 MB/s
  • Outstanding real-time compatibility
  • High stability and very good error handling
  • Simple integration into all image processing applications (3rd party libraries)
  • Standardization through USB3 Vision
Why my USB3 camera cannot reach maximum frame rate (fps)?
  • Exposure time will slow down camera speed, please check on it.
  • By default, Basler camera will limit the camera’s speed to 50% of the maximum speed. So by turning off the camera’s bandwidth limitations can let your camera run on full speed.
  • Basler’s pylon USB Configurator tools can help you troubleshooting your issue.
Why does a Basler ace USB 3.0 camera not work on a USB 2.0 port?
  • The reasons for that is more physical than a product-related. All USB 3.0 camera vendor do have the same issues: At first USB 2.0 is mainly specified for 500mA of current while USB 3.0 port does offer 900mA. Depending on the sensor, USB 3.0 camera must be supported with far more than 500mA. Therefore, there is not enough power over one cable. Another reason will be the performance of USB 2.0 is massively different to USB3 Vision. The protocol itself is less stable, the CPU load far higher and the real-time capability worse. Altogether you would limit an USB 3.0 camera with a connection to an USB 2.0 port.
What is GigE Vision?
  • GigE Vision is an interface standard introduced in 2006 for high performance industrial cameras.
  • It provides a framework for transmitting high-speed video and related control data over Ethernet networks.
What is the transfer bandwidths for GigE Vision?
  • In computer networking, Gigabit Ethernet (GbE or 1 GigE) is a term describing various technologies for transmitting Ethernet frames at a rate of Gigabit per second (1,000,000,000 bits per second), as defined by the IEEE 802.3-2008 standard.
  • GigE Vision standard transfer rate is 1 Gigabit per second (1 Gbps)
  • 8 bits= 1 Byte (8b = 1B)
  • GigE interface transfer rate is equal to 1 Gbps or 125 MBps.
What is the differences between “C-Mount” and “CS-Mount”?
  • “C-Mount” lenses have a flange back distance of 17.526mm whereas “CS-Mount” have 12.5mm.
  • “C-Mount” lenses can be used on “CS-Mount” cameras by utilizing a 5mm adaptor.
Can CS-Mount camera use C-Mount lens?
  • Can, use a 5mm spacer ring together with the C-Mount lens and connect to the camera.
