Camera channels

Camera channels are sourced from camera or video hardware connected through an EX23-R PoE Switch. See Setting up an Axis network camera for more information.

See Video display for viewing and controlling a video channel.

In Test configuration, a camera channel’s parameters may be edited in the Single channel editor.

ClosedGeneric parameters

  • Name: The channel name must be unique and contain valid characters (invalid characters are single and double quotes, '\', '@', '#', '&', '<' and '>'). Invalid channel names are 'true' and 'false' (case sensitive).
  • Description: Enter an optional detailed description of the channel.
  • Collect: Select the Collect checkbox to write the channel data to the SIE data file during a test run.
  • Network node: A CPU serial number shows for a module or camera channel's network node.
  • Custom column information: For each column to be used, enter a unique name for the column header. Select either the “Text” or the “Numeric” sorting option.
  • Network node: Select the network node that will process the video data stream. Since video streams typically consume significant CPU load, pay attention to network node load balancing.
  • Requested frame rate: Set the number of video frames per second to capture and write to the SIE data file.

NOTE
The requested video frame rate will not always be the rate at which frames are actually acquired during a test run. Cameras support discrete sets of frame rates. SomatXR/eDAQXR supported cameras are limited to ones that provide a "best effort" response to the request rate. The meaning of "best effort" is camera type specific; however, the acquired rate will typically be less than or equal to the requested rate.

  • Image size: Set the image resolution in pixels of each video frame captured.
  • Image compression: Set the percentage of compression for each video frame captured.
  • Rotation: Select a rotation angle as desired to show in the channel display from the device. Refer to the device manufacturer's documentation to verify support for rotation; some devices are limited to 0 and 180 degree rotation.

CAUTION
Video streaming is both CPU intensive and data intensive when using multiple cameras. Long tests can easily fill the unit's hard drive or a large number of channels can overload the CPU such that a test is not able to start. If either of these issues occur, reduce the image quality parameters of the camera channels.
