6.7 Network Camera Input Channel
Use the network camera message channel to acquire input from an Axis 211 network
camera. The camera must be properly configured as outlined in
“Network Camera
Configuration” on page 102 .
NOTE
To find the channel configuration options specific to the network camera, click the
Message Channel Specifics button on the channel configuration window.
NOTE
To view the captured images in InField, add the camera input channel to a Time
History DataMode. For more information on viewing the data in InField, refer to the
Axis Network Camera Devices Quick Start Guide.
Output Data Type
The output data type is always 8-bit unsigned message. Use the message logger
DataMode to store message data. For more information on the message logger, see
“Message Logger” on page 168 .
Size
Select the size in pixels of the recorded images as one of six standard image sizes
from 160 by 120 to 640 by 480 pixels. The default size value is 640 by 480 pixels.
Compression
Set the percent compression for the camera JPEG images to between 0 and 100%.
The default compression value is 60%.
Frame Rate
Set the frame rate in hertz to the maximum camera images per second stored by the
eDAQ
lite . The frame rate must be between 1 and 30 Hz. The default frame rate value
is 30 Hz.
NOTE
The frame rate as set is the maximum frame rate. The actual frame rate may vary
depending on network efficiency, eDAQ
lite load and the size and compression
settings. Changing the size and compression values may allow the eDAQ
lite
to
achieve the maximum frame rate. On an unloaded eDAQ lite with no network
problems, the default camera message channel settings produce a true 30-Hz frame
rate.
