Use this command to select the video source settings for a GigE Vision compliant camera connected through the Gigabit Ethernet interface. The corresponding video driver must be selected in the Video Preferences

If you choose this command, the Video Settings dialog box will appear. Click the Video Source tab, and you will see the following options:

Displays the vendor's name and model of the currently selected camera. If you have more than one GigE Vision camera connected, you can switch to another camera by choosing the corresponding camera name in the list.  
Lets you enable the continuous acquisition mode. If this box is checked, the board will continuously acquire the video into the internal image memory. If the control is visible, the live video will be displayed in the control window.  
Check this box to enable the Multicast mode which allows multiple computers and applications on the network to receive the video feed from the same camera. Only the first instance of ImageWarp that connects to the camera can enable or disable the Multicast mode. All other GigE Vision applications launched in the network can acquire and display the video in the slave mode, but will have no control over the camera settings.  
Acquisition mode
Lets you select the desired acquisition mode from the list. The acquisition mode defines how many frames will be captured when the Acquire option is enabled.  
Use this option to set the number of seconds to wait for a frame to be acquired. Typically used to assign the timeout when the Trigger mode is active.  
Check this box to enable the selected trigger. This mode is typically used with an asynchronously resetable camera. An acquisition will occur upon receiving a signal from an external hardware Trigger Source.  
Trigger Selector
Lets you select the configuration of a trigger signal. The rest of the options in the Trigger group are dependent on this selection.  
Trigger Source
Lets you select the source for the trigger signal. Depending on a camera, there may be one or more hardware trigger inputs as well as the software trigger. If the software trigger is available and selected, the trigger event must be generated by the Trigger command or corresponding script function.  
Trigger Delay
Lets you select the value for the trigger delay which defines the time between the arrival of the trigger signal and its effective activation.  
Trigger Activation
Lets you change the activation mode (trigger signal polarity) for the selected trigger.
