On this tab the user can define all settings regarding capturing pictures from WolfVision devices, the picture detail level, how the picture will be displayed in the application window and for EYE-12/SCB-12 devices it's also possible to configure the "Trigger" functionality.
The picture capture settings are especially important and most used by users of the application. The best settings for good performance for a specific user application are often a resolution/quality versus frame rate issue, especially in Continuous View mode. Higher resolution/no compression means lower frame rate due to the higher amount of data which has to be transferred over the connection link which has a limited bandwidth of approx. 480 Mbps (USB 2.0) or approx. 100 Mbps (Ethernet/LAN). Compressed picture transfer with the native picture resolution normally provides the best results for most applications.
To recall the default settings for this dialog tab, click "Reset settings". The other tabs of the "Preferences" dialog box will not be affected.
The settings in this group box are only used by the "Still Image" capture mode.
You can change the resolution of captured pictures from the connected device. Possible resolutions depend on the connected Visualizer model.
When checking the box, the captured pictures will be transferred as JPEG compressed pictures. You can adjust the picture quality by moving the "Picture quality" slider to the desired position (four quality levels are available). A lower picture quality will result in a higher compression level of the picture which will reduce the amount of data to be transferred over the connection link. This will automatically increase the frame rate but the picture quality will be decreased.
The settings in this group box are only used by the "Continuous View" capture mode.
The "Continuous single picture transfer" mode is available for all Visualizers/cameras which are connected over USB or Ethernet/LAN. For certain devices connected over Ethernet/LAN the "UDP multicast stream transfer" is also available.

UDP multicast stream transfer(Motion JPEG)
The UDP multicast stream transfer settings are only available for devices connected over Ethernet/LAN which do support this transfer method. In order for the multicast stream to work properly, the firewall and network settings have to be adjusted to allow UDP data transfer through the ports mentioned in the important notice below the "Frame Rate" slider. Ask your network administrator for more details. If the connected device supports this transfer mode it's the most suitable way to capture pictures from the Visualizer/camera. The best setting for "Capture Resolution" depends on your needs. A higher capture resolution will result in a lower frame rate. The used bandwidth of your network can be defined with the "Frame Rate" slider. It also depends on the selected capture resolution.

Tells the device how much bandwidth it should use for sending out the UDP multicast stream. A higher frame rate results in higher network traffic.
Different resolutions, compressed picture transfer and multicast stream transfer (Motion JPEG) are only supported on following device models:
EYE-12 and SCB-12 - all units
VZ-8plus4 - all units
VZ-9plus with serial number #1008068 and higher
VZ-9plus³ - all units
VZ-9.4L - all units
VZ-9.4F - all units
VZ-C6 - all units
VZ-C12² with serial number #1009412 and higher
VZ-C32 with serial number #1011797 and higher
VZ-C12³ - all units
VZ-C32³ - all units
VZ-C3D - all units
VZ-P18 - all units
VZ-P38 - all units
vSolution Cam - all units
Otherwise there is just the choice between "Fullview" (equals native resolution) and "Preview" mode (50% of native resolution) without any compression:
VZ-8
VZ-8light
VZ-8plus
VZ-8light²
VZ-8plus²
VZ-9
VZ-9plus with serial number lower than #1008068
VZ-27
VZ-27plus
VZ-27plus²
VZ-57
VZ-57plus
VZ-C10
VZ-C11
VZ-C12
VZ-C12² with serial number lower than #1009412
VZ-C32 lower than #1011797 and higher
Changing this setting will change the sharpness/contrast of the captured pictures from a Visualizer/camera. This setting does not only affect the pictures captured over USB or Ethernet/LAN but also the HDMI/DVI/VGA outputs of the device.
Detail setting is not available on the Visualizer model VZ-57.
This setting controls the way a captured picture is displayed in the main window of the application. There are three different modes available:
Keep aspect ratio: You can resize the application window but if you release the mouse button the application will resize your selected window size to maintain the original aspect ratio of the displayed picture.
Fit to window: You can resize the application window in any direction and if you release the mouse button the displayed picture will get stretched to fit in the new window.
1:1: You can't resize the application window because the size of the window is dictated by the selected "Capture Resolution". The size of the window is adjusted to the same resolution as the selected "Capture Resolution". To prevent cropped pictures, the computer screen resolution should be higher than the selected "Capture Resolution". If your screen resolution is not high enough to display captured pictures without cropping them a message box will inform you about this problem.
With activated trigger mode, the application will capture only those pictures from the device which were taken in response to a trigger event. The trigger function can be used for automated capturing.
For more information about the trigger function, please read the user manual of your WolfVision device.
Trigger mode function is only available with camera models EYE-12 and SCB-12.
