6 Web Based Graphical User Interface (WebGUI)
Page 16 / 31
View Live Page
View live page is for visualizing the image the Industrial DashCam is acquiring. This page should be used for
setting focus, choosing field of view and so on.
For starting the acquisition "Start" button, located at the bottom of the page, should be pressed. Stopping
the acquisition is performed by means of the "Stop" button. During the acquisition the "Start" button is
grayed out and vice versa the "Stop" button is grayed out when the acquisition is not running, see Figure 6.
Note, that when the View Live is active, all of the other buttons are grayed out. In order to return onto the
Welcome page, the "Back" button must be pressed.
Figure 6: View Live page. This shows the live view while no acquisition is running. Mouse cursor position is indicated
in "x" and "y" text fields.
By pressing the "Trigger" button a software trigger event can be generated, and the video will be recorded
according to the recording mode set by the user. Even a hardware encoder is not able to create the MP4
video in real time. Therefore, depending on frame rate and length of sequence writing the video will take
several seconds. While writing the video further trigger impulses are ignored.
Text fields "x" and "y" are indicating the mouse cursor position in image-related coordinate system. "fps"
shows the current acquired frames per second. The scale can be selected in the drop-down list in the right-
bottom corner.
"Setup Camera" button opens the Camera setting dialog, which is also available via the Configuration page.
The dialog is for adjusting acquisition parameter, in contrast to the Industrial DashCam parameters as Re-
cording mode, Trigger event types and others. The dialog allows adjusting exposure time, gain, gain per
channel (in case of the Bayer sensor) and the black level. While acquisition is running, the user can change
the area of interest with the sliders below and right of the image.
To make the selected area take effect, press the "Set AOI" button. For the Industrial DashCams equipped
with a strobe, it also provides the corresponding control. Setting a long exposure time might lead to decrease
of the acquisition framerate, therefore please consider opening the aperture or bringing more light into the
scene.
