MouthWatch Initial Setup
Connect the camera to the target station via USB and confirm that the “Cameras” category in Device Manager appears with USB Video Device within the category.
Open XVCapture/DCV and move to the capture window, go to Video Devices and ensure that USB Video Device is selected. Then go to Video Options and select “Still Pin and Other Video Sizes”. Under “Still Pin Capture” click “I want to capture video from the still pin” and ensure the circle is selected and then pick a size from the dropdown then hit “OK”. Test the camera to ensure functionality.
MouthWatch Camera Capturing Image Twice on Physical Click
If MouthWatch cameras are capturing the image twice when pressing the capture button, you can adjust the settings inside of the MouthWatch application to correct this. Choosing VixWin from the list of available imaging software will often correct this issue and make the physical capture button return a single image.
MouthWatch Camera Not Displaying Live Preview
If a MouthWatch camera is connected, and selected as the active video source, but no live video preview is displayed, from the DirectVideo window go to:
Advanced Options > MPEG2
Clicking "MPEG2" should allow the live preview to immediately display. Clicking the option again turns the live preview off once more.
MouthWatch Camera Could Not Initialize Video Error
The only known “fix” is a clean reinstallation of the operating system.
MouthWatch "80070005" Error After Initial Install
If you receive this error message after a new MouthWatch camera has been installed, try opening the Windows 10 Privacy settings (Settings > Privacy) and allowing all applications to access the camera. This seems to allow the camera to be seen by external applications including XVCapture and AMCap.
