Symptom
The QuickCam Vision Pro may not be displaying video or recording audio in the application you are using.
Solutions
Reboot your Computer
Restarting your computer can help eliminate many detection problems.
1. Make sure your Vision Pro is connected to your USB port
2. Reboot your Mac.
Verify the device in the System Profiler
If rebooting does not help, verify that the computer is detecting the device properly. To do this:
1. Click the Apple Menu in the top left corner of your screen and select "About this Mac".
2. Click the "More Info..." button.
3. When the System Profiler opens, click to highlight the USB option in the left navigation pane and verify that OSX is detecting your camera (see screen shot below)
Set your Vision Pro's Microphone as Default (Audio Issues)
If you are having problems with Audio you should set your QuickCam's built in microphone as the default microphone.
1. Open your System Preferences from either the Apple Menu or your Applications folder
2. Click “Sound” in the System Preferences window (as shown below).
3. Now click the INPUT tab at the top of the window and select the "Unknown USB Audio Device".
4. Once selected, speak into the microphone to ensure the input level is responding.
5. Close the System Preferences once you have verified the microphone is working properly.
Try using the Webcam with a different application
If rebooting your system doesn't fix your problem and OSX is detecting your Webcam in the System Profiler, try using another application supported by your Vision Pro webcam. The links below will direct you to download links an application you want to test your camera with.
Try using the Webcam on another Macintosh Computer
If you have another computer available to you, testing the webcam on a different Mac system may help determine if it is your computer or the camera that is experiencing problems.
