How to troubleshoot Webcams in Windows Vista?
If you are having difficulty getting the webcam to work, review the tips about using a webcam, and then follow the troubleshooting actions in this article.
Step 1: Close all software before starting a new webcam session
Do not enter standby and then wake the system immediately, before the power light turns yellow. If so, the webcam may not function correctly until the computer is restarted. To avoid this issue, allow the system to fully enter standby before waking up the system.
If you installed the webcam separately (it did not come with your Vista PC), make sure the webcam drivers and software are compatible with Windows Vista.
If you are using an external webcam, make sure you install any webcam software from the CD before you plug the webcam to your computer. Without the software, the webcam may not be recognized by your computer and this can cause error messages.
If the display is blank, the camera may have timed out. Turn the camera on again.
If the camera does not display Connected to computer, disconnect and then reconnect your camera.
Make sure the camera is set to Digital Camera in USB Configuration when trying to download images through some software.
Test your webcam in a different application to confirm if the issue is specific to that application. If the webcam functions properly in a different application, then contact the manufacturer of the video software for the latest drivers and for specific troubleshooting instructions.
If you have an external webcam, test it on another computer. If it functions properly on a different computer that has the same operating system, then you may need to install hardware drivers for your computer to work with the webcam.
If an external webcam fails to work on several computers, your webcam may be defective. Contact the webcam manufacturer for specific diagnostic information and troubleshooting instructions.
Your webcam may not work properly across some network firewalls. If you have trouble viewing or sending video to someone on another LAN or outside the network firewall, refer to the support information for the firewall or contact a network administrator for assistance.
Dial-up Internet connections often lack the data transfer capacity to handle both video and voice simultaneously. A broadband Internet connection is highly recommended for video messaging. Performance varies with dial-up connections.
For the best webcam experience, close all other applications and background tasks, and limit your Internet browsing or streaming to preserve bandwidth.
Sometimes after you finish using the webcam in a software program, the program may not properly release the webcam for other activities in other applications, or even the same application. Sometimes you cannot use the webcam because it is being accessed by another program by default. So, if you are having a problem with your webcam, close the program you are using it in and then restart the same program or open a different program.
Step 2: Restart your PC
Sometimes, closing the software application that was using the webcam is not enough. Some webcam software cannot close the webcam for other applications to use later. When this happens, the webcam cannot be used by any other application until the computer is restarted.
Step 3: Select the webcam in your video viewing software list
Make sure USB 2.0 Camera or your Webcam is selected as the video input source in the software you are trying to use. The various software programs that can use the webcam use different terms for describing a video source and the option to select it can vary. Usually, camera, webcam, or video settings can be found in the preferences or properties pages for the software that uses the webcam.
If your PC includes a TV tuner, often the TV tuner is the default video input device. So, for example, if you are using Windows Live Messenger to have a video chat with your webcam, you need to select the your Webcam as the active input device because the TV tuner is the active video input device by default.
Example: Select webcam in Windows Live Messenger
To select the webcam as the default video input device in Windows Live Messenger:
1. Open Windows Live Messenger.
2. Click the arrow
icon on the Windows Live Messenger toolbar.
3. Select Tools
and then Audio and Video Setup
4. Click Next
, and then Next
5. In the "Select a Webcam you would like to use" dropdown list, select the name that corresponds to the webcam that is installed on your PC (such as USB 2.0 Camera
6. Click Finish.
Step 4: Download the latest drivers and updates for your webcam and your video software
Some webcams may not be recognized by some software programs unless you have the most recent drivers and updates for your webcam hardware and webcam video software. Also, if the video footage from your webcam is in a format not supported by your video software, you may need a third-party plug-in or utility to view or convert the video footage to a format supported by your webcam video software.
Step 5: Make sure you have the correct Vista drivers installed
If you installed the webcam separately, go to the webcam manufacturer's website and download the latest drivers, updates, plug-ins, or conversion utilities for any webcam video software. Make sure the webcam drivers and software are compatible with Windows Vista!
If you are having problems getting the webcam to be recognized by video playing or editing software, go the software manufacturer web site to find and install any updates or patches.
Check Windows Update for any Vista-related drivers that may affect your webcam and your video software. Click the Start button, All Programs , and then Windows Update
If you are having problems hearing sound or using your webcam, try the following steps.
Make sure you have installed the correct Vista drivers and not the generic sound driver in Windows. If you have installed the generic sound driver, uninstall the webcam video software and download and install this Vista sound driver, and then reinstall your webcam video software.
