Why doesn't the camera work?

Camera can not use is a lot of network friends encounter a lot of a problem, especially for novice friends are often encountered. Camera can not be used in fact is nothing but software problems or hardware problems, as long as the understanding of its working principle and troubleshooting methods, can generally solve the problem. The following author according to different causes of the camera can not provide a corresponding response method, I hope to encounter such a camera fault friends have reference.

For now, laptop cameras are mostly computer-built cameras that add to the USB external. For the computer built-in camera is mainly notebook and part of the LCD display mainly built-in, built-in camera general problems are relatively few, mainly pay attention to the driver problem, we encounter the most cameras are not available should be a USB external camera bar.

If your computer with a USB camera is not available, first of all we need to check the camera USB cable is connected with the host (recommended to connect the host after the USB interface, because the author found that some computer host USB interface is not available, such as the discovery of USB access to the host front USB interface is unavailable, Should try to plug in the back to try).

Novice Help:

After checking the line connection, we entered My Computer Device Manager to see if the computer detected a USB video device. Here is a screenshot of the camera that has been identified by the computer in Device Manager:

USB camera device in device management

The above is a successful USB camera installation, and all the normal situation, if you also see similar results, the camera and computer connection is normal, and computer recognition, drive has been installed successfully. If the camera is not available at this time most of the computer system software Setup problem, you can access the camera instructions. Another is that the computer found unknown devices, that is, the camera driver is not properly installed, the following figure:

The camera does not install or drive abnormal results

This behavior may have two reasons, one is that your camera driver is not installed correctly, the other is your USB interface has a hardware failure. Windows Xp/vista,windows 7 's operating system already has a majority of camera drivers built into it, but as product technology advances, some newer cameras may have to reinstall their own drivers to work properly. Therefore, it is recommended that you first install the camera you purchased the driver in the package, see if you can solve the problem, but also download a driver wizard, automatic detection of driver installation.

If there is no problem with the driver, the USB interface may be faulty. First you switch the camera to a USB slot connection, see if the normal use, if the other slot can be used to indicate that your original USB slot problem, if not, if not, change a computer to try again, still not good may be your camera has problems, recommend to repair or replacement.
