Usb camera failure and how to solve

Why Q1 camera can not be detected by my computer after installation?

A: Solution steps:

Step 1: If your operating system is Windows 95, please upgrade to Windows 98 or later because Windows 95 does not support the USB interface.

Step 2: Check the BIOS Setup to enable the USB device.

If the settings are correct, or you cannot connect the camera, try connecting the camera to the second USB port.

If it still does not work, you may have installed the wrong driver or selected the wrong device. Please check the system device and install the correct driver again. The operation steps are as follows (using windows XP as an example):

In the "Control Panel" - "Administrative Tools" - "Computer Management" - "Device Manager", double-click "Other Devices" to view the content. Select Unknown Device and click the Remove button, then click Refresh. The system will find a new device and follow the installation steps to reinstall the camera driver.

Explanation: This is a more complicated issue and requires many attempts.

Q2: What's wrong with my camera?

A: Please refer to the software used by the camera to adjust the color-related settings in the video capture program.

Q3: What should I do if the color of my video preview image is not correct? That is to say, the color of the video preview image of the camera is not normal. Like the monitor used for many years, the color starts to be abnormal, and it can be a good time.

A: Please wait 20 to 30 seconds for Auto White to balance or correct. Note: For ordinary cameras, you need to manually adjust the white. Before each shot, you must hold a white paper and wait for the camera to turn white. The camera also has such a process.

Q4: My camera preview is too slow. What should I do? The camera that I just bought back was installed on the Internet. I felt that the display speed was very slow. I replaced the ISP and changed several Internet dialing sites. The result is still very slow.

A: Upgrade your computer hardware. Explanation: In view of the above situation, it is very likely that the performance of the computer is too low. Please replace the graphics accelerator card. If it is not enough, please upgrade the CPU and motherboard, or even replace a new one. Because, after the individual parts are updated, the performance is easily constrained by an old part.

Q5: When using the Internet, I used a camera, but I found that the camera's display speed is too slow. What should I do?

A: Go online or change an ISP for another place. If you are online at home and you have such a problem, you may wish to take the camera to a different place (such as an office) to go online. If you don't have this problem in your office, your home's internet speed is too slow. Please contact your Internet service provider. If you go online in the office, the speed is very slow. Please refer to Q4 above.

Q6: The video preview of my camera is too bright or too dark. Is it a quality problem?

A: No, please adjust the brightness and contrast background. For details, refer to the section on software settings in the manual. Note: It is also possible to start with the use of the environment and the ingested object, such as removing the bright light source or increasing the brightness of the object.

Q7: What should I do when using the camera?

A: Check if the camera driver matches the camera model. You can also change the video card test because the camera may not be compatible with the graphics card or display driver.

Description: It is most likely incompatible with the 6326 4MB AGP graphics card. Perhaps the driver is not installed correctly (it is recommended that you reinstall the driver). If you use the popular SiS 6326 chip video card, it is easy to have such a problem. If you cannot solve the problem by upgrading from the driver of the graphics card, you can only replace the graphics card.

Q8: After installing the camera, the camera is installed again. From then on, I don't know which device I'm using. I need to look at the camera or the camera every time before I know which device is in service. How can I set the default device?

A: The specific method to make a video intake driver valid is as follows:

Open the "Control Panel" and double-click on the "Multimedia" icon.

Select "Video", "Device".

Open the "Video Capture devices" list and double-click the name of the PC-Camera. This will open a dialog box showing the properties of the camera.

Make the driver valid as required. Because after you have selected a device, it is impossible to invalidate the rest of the device.

Note: When using multiple video ingest devices, the computer will use the default device. However, it is not as easy to set the default printing device as the printer device in Win9x. There is no simpler way to determine the default device. Therefore, the best method is to choose one through a series of steps.

Q9: Cameras that were normally used on branded desktop computers are not normally used after they are connected to laptops. Is it conflict with any device on the laptop? And there is no yellow symbol in the Device Manager. What should I do?

A: Try lowering the speed of the graphics card. Right-click on the desktop, select "Properties", "Settings", "Performance" and gradually reduce the hardware acceleration from the fourth file to the last file to see if it can solve the problem. If you can, raise your grade gradually until you find a balance that can solve the problem.

Explanation: The camera and the display card are the most likely to conflict. After a problem occurs, in addition to the reason for finding the camera itself, in the peripherals, the display card must be checked first.

Q10: What should I do if a white screen or a black screen appears after the image frame is displayed during use?

A: Please refer to the instructions in the manual to change the settings. It may be that "Preview" under the "Option" menu in the camera software is not open. Double-click and wait for five to ten seconds.
