Comprehensive answers to the ten most frequently asked questions of network video cameras

With the boom of online video chat, the camera has become an inseparable tool for netizens. However, when you use it, you can still meet some common questions. Today, we have collected 10 more common questions and answered them.

  Q1 My computer cannot detect the camera?

A: Check whether the operating system, BIOS, USB interface and installation are correct.

Solution steps:

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

Step 2: Check the BIOS Setup to make the USB device effective.

If the settings are correct, the camera cannot be connected. Try connecting the camera to the second USB port.

If it is still invalid, 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 (take windows XP as an example):

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

Note: This is a relatively complicated problem and requires many attempts.

Q2 My camera has color deviation, what should I do?

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

Q3 My video preview image color is not correct, what should I do? That is to say, the color of the video preview image of the camera is not normal. Like the monitor that has been used for many years, the color starts to be abnormal, and it will be good after a while.

A: Please wait 20 ~ 30 seconds for Auto White to balance or correct. Note: For ordinary cameras, manual white adjustment is required. Before each shot, hold white paper and wait for the camera to adjust the white. The camera also has such a process.

Q4 My camera preview speed is too slow, what should I do? The camera I just bought, and I went online after installation, I feel that the display speed is very slow. I changed the ISP and changed a few Internet dialing locations, but the speed is still very slow.

A: Upgrade the computer hardware. Note: In view of the above situation, it is likely that the computer performance is too low, please replace the graphics accelerator card, if not, please upgrade the CPU and motherboard, or even replace a new computer. Because, after the update of individual accessories, performance performance is easily restricted by an old accessory.

Q5 I use a camera when surfing the Internet, but I find that the display speed of the camera is too slow, what should I do?

A: Change to a place to go online or change to an ISP. If you are currently surfing the Internet at home, such a problem occurs, you may wish to take the camera to another place (such as an office) to surf the Internet. If there is no such problem in the office, the internet speed in your home is too slow, please contact the network service provider. If you go online in the office, the speed is very slow, please refer to the previous Q4.

Q6 Is the quality of the video preview image of my camera too bright or too dark?

A: No, please adjust the brightness and contrast background. For details, please refer to the chapter about software settings in the manual. Note: You can also start from the use environment and ingesting objects, such as removing bright light sources or increasing the brightness of objects.

Q7 What should I do if the screen freezes when using the camera?

A: Check whether the camera driver matches the camera model. In addition, you can change the display card to test, because the camera may not be compatible with the graphics card or display driver.

Note: It is probably incompatible with 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 graphics card, it is easy to have such problems. If you cannot solve the problem by upgrading the driver of the graphics card, you can only replace the graphics card.

Q8 After installing the camera, the camera is installed. Since then I do n’t know which device I ’m using. I have to look at it from the camera or camera every time to know which device is “in service”. How can I set the default device?

A: The specific methods to make a video ingest driver effective are as follows:

Open the "Control Panel" and double-click the "Multimedia" icon. Select "Video", "Device".

Open the "Video Capture devices" (Video Capture devices) list, and double-click the PC-Camera name, which will open a dialog box that displays the properties of the camera.

Enable the driver as required. Because after you select a device, it is impossible to invalidate the remaining devices.

Note: When using multiple video ingest devices, the computer will use the default device. However, the default printing device cannot be set as easily as the printer device in Win9x, and there is no simpler way to determine the default device. Therefore, the best way is to choose one through a series of steps.

Q9 During use, what should I do if a white or black screen appears after the image frame pops up?

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

Q10 The camera that can be used normally on a brand desktop computer is not used normally after being connected to a laptop. Does it conflict with any device on the laptop? And there is no yellow symbol in "Device Manager", what should I do?

A: Please try to reduce the speed of the graphics card. Right-click on the desktop, select "Properties", "Settings", "Performance", gradually reduce the hardware acceleration from the fourth gear to the last gear to see if the problem can be solved. If you can, please gradually increase the grade until you find a balance that can solve the problem.

Note: The camera is most likely to conflict with the graphics card. After a problem occurs, in addition to finding the cause of the camera itself, in the peripherals, first check the graphics card.
