preparation
Firstly, you need to prepare a camera that meets your needs. Generally speaking, cameras are connected to a computer through a USB interface, so you need to purchase a USB camera that meets your needs and ensure that the purchased USB camera is compatible with the computer. Usually, most USB cameras on the market are compatible with the Windows 10 system.

This USB 2-megapixel high-definition mid screen network camera is very easy to install and use, making it the best choice for video conferencing cameras!

Installation steps
Connect the camera
Insert the USB data cable of the camera into the computer interface. Generally, the USB interface of the computer is located in the USB expansion slot on the front panel or back of the chassis. If the camera has other additional interfaces, such as audio or power interfaces, please also connect them to the corresponding sockets on the computer.
Automatically install drivers (in most cases)
Generally speaking, the Windows 10 system can automatically install drivers for most cameras. After inserting the camera, there will be a notification prompt in the lower right corner to automatically install the camera. At this point, wait for the system to automatically complete the driver installation.
Test camera
Click on the "Start" icon in the bottom left corner, select the "Camera" option from the pop-up menu bar or third-party software installed on the computer, and then check if the screen is working properly. If you can see the footage captured by the camera, it means that the camera has been successfully installed and can be used normally.
By following the above simple steps, you can successfully install the camera on a Win10 system computer and enjoy the convenient functions brought by the camera.

Basic installation steps (applicable to most situations)
1. Connect the camera: Insert the USB camera cable into the available USB port on the computer.
If the camera has a separate power cord (not commonly found in regular USB cameras), please also connect it to power.
Important notice: It is recommended to directly plug into the USB port on the computer motherboard (behind the chassis), rather than through a USB hub or front panel port. The front-end ports or hubs sometimes have insufficient power supply or unstable signals.
2. Wait for the system to automatically recognize and install:
After Windows 10 detects a new USB device, a notification will pop up in the system tray area in the bottom right corner: "Setting up device" or "Device ready".
The system will automatically search and install the most compatible universal driver in the background. This process usually only takes a few seconds to tens of seconds.
3. Verify if the camera is working properly:
Using the built-in camera app:
Click the start button.
Enter 'camera' and open the 'camera' application.
If the camera is working properly, you should be able to see real-time footage. The application may request access to the camera, please click 'Yes'.
Use other video software: Open your commonly used video calling software (such as Zoom, Microsoft Teams, Skype, WeChat, QQ, etc.) or live streaming software (such as OBS Studio). Go to the software settings or video device options, select your USB camera, and you should be able to see the screen.

If the camera still cannot be used after completing the above steps, please try the following methods:
1. Check physical connections and ports:
Try inserting the camera into another USB port (preferably the USB 2.0 or 3.0 port on the motherboard behind the chassis).
If a USB extension cable or hub is used, please remove them and directly connect the camera to the computer's USB port.
Try connecting the camera to another computer and confirm if the camera itself is intact.
2. Check the device manager:
Right click on the start button and select Device Manager.
Expand the category of cameras or imaging devices. Your USB camera should be listed here.
If the camera can be seen without warning signs: it indicates that the driver has been installed, and the problem may be in other areas (such as privacy settings, software settings).
If you see a yellow exclamation mark next to the camera ⚠  Or a question mark? : Indicates that there is a problem or incorrect installation of the driver.
If you see an entry with an exclamation mark under other devices or unknown devices (the name may be "USB device", "camera", or vague description): This usually indicates that the driver is not installed or has failed to install.
If no new entries related to the camera can be found at all: it may be a hardware connection issue (cable, port, camera failure) or a very serious driver problem.

3. Update or reinstall drivers (when there is a problem flag in Device Manager):

In Device Manager, right-click on the problematic camera device. (Update the driver provided by the manufacturer)
4. Check Windows privacy settings (camera access permissions): Windows 10 strictly controls application access to cameras. Even if the driver is installed, if the permission is not enabled, the application cannot see the image.
Open Settings>Privacy>Camera.
Ensure that the switch allowing applications to access your camera is turned on.
Scroll down to the Microsoft Store app section where you can access your camera, and make sure the switch next to the app you are using (such as the Camera app, Zoom, browser, etc.) is also turned on.
For desktop applications (non Microsoft Store applications such as OBS and many third-party chat apps), permissions are usually controlled by the system (i.e. the top main switch), but please also check if there is a camera permission option in the settings of the relevant software itself.

5. Select the correct camera in the application: Open the application where you want to use the camera (such as Zoom, Teams, OBS, etc.).
Go to the settings or preferences menu of the application and find the "Video" or "Camera" settings options.
In the device list, make sure to select the USB camera you are connecting to (usually named by brand or model), rather than "disabled" or selecting another device (such as a virtual camera that comes with an integrated graphics card or another connected camera).
6. Troubleshooting hardware and devices: Open Settings>Update and Security>Troubleshooting.
Select Hardware and Devices>Run Troubleshooting.
Follow the guide to see if you can detect and fix camera related issues.

summarize
For the vast majority of USB cameras, on Windows 10, simply plug in the USB port ->wait for automatic installation to complete ->open the "Camera" application for testing in three steps. If encountering problems, the core troubleshooting points are:
1. Device Manager: Check device status and driver status (exclamation mark/question mark).
2. Privacy settings: Ensure that both the system and applications have access to the camera.
3. Application settings: Ensure that the correct camera device is selected.
4. Official driver: When the automatic driver is ineffective, manually installing the official website driver is usually the best solution.
By following these steps, your USB camera should be able to work properly on Windows 10.
