Before you begin

Before working through the possible solutions listed, do these first:

• Check for updates. Select Start , then select Settings > Update & Security > Windows Update > Check for updates. If you see the option to View optional updates, select it to see if there are updates available for your camera. Allow available updates to install, then restart your device when it's ready.

• Restart your PC. If you haven't restarted your device since the camera stopped working, you should do so. Select Start , then select Power > Restart. Waking up your device from sleep isn't the same thing as a restart.

• Test your camera with the Camera app. Select Start , then choose Camera from the list of apps. If you're asked to allow access to the Camera, select Yes. If the camera works in the Camera app, the problem might be with the app you're trying to use.
  Open Camera

If your camera still doesn’t work, here are some other things to try. For best results, try the possible fixes in the order presented.

Check for a camera switch or button your device

Some laptops and portable devices have a physical switch or button that turns the camera on or off. When turned off, your device won't recognize that there's a camera installed. If your computer has a switch or button, make sure it's in the on position before using your camera.

Check your settings

Give your apps permission

If you recently updated Windows 10, you might need to give apps permission to use the camera. In newer versions of Windows 10, some apps don’t have default access to the camera.

To let your device access the camera, select Start , then select Settings > Privacy > Camera . In Allow access to the camera on this device, if Camera access for this device is turned off, select Change and turn on Camera access for this device.

Note: If camera access for the device is turned off and you can't select Change, you'll need an administrator on the device to turn on camera access for you.

Before any app can access your camera, make sure camera access is turned on for apps in your user account. Make sure that Allow apps to access your camera is turned on.

After allowing access to the camera, go to Choose which Microsoft Store apps can access your camera and turn on camera access for the apps you want. Only apps installed from the Microsoft Store will show in this list.

If you installed the app from the internet, a disc, a USB drive, or your IT administrator installed the app for you, it might not be a Microsoft Store app. To check, go to Allow desktop apps access to your camera and make sure it's turned on. Many video conferencing apps, like Microsoft Teams, are desktop apps that require this setting to be turned on.

Check your antivirus software

In your antivirus software settings, look for settings that block access to your camera or permission to use your camera. For help, visit your antivirus software company’s website.

Check your hardware drivers

Try a different USB port and scan for hardware changes

If you're using an external camera, try using it with a different USB port on your device first. If that doesn't work, or your camera is built-in to your device, try this:

1. Select Start , enter device manager, then select it from the search results.

2. Find your camera under Cameras, Imaging devices or Sound, video and game controllers.

3. If you can't find your camera, select the Action menu, then select Scan for hardware changes.

4. Wait for it to scan and reinstall updated drivers, restart your device, then try opening the Camera app again.

5. If these steps don't fix your issue, continue to the next steps.

Check for an incompatible camera driver

Some older cameras that were designed for older devices aren't compatible with Windows 10. Here's how to check if you have if your camera is compatible:

1. In Device Manager, look for your camera under Cameras, Imaging devices or Sound, video and game controllers.

2. Press and hold (or right-click) the name of your camera, and then select Properties.

3. Select the Driver tab, select the Driver Details button, and look for a file name that includes stream.sys. If it’s there, your camera was designed before Windows 7 and you'll have to replace it with a newer camera.

4. If you don't find a file name that includes stream.sys, continue to the next steps.

Roll back the camera driver

If your camera stopped working after an update, try these steps:

1. In Device Manager, press and hold (or right-click) your camera, and then select Properties.

2. Select the Driver tab, select Roll Back Driver, and then choose Yes. (Some drivers don’t provide this option. If your driver doesn’t have Roll Back Driver available, go ahead to the next fix.)

3. After the roll back is complete, restart your device, and then try opening the Camera app again.

4. If rolling back didn’t work or isn’t available, continue to the next steps.

Uninstall your camera driver and scan for hardware changes

1. In Device Manager, press and hold (or right-click) your camera, and then select Properties.

2. Select the Driver tab, then select Uninstall Device. Select the check box for Deletethe driver software for this device, then select OK.

3. In Device Manager, on the Action menu, select Scan for hardware changes.

4. Wait for it to scan and reinstall updated drivers, restart your PC, and then try opening the Camera app again.

Note: If your camera still doesn’t work, look for help on the camera manufacturer’s website.

Teardown

Thiscamera is probably the cheapest on on the market ever. It could be purchased for less than $3 ongoodsmall999 Ebay shop:Mini Stylish USB 2.0 5M Meter Retractable Clip WebCam Web Camera Laptop PC G9.

The seller declares it as a 5M HD camera, but probably nobody wouldeven believe it. Lens frame lies even more, and declares that it is an8.0 Megapixel camera.

I was interested how well it performs and what is inside.

Board

Lens

You can see that the IR block filter is part of lenses. I did not tryto remove it yet, but it seems to be the topmost element.

USB identification

Camera is an UVC standard camera and supports up to 640×480 at 30 fps.So it is 0.3MPix in the fact.

The camera can produce YUV output only. (Itis not a problem for the most of the recent software.)

Supported resolutions: 640×480, 352×288 (seems to have stability problems), 320×240, 176×144, 160×120

Supported FPS: 30fps, 15fps

Supported controls: brightness, contrast, saturation, hue, power line frequency, gamma sharpness, backlight compensation

It reports itself not only as a camera, but also asan input device. It means that the chip probably supports button.

Analysis

The camera has a very low field of view (horizontal field of viewis approximately 24°), but the image is a pretty sharp and colors aregood.

Lens holder is pretty large and has a long thread. If itis unscrewed as much as possible, it can be turned to a cheap microscope.But you need to remove the cover for this purpose, as it makes impossibleto unscrew so much.

The camera has no microphone (and also no hole in the case you can seeon the listing photos).

The whole board consists from a single IC, CMOS sensor itself and afew parts. There is apparently a space for LED light and one IC (USBid memory?).

If you use the camera without the case, protect it fromstrong sidelight. It can cause reflections of PCB traces directly to thesensor.

Board revision: AX2311-BC-0309-6DBY-001

CMOS sensor

TheCMOS sensor is aGalaxycore GC0309640x480@30fps 1/9″ sensor with pixel array size 648×488 pixels(datasheet).

It has a very good sensitivity in the infrared range, so it couldbe used for infrared experiments.

USB controller

The USB controller is labeled with anAppoTech logo andletters: 2311-A4F EAPR28193_1 1412ARZ. Guessing from the PCB print, it isan AppoTech AX2311. But it does not help at all. There isno single reference to such part anywhere on the net.

Examples

Indoor

Standard conditions

Low light

Web camera

(If the video does not play to you, download video here.)

Used as microscope

This example was made with camera open, microscope slide lying on topof the lens frame. The limiting factor was the height of theframe, not the thread length.

Long term experience

It is not suitable for 24/7 use. The firmware is a bit flaky, andfreezes about once a week. You need to unplug and plug again to get itworking again.

Summary

If you expect a decent 640×480, it is definitely a good deal.

Pros

Usb Pc Camera Driver

• Cheap
• Small
• Decent image quality
• Low FOV (well, it is good only for somebody)
• Can be probably transformed to IR camera
• Lens are deep behind the lens frame edge, which protects them fromscratches and accidental touching.
• Auto white balance performs indoor well.

Cons

• 640×480 pixels is a basic resolution
• 30 fps is not so much
• Low FOV (well, it is bad only for somebody)
• Lens are deep behind the lens frame edge, which causes problems whentrying to attach to an eyepiece of a microscope or telescope.
• Exposition automatics avarages the whole frame in a non-optimal way.If the image from microscope or telescope covers only the image center,it is overexposed.
• Exposition automatic could be a bit faster.
• Unstable firmware.
