Web Camera F 20 F4 8mm8 Driver [work]

Here’s what you can do to find the correct driver:

1. Check the Device Itself
   Look for a sticker on the camera cable or body for a proper model number (e.g., "F20" might be a generic chipset label). Common webcam chipsets are from Sonix, Generalplus, or Ali.

2. Use the Hardware ID

   • Open Device Manager → find the unknown device (likely under "Imaging devices" or with a yellow exclamation mark).
   • Right-click → Properties → Details → Hardware Ids from the dropdown.
   • Search online for the VID/PID code (e.g., VID_0C45&PID_6340).

3. Try Generic Drivers
   Many generic webcams use Microsoft’s built-in USB Video Class (UVC) driver. Uninstall any failed driver, unplug the camera, restart Windows, then plug it in again—it should auto-install.

4. Alternative Names
   Could the camera be something like A4Tech F-20 or F20 USB 8mm lens? If it's an endoscope or microscope camera, the driver might come from a CD or a site like "ali_webcam_driver.com" (though be cautious with such sources).

If you can provide the VID/PID (e.g., from Device Manager), I can help identify the exact chipset and link you to the correct driver source. web camera f 20 f4 8mm8 driver

Here’s a forum-style support post based on your topic. I’ve interpreted “f 20 f4 8mm8” as likely a typo or specific model variant (e.g., “F/20 F/4 8mm” lens marking or “F20” chipset).

Title: Need driver for webcam – markings: F 20 F4 8mm8 – not auto-detecting

Post:

Hi everyone,

I have an older USB webcam with no brand name on the casing. The only markings are on the lens barrel / sticker: Here’s what you can do to find the correct driver:

F 20
F4
8mm8

Windows 10/11 detects it as a “USB Video Device” but the image is black/green/garbage. I suspect a missing or corrupted driver.

What I’ve tried:

• Plugging into USB 2.0 and 3.0 ports
• Updating driver via Device Manager (says best driver already installed)
• Trying generic UVC drivers (no change)
• Looking for any INF file on the web using F20 F4 8mm8 – no luck

My guess:

• F 20 could be the model or chip revision (maybe a Sonix or Prolix chip?)
• F4 – aperture marking (unlikely for a driver, but part of the lens label)
• 8mm8 – possibly a fixed focus 8mm lens marking

Has anyone seen this camera before? Or can you recommend a way to extract the USB VID/PID to find a compatible driver?

Thanks in advance.

Reply from another user (if you want to include a solution):

Check the VID/PID in Device Manager → Properties → Details → Hardware Ids.
Then search VID_xxxx&PID_yyyy on [driver database site].
Many no-name cams with “F20” use the Sonix SN9C120 or M1330 chipset. Try the driver from the sonix_sn9c120.zip package.
