How to Update a Webcam Firmware: Steps and What It Fixes

What webcam firmware is and why it matters

A webcam is a small computer. It has an image sensor, a lens, and a processor that turns sensor data into the video frames your apps receive, and the software that runs on that processor is called firmware. Firmware controls auto exposure, autofocus, white balance, noise reduction, HDR processing, and the way the camera talks to the computer over USB.

Firmware is not the same as a driver. Most webcams follow the USB Video Class (UVC) standard, and Windows provides a built-in UVC driver that queries the camera directly, so no proprietary driver needs to be installed. Updating firmware is a separate job: you replace the maker's software stored inside the camera, not a driver in the operating system. See how UVC webcams work and what drivers do for the difference.

Why makers release firmware updates

Firmware updates exist for the same reasons other software gets updated: to fix bugs and to improve behavior. A camera's processor handles tasks such as noise reduction, exposure weighting, autofocus control, and HDR merging, and a new firmware version can correct errors in those routines or make them react better in difficult lighting.

Updates can also add or tune features. Some webcams gain better autofocus tracking, improved HDR, or new AI framing through a firmware change, and because many cameras store exposure, white balance, and focus preferences on the camera itself, the update keeps working with the settings you saved.

Certification programs are another reason. Conferencing platforms run certification programs that set performance targets across audio, video, and user interface, and makers adjust firmware so that certified cameras continue to meet those requirements. Read more about what firmware updates fix.

Finding your current firmware version

Before updating, you need to know which firmware version your camera is running. Most makers list the current version and release notes on their official support page, and many also show it in their companion app. For example, the Elgato Camera Hub app displays firmware information and allows you to update the camera. Similarly, Razer Synapse and the OBSBOT app provide access to device settings and firmware updates.

If you cannot find the version in the app, check the maker's product page or support downloads section. The version is typically a number like "1.2.3" or a date string. Write it down so you can compare after the update. Also note any custom settings you have stored on the camera, such as white balance, exposure, or focus positions, because some updates may reset them. If you are unsure where to look, check your firmware version for step-by-step instructions.

How to update your webcam firmware

Updating firmware is usually a straightforward process, but you should follow the maker's specific instructions. The general steps are:

First, close any applications that are using the camera, such as video conferencing, streaming, or recording software. This prevents the update utility from being blocked by an open handle.

Next, connect the webcam directly to your computer using the included cable. Avoid using a hub or a long extension if possible, because a stable connection is important. Some cameras need to be plugged into a USB 3.0 port, as with the Elgato Facecam Pro, which uses USB 3.0 for uncompressed 4K60 video.

Then, download the firmware update file from the maker's official support page or through their companion app. Run the updater as administrator if required. The updater will detect the camera and transfer the new firmware to its internal memory.

During the update, keep the camera connected and do not unplug it or cut power. The camera's LED may blink or turn off while the update is in progress. After it finishes, the updater will usually confirm the new version and ask you to reconnect or restart the camera.

Some systems, such as Windows, may need to refresh the device. You can unplug the camera and plug it back in, or use Device Manager to scan for hardware changes. If the update fails, check the maker's troubleshooting guide and make sure you have the correct version for your model.

• Close all apps that access the camera.
• Connect the camera directly to a USB port, ideally with the supplied cable.
• Download the firmware file from the maker's official support page or companion app.
• Run the updater with administrative rights if needed and follow the on-screen instructions.
• Wait until the update completes, then reconnect the camera or restart the computer.
• Verify the new version and restore your saved settings.

After the update: verify and adjust

Once the update finishes, check the firmware version again to confirm it matches the latest release. Open your companion app or the maker's support page to verify. Then test the camera in a video call or recording app to ensure everything works normally.

Some firmware updates reset the camera to factory defaults. If that happens, you will need to re-apply any custom exposure, white balance, or focus settings. Many cameras have on-board memory, so you can save your preferences after adjusting them again.

If you use the camera with a platform that has certification requirements, such as Microsoft Teams Rooms, the update should maintain or improve compatibility. The Microsoft Teams Devices Certification Program sets high performance targets, and firmware updates help cameras meet those standards over time.

If you encounter problems after an update, first try a different USB port or cable. Check the camera's privacy settings in Windows to make sure apps still have permission to access it. You can manage camera access in Settings > Privacy & security > Camera, as described by Microsoft. If the issue persists, contact the maker's support for a rollback option, though not all makers provide it.

What to pick for your use

Questions

How do I know if my webcam needs a firmware update?

Check the maker's support page or companion app. If the version number there is higher than the one in your camera, an update is available. Release notes often indicate bug fixes or new features that may improve your webcam's behavior.

Do webcam firmware updates happen automatically?

Some companion apps can check for updates automatically, but you typically have to approve and install them manually. Managing updates through the maker's official software is safest, as it ensures you get the correct version for your model.

Can a firmware update break my webcam?

Any software update carries some risk, but following the maker's instructions and keeping the camera powered on during the process minimizes it. If the update fails, the camera may become unresponsive. In that case, try reconnecting it and running the updater again. Most makers design the process to be safe, but a rare glitch can occur.

Will updating firmware erase my camera settings?

Some updates reset the camera to factory defaults, so you may lose custom white balance, exposure, or focus settings. It is a good idea to note them down before updating. Many cameras also store settings in on-board memory, so you can re-apply them after the update.

Is updating firmware the same as updating the driver on Windows?

No. A driver is software in the operating system that communicates with the device. Most webcams use the USB Video Class driver built into Windows, which does not need to be downloaded separately. Firmware is the software inside the camera itself, and it is updated with a separate tool from the maker.
