We still have quite a bit to write about the end of Windows 10 support and the operating system change. In this case, we'll focus on using the webcam in Linux.
A webcam (short for the English words web camera) is a camera that captures photos or videos in real time and transmits them to a computer. In the case of notebooks, it comes integrated into the casing, while in desktop computers, it connects via a USB cable.
Yes, I know I'm saying things that are obvious to many, but experience has taught me not to assume everyone knows the basics, and this series of articles is for novice users.
Using the Webcam in Linux
Among the applications of webcams are:
- Video calls and video conferencing: In general, the most common services like Zoom, Google Meets, or Microsoft Teams can be used on Linux without any issues. In the first case, there's a native application; in the latter two, you can use them from a browser.
- Live Streams: The App Reigns in This Case es OBS Studio allows you to broadcast live using major streaming services, combining what your camera captures with content stored on your computer, your screen, and websites.
- Security and vigilance: MotionPlus You can record content from different cameras, both video and still images, and react to what the images show. The program can be accessed remotely, and the content can be stored in different databases.
- Photography and Video: There are several applications in the repositories that can be used to take photos or videos using the webcam. Some of them are: Kamoso which is intended for the KDE desktop and Cheese which is a similar tool but from the GNOME project.
An app that deserves a separate paragraph is Webcamoid. This program also takes photos and records videos, but with multiple cameras at the same time. It has customized controls for each camera. Although not the focus of this article, it also has a virtual camera function, allowing you to use a video file that the app will capture as a live capture.
Webcamoid offers effects like blur, animation, color filters, and pixelation. It also has add-ons that add functionality.
Webcam Safety Tips
Although a very useful tool, a webcam is a potential entry point for cyberattacks. For example, cybercriminals could remotely turn it on and use it to record conversations or spy on movements. The captured images and sounds could eventually be used for identity theft.
That's why it's helpful to take certain precautions. For example, if you use a desktop computer, unplug it when you're not using it. Other good practices include:
- Covering the webcam if it is integrated into the case: Specially designed covers are sold, although some type of opaque adhesive tape can also be used.
- Monitor the indicator lights. If they're on when you're not using them, something's wrong.
- Keep your software up to date, especially security-related software such as antivirus and firewall.
- Periodically review your security settings to see which apps have access to your camera and revoke it if they don't need it.
- Don't install applications from unknown sources. If possible, stick to official project repositories or websites.
- Use a secure password on your router when connecting via Wi-Fi.
- Disable the webcam from the operating system settings panel.
- Do not open suspicious emails or links from unknown sources.
As I've mentioned before, these are just a few applications that don't exhaust all the alternatives available in the Linux repositories. You can also use web applications like Microsoft's Clipchamp or Canva, which work perfectly. As for webcam compatibility, there are no reports of models that don't work with Linux so far. So, enjoy!
