With the ability to take photos, record videos, video call with family, friends, Live Stream on Facebook, Youtube… Extremely flexible, the camera is also a weak point on the computer that hackers always target.
In recent years, there have been many cases of theft of photos and personal information due to webcam hacking without knowing it, causing these images to spread all over the Internet, very dangerous.

Previously Webcam was really not used much !
But since Microsoft launched the Windows Hello feature – a feature similar to Apple’s FaceID system, allowing you to use your face to unlock your computer, people have paid more attention to laptops / monitors. picture with high quality webcam.
It is also impossible not to mention the impact of the Covid 19 pandemic, when people study online and families meet online, the camera is even more important.
You also can’t know you’re being secretly filmed because by default, Windows will not display a message about whether the webcam is being used by any component on the system.
Some laptops are equipped with light signals on the left / right side of the body or right next to the webcam and they will light or blink (depending on the device) when the camera is active.
However, this method does not seem to be very effective because when you are engrossed, focused on playing games, watching movies, etc., if someone comes near you, you don’t even know what to say to that small signal ^^
Meanwhile, with just a few small tweaks in the Windows Registry, we can easily display a message on the screen when our webcam is turned on or off.
For example, when you click to answer a video call on Messenger, a notification will immediately appear, and when the call ends, you will also receive a notification. Camera Off similar.

If you don’t have this key either, just create a new key with the same name by right-clicking in the right box (anywhere) => then select
New=>DWORD (32-bit) Valuedone. If you already have one like me, go to the next step.
Now right click on the key NoPhysicalCameraLED => then choose Modify… or faster double-click on its name to open the window to edit the values of the keys in the Registry.
Then a window Edit DWORD (32-bit) Value appears and please edit the value in the box Value Data are from 0 Fort 1all the rest stay the same and then press the . button OK to save.

Windows will immediately notify Camera On as shown below and when the Webcam is no longer in use, you will also receive a notification Camera Off on the screen.
But it must also be noted that, not all applications that use Webcam are detected and displayed using status messages by Windows, so this is not the most perfect way, you should still be careful. Can cover the camera when not in use!
