What is the point of an IR camera on a laptop?
The primary purpose of having an IR camera on a laptop is security. Essentially an IR camera allows a similar level of security to prevent people who aren’t you from accessing your laptop as a fingerprint reader does, but by using face authentication.
Most commonly this is done via the Microsoft technology known as Windows Hello. Basically, rather than (or in addition to) entering a password to unlock your laptop, you can scan your face with the IR camera, which will recognize your unique features and let you in.
This can be accomplished because InfraRed light penetrates the surface layers of your skin, meaning it can pick out your unique facial features (such as surface vein patterns) that are harder to replicate. Basically, it gives more detail to your unique facial pattern compared to cameras which just detect the visible light spectrum, making it a more secure method of accessing your device.
