Google chrome has constant access to the webcam?

Question

Google Chrome

My computer is constantly on and I noticed such a thing. As soon as I approach him after a long absence, notifications of new mail immediately begin to pour in.
I use Checker Plus for gmail. It does not have access to the camera. Power saving and sleep modes are not included. Not even a splash screen. The monitor is working.
How the hell does he know I'm on my computer?

Answer 1

I pressed the key. The mouse moved.
