There are two types of webcams, depending on what computer you are using.
Option A
If you do not see the camera lens, the webcam is off.
Swivel the tab upwards and you'll see the camera lens (it has a red line around it).
Option B
If you see a red dot in the webcam lens, the webcam is switched off.
The switch is located above the lens. Move it to the right position to turn it on.
