The camera is always on. That’s how you’re able to see the photo you’re about to take on screen. 

Film cameras didn’t have displays that showed what you’d capture, they had a little viewfinder you’d close one eye to look through like a telescope. That’s why old people hold their hands up to their face when they do a “take photo” gesture.
