With modern wide angle lenses, it doesn't even need to be pointed directly at you to get you completely in the frame.

I don't know. Its weird. Kind of like how people have the "someone's staring at you" sense. > The biological phenomenon is known as “gaze detection” or “gaze perception.” Neurological studies have found that the brain cells that initiate this response are very precise. If someone turns their gaze off of you by turning just a few degrees to their left or right, that eerie feeling quickly fades. I 100% beleive we also do this with smartphones. You can 100% detect when a smartphone is looking at you or just being held in your direction. It might not be proven scientifically yet but I know this in my soul. Similar to our ability to determine what someone else is looking at. We can watch someone's purpils move, and then immediately look at the exact area they looked at.

  Also, gaze detection extends beyond humans [1]. Citation mentions dogs, birds, and reptiles having some degree of it. In general, attention detection via gaze or body language would be an evolutionary advantage for any prey animal, and even a predator that is low in the overall food chain. Anecdotally, I’ve seen similar behavior in spiders, though the literature [2] tells me it’s not specifically gaze that a spider is detecting. I have hunted (to trap) spiders around my house who seem to change behavior (eg play dead) based on my attention, leading me to think that they know they are being hunted on some level well below cognition. Which, coming full circle, lines up with the literature on how crazy accurate human gaze detection is, seems like a very old, low-level function.
