Detecting Being Watched
This seems like science fiction to me:
The camera uses the same "red eye" effect of from camera flashes to project it hundreds of meters, allowing it to identify binoculars, sniper scopes, cameras and even human eyeballs that are staring at you....

Been done for years as anti-sniper technology - you just look for retro-reflections from the scope. There are even anti-anti-sniper countermeasures, a beehive hood = a set of hexagonal tubes on the front of the scope to limit the angle you can see the lens from.
False positives are less of a problem, there aren't many optical elements pointing at you from a forest on a battle field.
Not going to work a damn on the street though!
