If you ever were concerned that your every move was being watched by somebody, well, in NYC, it just might be. In this video from AP, ¬†we see a live demo of just how efficient and scary NYPD’s Domain Awareness System is. Within a matter of seconds of an emergency call, the system triggers feeds from all surrounding security cameras 30-seconds before the call came in, giving police an overview of what the situation that just unfolded looked like seconds before it became a situation.
