under the new system, a network of dozens of video cameras feeds a constant flow of digital data to security.
When a parent reports a missing child, the system can—within a few minutes—locate the video of when the parent and the child were last together and then show footage of exactly where the child went and with whom, even showing where the child is at that moment, assuming the child has not left the store. If the child had left, it would show when and could even track the child to the parking lot, possibly capturing a license plate and footage of a car.
