Systems and methods for notifying particular devices based on estimated distance

This disclosure relates to notification systems and methods for providing a notification of detected prohibited behavior to a user device that is estimated to be nearest to a particular location. In aspects of the present disclosure, a notification system includes at least one sensor configured to sense measurements indicative of a prohibited behavior, a wireless device passive monitor, a processor, and a memory having stored thereon instructions. The instructions, when executed by the processor, cause the notification system to detect an occurrence of the prohibited behavior based on the sensed measurements, estimate which user device from a predetermined list of user devices is a nearest user device to the wireless device passive monitor, and provide a notification to the estimated nearest user device regarding the detected occurrence of the prohibited behavior.
