A method of an image sensor circuit includes: providing an event camera comprising at least one pixel unit; using the event camera to sense at least one current pixel value of the at least one pixel unit to detect whether at least one pixel value changes; when the at least one pixel value changes, using the event camera to trigger the digital processing circuit when the digital processing circuit is in a power saving mode and transmit information of the at least one pixel value to the digital processing circuit.

A system includes a plurality of sensors distributed about a space. Each sensor generates sensor data associated with properties of one or more people in the space. An automated response subsystem receives the sensor data. An unauthorized activity performed by a first person in the space is detected based on at least a portion of the received sensor data. In response to detecting the unauthorized activity, tracking instructions are transmitted that identify the first person associated with the unauthorized activity. A tracking device receives the tracking instructions. A device associated with the first person is detected. Over a period of time, the tracking device sends queries to the device and receives corresponding responses from the device. The tracking device determines positions of the device within the space over the period of time.

Disclosed is a monitoring system, having: a keybox configured to store a key; a monitoring device, wherein via a monitoring device controller, the monitoring device is configured to: detect a first alert condition indicative of the keybox being outside a communication range of shortwave radio; and transmit a first alert to a remote implement that is indicative of an occurrence of the first alert condition.
