Abstract: A system for detecting human entry into a container using electromagnetic imaging to generate image maps of the container. The system includes a door monitor configured to detect an entry door open event associated with the container. The system uses one or more processors and a memory with instructions to generate a baseline image map of the container, detect an entry door open event with the door monitor associated with the container, generate a post entry door open event image map of the container, and compare the baseline image map generated before the entry door open event with image map generated after the entry door open event.
