Image data describing a physical space is received from one or more sensor(s). A corresponding image of the physical space is output to a user. User generated control signals are received, indicating to define one or more line(s) at specific coordinates in relation to the physical space. One or more line(s) are defined in response to the received control signals. Polarity is assigned to the line(s), wherein crossing a line in a first direction is defined as an ingress and crossing a line in a second, opposite direction is defined as an egress. An image of the line(s) is superimposed on the image of the physical space, wherein the image of the line(s) graphically indicates the assigned polarity. Physical objects are monitored in relation to the one or more line(s) in the physical space. An action is automatically taken in response to activity detected by the monitoring.
