1. A system comprising:

  • a first camera configured to acquire a plurality of first image frames of at least a first scene and output first image data; and

    a controller configured to communicate with the first camera and configured to;

    receive first period data, wherein the first period data is first image data associated with a first time period,process the first period data to generate processed first period data of binary images,analyze the processed first period data to determine a presence of an object of interest within at least one image frame of the processed first period data and highlight the object of interest within the at least one image frame of the processed first period data,analyze movement of the highlighted object of interest within the at least one image frame of the processed first period data to determine a historical movement pattern of the object within the first scene,store the historical movement pattern,receive, after the storing the historical movement pattern, second period data, wherein the second period data is first image data associated with a second time period,process the second period data to generate processed second period data of binary images,analyze the processed second period data to determine a presence of the object of interest within at least one image frame of the processed second period data and highlight the object of interest within the at least one image frame of the processed second period data,analyze movement of the highlighted object of interest within the at least one image frame of the processed second period data to determine a recent movement pattern of the object,compare the recent movement pattern of the object to the stored historical movement pattern of the object,determine, responsive to the comparison, that an anomalous trigger condition has been met, andoutput an alarm or response message in response to determining that the anomalous trigger condition has been met.
