A system and method for tracking moving objects

A system comprising:

• a sensor unit that includes movable sensor, the sensor unit is configured to generate a succession of images of a scene, a remote control unit configured to communicate with the sensor unit through a communication link and receive through the link at least said succession of images, and transmit through said link object data that pertain to an object that is embedded in images of the scene, in response to selection of the object in an image;
• the system is configured to accomplish substantially realtime location of the object notwithstanding a time delay constituted by a timing difference between a first timing that an image including the object is generated in said sensor and a second timing in which said object is located in realtime image;
• wherein the sensor unit is configured to
• receive data indicative of estimated future coarse location of an object in the scene;
• generate a succession of images of an area in the scene, the images includes the estimated coarse location;
• compare between at least two images of said succession;
• and in case of a difference in at least a respective portion of the at least two images meets a given threshold, identify the difference, in a later image, as a candidate object of said object.
