Systems and methods for tracking objects

An apparatus in a video surveillance system for tracking an of-interest (OI) object, comprising:

• a memory;
• and
• a processor coupled with the memory and configured to:
• receive, from a user interface, a request to track an object in a first video stream from a plurality of video streams captured from a first camera of a plurality of cameras installed in an environment;
• extract at least one image of the object from the first video stream;
• generate a unique biometric identifier of the object based on the at least one image;
• monitor the plurality of video streams for the object by comparing a candidate unique biometric identifier of a candidate object in at least one of the plurality of video streams with the unique biometric identifier of the object;
• detect, based on the monitoring, the object in a second video stream captured from a second camera of the plurality of cameras;
• and
• output, on the user interface, the second video stream in response to detect the object in the second video stream.
