Tracking Multiple person with multi-Camera

I have a project that is for tracking multiple people using single camera. I want to extend it for multiple camera with assigning unique id for person in same location for different orientation because i want to use Multiple Camera. we want that at least two window open for same video in different location(our input video) and person should be tracked in those videos with same ids(example for person 1 id 1 in video1 and id 1 in different video for same person)
