Hi Dear!
From what I understood SkyEye doesn't recognize one's stride specifically, but this is how I think it works (note that these are not faces but more my interpretations based on what i saw):
- you pin the focus on one car/being etc, when you see it on the security film. Whether you look at the live security or old tapes, the system will keep switching to camera's that show the thing/person you pinned the focus on so you can follow where it goes.
For whether this is real, i did some digging and did find one similiar thing:

A quote from the site:
Our video backhauling options allow for simple and limitless expansion of any security surveillance system, and our video management software is free and can be integrated with any existing main-stream VMS.
However, I haven't searched on the chinese web nor can I read chinese, so I don't know if something similiar exists there (would be some pretty neat product placement).
