Thank you for your footage!
All features are important, the intruder is the one who is the most overall different from the rest, the one that can be easily identified in a crowd. Behavior is also a thing, and should be analyzed for level > 5, but it's probably too hard, I didn't have enough time to improve it.
In fact, I tried to enumerate the features in the README (in the tips section I think), but I can't blame you, nobody reads the README haha.
