First of all, almost any facial surveillance system would simply reject images like those from Lord & Taylor's. The pixel density is simply too low to even attempt plus the downtilt would also likely trigger a rejection. That's how facial recognition does work in practice. Even if the system would allow it, not only would false positives be enormous, you'd probably miss the match as well (false negative).
