I don't know anything about facial recognition software so I'm probably underestimating the difficulty of alerting the system and it's operators to the interesting possibility of giraffes and zebras wandering around the urban environment.

Facial recognition tech is basically two parts: detecting a face in an image (“face detection”, often this is done by calling out to OpenCV’s face detection in Python or C++), and then extracting information from that face image and searching a database with it (“facial recognition”, sometimes done with algorithmic measurement of facial features but increasingly done by neural networks).

This clothing looks like it might be designed to confuse the face detection step.
