For the current system installed in Shenzhen, Intellifusion installed
cameras with 7 million pixels of resolution to
capture photos of pedestrians crossing the road against

And, of course, that Google Glass is (for now) arguably as plain as the nose on the face of the wearer while — notionally out of site (added — oops: I meant «sight», but the pun almost works) so out of mind — it's easy to forget the likelihood that the same scene is being
captured by the
traffic surveillance
cameras, the outward - looking surveillance
cameras on the buildings in the area, perhaps the ATM
camera behind one, and the
cameras & video recorders on the smartphones or tablets that the nearby tourists used to take pictures.
