There are anonymous data that are interesting for advertising. The number of people passing by a location is anonymous in itself.
It seems however that in the case of the Canadian mall implementation (or more precisely their solution provider) they stored more than this number, losing the anonymous property of a system they sold as an "Anonymous Video Analytics".
In my opinion, something should be called anonymous if and only if you cannot go back from the stored data to a personally identifiable information.
