Keep in mind that there is no approval process, no permit system, no application process, no review and no control over the installation of this type of video surviellance equipment in Nova Scotia.
Anyone can install a camera in any public place and do what they want, be that viewing, recording video, using face recognition software, selling data and images, tracking the movement of private individuals or whatever else they can get away with.
Since the Halifax Police Service is keenly interested in using CCTV to monitor public streets it seems unlikley they would raise any objections related to privacy issues.
