Researchers at Purdue University have found a new way to get surveillance cameras to “talk” to the people they see. The system is called PHADE, which stands for “private human addressing”, and it enables cameras to send messages to people’s devices when they have entered a specific area without collecting their personal data. Like many aspects of retail surveillance, police departments would undoubtedly be interested in the technology as well.
