This report examines the increasing deployment of landlord technologies in New York City (NYC) housing, and the problems this creates and intensifies. These technologies include facial recognition, closed-circuit television (CCTV) cameras, and other algorithmic, biometric, and appbased building access technologies specifically designed to be deployed in tenant housing and surrounding public and private space. We map the genealogies and geographies of these surveillance systems, looking at intersections of surveillance, carcerality, and gentrification.
