For residents who want to find out whether Flock cameras are operating in their area, and on what terms, the Atlas of Surveillance offers the most comprehensive public resource available. The site has become a go‑to source for mapping police technology — which also includes drones, facial-recognition cameras and body cameras — with a searchable database that’s often more dependable than alternatives. Self-reports are also becoming less reliable as surveillance cameras are being hidden in speed signs and cacti. The Atlas database isn’t perfect, and the volunteers can do only so much. As I’ve covered before, some cities will carefully omit the name “Flock” when announcing new surveillance or monitoring programs, even if they are using the brand’s drones or ALPR cameras.
