Traffic cameras are typically larger, mounted at intersections on signal arms, and face the road horizontally. Flock Safety cameras are smaller (roughly 8×5 inches), mounted on utility poles or fence posts at 8–12 ft, and often have a visible IR LED ring and a small solar panel. They are not connected to traffic signals.
Cameras can be operated by local police departments, HOAs, private businesses, or neighborhood associations. Flock Safety sells directly to all of these groups. The operator is not always disclosed publicly, which is why community mapping efforts like this one exist.
