How it's used
While the full term is standard, many locals simply refer to these as 天眼, which literally translates to 'sky eye'. This nickname is widely understood and carries a slightly more informal, sometimes ominous tone when discussing privacy or security. Using the full term is safer in formal or professional contexts, such as when reporting an incident to the police or building management.
