Closed-Circuit - English Definition & Meaning

Definition

Closed-circuit refers to a system where signals or information are transmitted within a private, self-contained network, rather than being broadcast publicly. Think of a security camera system in a store: the video feed is only visible to those monitoring the system, not to the general public. 📹 It's like having a private conversation on a secure phone line. Closed-circuit systems offer security and privacy by limiting access to authorized individuals. This is the opposite of open broadcasting.📺
