Morphology
closed-circuit + television
The meaning is directly compositional: 'closed-circuit' describes a circuit that is closed/limited and modifies 'television', so a learner who knows 'closed', 'circuit', and 'television' can infer a TV system whose signals are sent only within a limited network (not for public broadcast). This matches common cross-linguistic patterns (many languages have an equivalent term or acronym like CCTV), making the expression immediately understandable from its parts.
Etymology
Closed-circuit television comes from the idea that closed and circuit mean the TV pictures travel in a closed loop of wires to only a few screens, not out to the public. That's why it means a private TV system used 'to watch' people or places to keep them safe.
