The system is called "closed-circuit" because the cameras, monitors and/or video recorders traditionally communicated across a proprietary cabling system within the building, these days with cloud services available, we more commonly store the video within this secure cloud based service.
Older CCTV systems used small, low-resolution cameras, monitors and Digital Video Recorders (DVRs) with no interactive capabilities. Modern CCTV displays are high-resolution colour, providing the CCTV administrator with the ability to zoom in on an image or track an event (or someone) through the advanced Video Management System (VMS).
