What system does a monitor require?

1. The system required for a monitor is the monitoring system, also known as a Closed-Circuit Television (CCTV) monitoring system.

2. A typical monitoring system is composed of five main parts: front-end audio and video collection devices, audio and video transmission equipment, backend storage, control, and display devices. The backend devices can be further divided into central control devices and distributed control devices. The front and backend devices can be configured in various ways, and their connections can be established through coaxial cables, twisted pairs, optical fibers, microwave, and wireless means.

Terminal Monitoring Equipment for Monitors

Sequential Video and Audio Switcher: Allows for sequential switching of images and corresponding audio signals from 2 to 12 camera sources. The timing of the image signals is automatically displayed in sequence on the monitor, with adjustable switching intervals.

2. Video Image Processor: The video image processor allows for the simultaneous division and display of multiple images on a single monitor screen, as well as the option to select and display any single image in full screen. It features an alarm input interface that automatically switches to full-screen display of the corresponding camera image during an alarm. Higher-end models come with video playback control functionality.

Matrix Switching Controller: Pre-programmed to control video and manage input/output of alarms.

4. Professional Video Recorder: A single VHS tape can easily record up to 24, 168, or even 960 hours of all camera images and audio signals from the system. Management is straightforward and convenient; during playback, when paired with a video image processor, it can display split-screen images and manually switch to full-screen images of a specific camera; abnormal images can be confirmed during fast playback; upon receiving alarm signals from sensors, the recorder can automatically start or switch to real-time recording; the monitor displays operational procedures and function menus.
