Main Introduction To Monitoring Equipment

- Aug 27, 2018 -

A typical TV monitoring system consists of two parts: a front-end device and a back-end device. The front-end device is usually composed of a camera, a manual or electric lens, a pan/tilt, a protective cover, a monitor, an alarm detector, and a multi-function decoder. They perform their respective functions and establish corresponding connections (transmission of video/audio signals and control, alarm signals) with various devices of the central control system via wired, wireless or optical fiber transmission media. In actual TV monitoring systems, these front-end devices are not necessarily used at the same time, but it is essential to realize cameras and lenses that monitor live image acquisition. Back-end devices can be further divided into central control devices and sub-control devices.
