What Is a CCTV Camera?
Closed-circuit television monitoring system (English: Closed-Circuit Television, CCTV for short) is an important part of the security technology prevention system, and it is an advanced and highly integrated defense system.
CCTV surveillance system
- The CCTV monitoring system can reflect the screen of the monitored and controlled object in real time, image, and reality in places where people cannot directly observe, and has become an extremely effective observation tool for people to monitor in modern management. Because it has the unique function that only one person needs to operate in the control center to observe many areas, even long distance areas, it is considered a necessary means for security work.
- CCTV surveillance system can provide close observation, monitoring and control of some important areas. The system complies with relevant national technical specifications. Generally, a television camera should be set in the system to achieve all-round monitoring. The main equipment of the system should be equipped with TV monitor, time lag
- The main equipment of CCTV:
- 1. Camera: In the system, the camera is at the forefront of the system. It converts the light image of the set object into an electrical signal-a video signal, and provides a signal source for the system. Therefore, it is one of the most important equipment in the system.
- 2. Camera lens: camera
- Main technical requirements of CCTV surveillance system
- The technical requirements of the CCTV monitoring system are mainly: the definition of the camera, the transmission bandwidth of the system, the signal-to-noise ratio of the video signal, the strength of the video signal, the standard of the TV signal, the function of the camera to achieve high picture quality and operation, and the system The environmental fitness of the device.

CCTV Surveillance System Introduction
- The market and technology development of CCTV surveillance systems are developing rapidly, and practical examples of TV surveillance systems can be found in almost all areas of society.
- From the practical point of view, this book gives a detailed introduction to the principles of all equipment in the CCTV monitoring system and its use methods. Among them, CMOS image sensor technology, related double sampling (CDS), ultra-dynamic and intelligent in the new DSP camera. Backlight compensation and other technologies, aspherical optical lens technology, multimedia monitoring system and its application software, remote monitoring technology based on various broadband networks, digital hard disk video recording and embedded applications are all new in TV monitoring systems in recent years. technology. The book is accompanied by a large number of schematic diagrams and physical diagrams, and also gives some application examples, and strive to make this book as broad and effective reference as possible for the majority of readers.
- This book is mainly intended for engineering and technical personnel and managers engaged in security prevention technology, computer system integration technology, and cable television technology. It is also suitable for users and security personnel of units that have or are preparing to install closed-circuit television monitoring systems. It can also be used as a college School-related professional student reference or vocational training materials.
