What are the components of the monitoring system

BCDE [Analysis] The monitoring system can be divided into ten subsystems according to its functions: traffic signal monitoring system, video surveillance System, emergency telephone system, fire alarm system, tunnel ventilation control system, tunnel lighting control system, power supply and distribution monitoring system, dispatch command telephone system, wired broadcasting system, special vehicle monitoring system.

[Answer]: The video surveillance system is generally composed of four main parts: the camera subsystem, the image transmission subsystem, the control subsystem and the display recording subsystem.

The components of the video surveillance system include monitoring front-end, management center, monitoring center, PC client and wireless bridge.The description of each component is as follows: (1) Monitoring front-end: used to collect the monitoring information of the monitored point, and can be equipped with alarm equipment. 1 Ordinary camera + video server.

The monitoring system is mainly divided into four categories: front-end equipment, transmission equipment, main control equipment and display equipment. This article will introduce the specific contents of these four types of equipment in detail. Front-end equipment The front-end equipment mainly includes cameras, supplementary lights (2 types of infrared and white light), 12V power adapters, waterproof boxes, etc.

I, the camera part is the cutting-edge part of the TV monitoring system, which is the "eye" of the whole system. Second, the transmission part is the image signal path of the system. Third, the control and recording part is responsible for the control of the camera and its auxiliary parts (such as lens, gimbal), and the recording of images and sound signals.

Security monitoring system configuration recommendation

1. The security monitoring system mainly includes the front-end part, transmission part, control part, TV wall display part, anti-theft alarm part, and system power supply part.

2. In small security monitoring systems, our most common transmission layer equipment is video cable and audio cable. For medium and remote monitoring systems, we often use radio frequency cables and microwaves. For remote monitoring, we usually use the Internet, a cheap carrier.

3. If necessary, other accessories, such as infrared sensors, door and window sensors, etc., can be installed to enhance the function of the home security monitoring system. Installing a home security monitoring system requires certain skills.And professional knowledge, it is recommended to find a professional security company or technical personnel to install and configure to ensure the stability and security of the system.

4. Monitor: a device used to display surveillance images or videos. It can be a single screen or multiple screens, and can be configured as needed, such as picture splicing and split-screen display. Other auxiliary equipment: such as video distributor, video amplifier, signal converter, power supply box, UPS and other accessories.

5. To build a network video surveillance system, the following equipment is required: webcam; 2. Gather switch core switch network hard disk recorder platform server. If you need a splicing screen, you also need a high splicing controller.

What equipment is the security monitoring system composed of?

The video security monitoring system generally consists of four main parts: front-end, transmission, control and display records.

The monitoring system is generally composed of a front-end camera and a back-end software system. Camera, lens, gimbal, intelligent spherical camera. Video transmission system: transmission cable, optical fiber transmission, common cable transmission, twisted pair transmission, wireless transmission, power carrier transmission, etc., terminal display system.

Transmission part: mainly composed of coaxial cable. The transmission part requires real-time transmission of the images recorded by the front-end camera. At the same time, it requires the transmission to have small loss and reliable transmission quality, and the image can be clearly restored and displayed in the video control center.

Front-end equipment: camera, gimbal camera (the one that can be turned) power adapter.

Hello: The video security monitoring system is composed of the following points image acquisition - infrared camera (outdoor rain gun type, outdoor rainproof tube type, 360° gimbal, indoor hemisphere, etc.) signal, power supply transmission - power supply (AC 220V, 48V, 24V, DC 24V, 12V Wait).

Security monitoring systemThe composition of the system and its functional analysis

Control layer The control layer is the core of the entire security monitoring system, which is the clearest embodiment of the scientific and technological level of the system. Usually, we have two control methods - analog control and digital control.

High-definition network digital monitoring system of intelligent security High-definition network digital monitoring system is composed of a network high-definition hard disk recorder and multiple high-definition digital cameras. It mainly installs multiple high-definition digital infrared night vision cameras around the villa mansion, configures ground sensing coils, and realizes automatic tracking and Automatic alarm, safe, reliable, beautiful and generous.

. Control part: This part is the core of the security monitoring system, which completes the digital acquisition of analog video surveillance signals, monitoring data recording and retrieval, hard disk recording and other functions. The control part is the key part to realize the linkage of alarm and video recording.
