Briefly describe the composition and principle of high-definition network video surveillance system

The monitoring system consists of four parts: front-end system, transmission system, control system and display storage system, and also has the transmission of image signals. , storage, processing, and other functions.

In the analog era, the transmission part generally adopts coaxial cable and optical cable, which is composed of a closed-loop system, that is, only this unit can be provided for use.

The main purpose of the video transmission part is to transmit the video images captured by the camera to the monitoring center. The transmission methods commonly used in video surveillance systems include coaxial cable transmission, twisted pair transmission, optical fiber transmission, wireless transmission and so on. Video management part The main products of the video management part are hard disk recorders, video capture cards, monitoring software, etc.

The monitoring system is composed of 5 major parts: camera, transmission, control, display and record registration. The camera transmits the video image to the control host through the coaxial video cable, and the control host then distributes the video signal to each monitor and video recording device. At the same time, the voice signal to be transmitted can be synchronously entered into the video recorder.

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.

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).

What are the monitoring system architectures

The monitoring system is generally composed of front-end cameras and back-end software systems. 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.

Traditional video surveillance is divided into front-end video acquisition part (camera), transmission part (cable), storage part (hard disk recorder), display part (monitor or splicing screen) and control part (control software and hardware).

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

The video surveillance system consists of five parts: front-end acquisition, transmission, control, display and recording.

Usually, we have two control methods - analog control and digital control. Analog control is an early control method. Its console is usually composed of a controller or analog control matrix, which is suitable for small local security monitoring systems. This control method has a low cost and a small failure rate.

I, the camera part is the cutting-edge part of the TV monitoring system and the "eye" of the whole system.

Smart City Video Surveillance Operation and Maintenance Management Platform Solution

1. Smart City City Video Surveillance Operation and Maintenance Management Platform Solution Chapter 1 OverviewWith the continuous promotion of the construction of urban video surveillance systems, through the construction of urban surveillance cameras in various districts and counties and related systems, the number of cameras in the city has begun to take shape.

2. Based on the actual situation, develop and expand functions: national urban management, construction site environment management subsystem, leader mobile supervision subsystem, urban landscaping management subsystem, vehicle GPS positioning monitoring subsystem, outdoor advertising management subsystem, video monitoring subsystem, sanitation and cleaning management subsystem , business text messages, etc.

3. Closely focus on the fundamental goal of making the lives of the masses better, firmly grasp the central task of building an inter-provincial central city, and accelerate the construction of a safe and controllable new smart city. Zhengzhou City will truly become a livable, workable and travelable city with modern intelligence, humanistic ecology, traditional civilization and modern culture. City.

4. Through the intelligent management web platform of the underground comprehensive pipeline corridor, the staff can clearly see the statistics of operation, maintenance, fault repair and other situations in each cabin by clicking the mouse.

Platform software system architecture of network monitoring software

Platform software is divided into platform support layer, intermediate service layer, public service layer and application layer according to the five-layer architecture. The platform support layer is composed of an operating system platform, a relational database and a network communication protocol.

Traditional video surveillance is divided into front-end video acquisition part (camera), transmission part (cable), storage part (hard disk recorder), display part (monitor or splicing screen) and control part (control software and hardware).

The architecture of the network monitoring system The network monitoring system consists of a camera, a WEB server, a transmission network and a monitoring terminal. The camera is used to capture the video of the monitoring scene. THE WEB SERVER IS THE CORE OF THE WHOLE MONITORING SYSTEM. THERE ARE TWO PARTS: HARDWARE AND SOFTWARE. THE DETAILED STRUCTURE WILL BE INTRODUCED BELOW.

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.

also known as the network video center management system, the English name is Neork video Centermanagementsystem, abbreviated as NV CMS, or directly abbreviated as CMS.

What needs to be considered in the architecture of the high-speed rail video surveillance system

1. First of all, consider the characteristics of the subway industry, clarify the requirements for the quality of monitoring business; clarify the scale of system construction, and whether to support sustainability Capacity expansion construction, whether the comprehensive construction cost needs to be controlled; whether the reliability of the business system will not decline in the case of large-scale deployment.

2. 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. DVR hard disk recording system, IP-SAN, video matrix, picture processor, switcher, distributor.

3. The highway video surveillance system is divided into three parts in terms of geographical location: toll station monitoring system, road section monitoring system, tunnel and special bridge monitoring system. According to the function, it is mainly composed of four parts: front-end camera equipment, transmission equipment, main control equipment and back-end equipment.

4. The video surveillance system consists of five parts: front-end acquisition, transmission, control, display and recording.

5. Surveillance camera: Surveillance camera is the core part of the surveillance system. We need to choose different types of surveillance cameras according to the size and shape of the monitoring area. Video recorder: Video recorder is a device used to record surveillance images. We need to choose the storage capacity and recording mode of the video recorder.

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