Site System Requirements
The front end of the video surveillance system is mainly designed for the card swiping point at each entrance and exit. The video surveillance is performed on the incoming and outgoing personnel, and the hard disk video recorder is connected to the network. All video signals of the hard disk video recorder are managed by the server, so that the video signal of the video recorder can be viewed and managed freely. The monitoring center can design 32-inch or larger large-screen displays based on VR data.
System composition
Hardware platform structure diagram:
The video television monitoring system consists of four parts: camera, transmission, display and control. It is an integrated system that monitors in real time and can be queried afterwards for a high level of protection. Widely used in a variety of different occasions. Through the camera and its auxiliary equipment to directly view all the conditions of the controlled place, and the front camera to capture the image signal to the control center, the video signal distribution, switching, recording and playback and other functions to operate.
Camera section
The camera part is the front part of the TV monitoring system and is the "eye" of the entire system. The gun-type infrared integrated machine must have waterproof and dustproof functions when installed outdoors. Illumination requirements: The system camera for outdoor weather monitoring, monitoring place minimum illumination is color ≤ 0.1LUX, black and white ≤ 0.02LUX. Infrared camera 0LUX (infrared light on). Sharpness requirements: In order to ensure the digital video effects, the camera horizontal resolution color color ≥ 480TVL; black and white ≥ 540TVL.
Transmission section
The transmission part is the channel of the system image signal, sound signal, control signal and so on. Use the national standard video line for transmission
Control section
The control part is the "heart" and "brain" of the entire system and is the command center that realizes the functions of the entire system. The control part is mainly composed of the general console and video host. The control part in this system mainly refers to the monitoring system control software and the display software.
Display section
The display consists of a monitor. Its function is to display the transmitted images one by one.
Video signal storage device
All the video access control system monitoring signals are transmitted to the back-end management center VR DVR through the signal line for video recording. The video access control system storage time is at least 30 days.
DVR can set operator code, password, operation level and priority. Set up sequence switching and alarm mode. Set to display the date, time, camera number, camera title, and event information in characters. Set the DVR to see the menu status of any camera and remote software upgrades and programming.
The hard disk recorder is connected to a local area network. According to the authorization management, remote monitoring can be performed.
Digital hard disk recorders can select single-screen, multi-screen real-time monitor images on the monitor. Record mode can be selected for recording, all required to achieve 1 format, 25 frames / sec storage. Video playback can be intelligently searched, fast, medium, slow, and specified time (accurate to second) playback and other settings. The playback image can be arbitrarily selected to be displayed on the monitor with a single screen and multiple screens, and has an electronic zoom function. Live, recording, and playback are performed simultaneously.
Digital hard disk recorders through the 16-port network switches form an internal 10/100Base-T network topology, and digitize the images via the TCP/IP protocol, through an embedded video server, to prepare for networking with a higher-level center. After the conditions are mature and connected, they can remotely look at any surveillance image of the community at the police station, branch office, and city hall through authorization, and view the video recording.
Digital hard disk recorder Internet can be authorized, hierarchical management, control of operating power, increase system privacy and security. Digital DVR images are saved for 30 days.
