With the progress of the times, people’s living standards have been continuously improved and security has become a topic of more concern to people. You are busy with the use of "mobile video services" to monitor home security at any time, the babysitter care for children; traffic * use "mobile video services" to timely "master" the status of various traffic intersections; out of the company's executives use "mobile "Video applications" to more easily and quickly understand the company's work; business counters, production lines or business premises are all normal operation. The mobile video surveillance system uses China Unicom's public mobile communications network CDMA2000-1X to transmit video and control signals. By installing dedicated video decoding software on a BREW-based mobile phone or PDA with an embedded operating system, users can always Open the phone/PDA anywhere to view the home and company situation and work and travel with confidence. The mobile video surveillance system consists of four parts: a mobile terminal, a transmission network, a management center, and a monitoring front-end.
Mobile terminal (client)
The mobile terminal includes a mobile phone or PDA with a CDMA 2000-1X network, a BREW/WinCE/Linux platform, and a laptop with a CDMA network card.
Monitoring front-end (acquisition side)
The front-end system is mainly composed of signal acquisition equipment, remote control action equipment, embedded digital hard disk recorders, network video servers, and PC-type DVRs. Signal acquisition equipment includes video and audio signals, alarm signal acquisition and other analog acquisition equipment. It is mainly composed of cameras, sound pickup equipment, alarms, infrared sensors, magnetic sensors, and smoke sensors. Its role is to provide various front-end monitoring signals for monitoring. Features, such as video, audio, vibration, smoke, illegal intrusion, and other abnormal signals and related parameters.
Remote-controllable motion equipment includes electric zoom lens, all-round head, outdoor electric control cover and spotlight switch and other controllable electromechanical equipment. These equipments act according to the remote control command sent from the central control terminal.
Embedded digital hard disk recorders, network video servers, and PC-based DVRs are the most important devices in the entire system. They are responsible for encoding, compressing, and compressing analog signals such as video and audio signals collected into digital signals. Internet or private network transmission to the monitoring center room. At the same time, digital control commands issued by the monitoring center room can also be converted into analog signal commands issued to front-end equipment such as electromechanical and alarm. The entire system can monitor front-end unattended and efficient monitoring operations.
Embedded hard disk recorder
Embedded digital hard disk recorder provides audio collection, recording, network transmission, video data can be accessed by authorized users (playback or download); provide alarm signal acquisition, network transmission (active), local linkage; 485 serial port decoder, authorization The user controls the PTZ locally or remotely (presets can be set).
Network video server
The network video server mainly realizes the IP of analog video and audio signals. The digital video signals generated after the analog video and audio signals are digitized are H.264, the digital audio signals are compressed and encoded by G.729, and then the Ethernet interface of the device is used. Low-bit-rate video and audio encoding data is transmitted to multiple remote PCs or network video decoders in the form of IP packets to achieve long-distance transmission, monitoring and storage of video and audio; it also supports remote cloud mirror control and remote alarm management. The network video server communicates based on the IP network protocol and supports multiple access methods such as Ethernet, ADSL, Cable Modem, and dial-up modem; video and audio data can be transmitted over local area networks, wide area networks, and the Internet; and the built-in Web Server can be accessed through Internet Explorer. Directly browse video and audio.
Industrial Controlled Hard Disk Video Recorder
Industrial-Controlled DVR (PC-BASED DVR) uses IPC as the basic hardware and WINDOWS operating system as the basic software. It is equipped with video and audio compression board cards. It uses professional compression algorithms and PC hardware and software capabilities to implement video and audio signals for surveillance systems. Equipment for recording and playback. The core equipment of industrial control DVR is video and audio compression card.
transporting network
Front-end monitoring equipment (DVR, network video server) data upload channels will use IP networks, such as LAN, broadband access, ADSL dial-up, etc. to achieve data upload. For a few applications that cannot be uploaded through wired channels, 5.8 can also be used. G wireless broadband equipment, wireless LAN, to ensure the real-time video data acquisition. The data downlink channel of terminal equipment (PDA, mobile phone, and notebook computer) adopts China Unicom's CDMA2000 1X public mobile communication network to achieve real-time video and audio monitoring.
control center
Composition structure
According to the logical functions, the management center can be divided into server groups such as database servers, management servers, streaming media servers, and standby servers.
Database server: The database server provides centralized management of system data. The server uses the MySql database for comprehensive data management and is mainly used for the negotiation of streaming media service support capabilities of mobile terminals. The database system functions include: user account, login information management; DVR video server information management; billing and traffic statistics management.
Management Server: The management server is mainly responsible for interacting with the database to provide business logic control for the entire mobile monitoring system. Its functional modules include establishing and maintaining network connections for multiple clients; authentication and authentication; maintaining users' login sessions; accepting user's server positioning search requests and returning results from the database server; according to the user's monitoring point requirements, the user needs The browsed server data stream is relocated to the client device.
Streaming Media Server: The streaming media server is a server of the mobile streaming media service platform and is a core device for providing streaming media services. It is mainly responsible for video recording and storage of mobile streaming media, real-time streaming media forwarding, and code stream load balancing control.
Standby server: This server can automatically transfer to the service state when the management server or the database server has an unexpected failure, instead of executing management services or database services. According to the database server, streaming media server and management server architecture, one standby server can be set up for each server, and the standby server and the main server form a dual-system hot standby system.
