监控前端(采集端)及带CDMA网卡的笔记本式计算机。这些终端需安装专用视频解码软件实现移动监控功能。

监控前端系统主要由信号采集设备、可通控动作设备及嵌入式数字硬盘录像机、网络视频服务器及安装音/视频压缩卡的PC式DVR构成。信号采集设备包括音/视额信号、报警信号采集议备及其他模拟采集设备,主要由摄像机、拾音设备、报警器、红外探头、门磁、烟雾传感器等,其作用主要是提供监控前增各种信号采集功能,如视频、音频、动、成异常信号及相关参数的采集;可通控动作设备包括电动变焦镜头、动、烟务、非法入侵等室外电控防


罩及射灯开关等其他可控机电设备,这些设备按照中心控制端发来的遥控指令进行动作;嵌入式数字硬盘录像机、网络视频服务器及PC式DVR是整个系统中最重要的设备,负责将采集到的音/视频、报警等模拟信号编码、压缩为数字信号,按照标准的网络通信协议通过局域网、互联网或专网传输到监控中心机房。同时,还可以将监控中心机房发出的数字控制命令转换为模拟信号指令发给机电、报警等前端设备。整个系统可以做到监控前端无人值守、监控运作高效。


Monitoring front end (acquisition end) and notebook computer with CDMA network card. These terminals need to install special video decoding software to realize mobile monitoring function.
The monitoring front-end system is mainly composed of signal acquisition equipment, general control action equipment, embedded digital hard disk video recorder, network video server and PC DVR with audio / video compression card. Signal acquisition equipment includes audio / visual signal, alarm signal acquisition equipment and other analog acquisition equipment, mainly composed of camera, sound pickup equipment, alarm, infrared probe, door magnet, smoke sensor, etc. its function is to provide various signal acquisition functions before monitoring, such as video, audio, dynamic, abnormal signal and related parameters; The action equipment that can be controlled includes electric zoom lens, motion, smoke, illegal intrusion and other outdoor electric control anti-theft devices
Cover, spotlight switch and other controllable electromechanical equipment, which act according to the remote control command sent by the central control end; Embedded digital hard disk video recorder, network video server and PC DVR are the most important equipment in the whole system. They are responsible for encoding and compressing the collected analog signals such as audio / video and alarm into digital signals, and transmitting them to the computer room of the monitoring center through LAN, Internet or private network according to the standard network communication protocol. At the same time, it can also convert the digital control command sent by the computer room of the monitoring center into analog signal command and send it to electromechanical, alarm and other front-end equipment. The whole system can achieve unattended monitoring front-end and efficient monitoring operation.
