監控前端（采集端）及帶CDMA網卡的筆記本式計算機。這些終端需安裝專用視頻解碼軟件實現移動監控功能。

監控前端系統主要由信號采集設備、可通控動作設備及嵌入式數字硬盤錄像機、網絡視頻服務器及安裝音／視頻壓縮卡的PC式DVR構成。信號采集設備包括音／視額信號、報警信號采集議備及其他模擬采集設備，主要由攝像機、拾音設備、報警器、紅外探頭、門磁、煙霧傳感器等，其作用主要是提供監控前增各種信號采集功能，如視頻、音頻、動、成異常信號及相關參數的采集；可通控動作設備包括電動變焦鏡頭、動、煙務、非法入侵等室外電控防

罩及射燈開關等其他可控機電設備，這些設備按照中心控制端發來的遙控指令進行動作；嵌入式數字硬盤錄像機、網絡視頻服務器及PC式DVR是整個系統中最重要的設備，負責將采集到的音／視頻、報警等模擬信號編碼、壓縮為數字信號，按照標準的網絡通信協議通過局域網、互聯網或專網傳輸到監控中心機房。同時，還可以將監控中心機房發出的數字控制命令轉換為模擬信號指令發給機電、報警等前端設備。整個系統可以做到監控前端無人值守、監控運作高效。

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.
