摄像部分是安装监控系统的前沿部分，是整个系统的“眼睛”。在被监视场所面积较大时，在摄像机上加装变焦距镜头，使摄像机所能观察的距离更远、更清楚；还可把摄像机安装在电动云台上，可以使云台带动摄像机进行水平和垂直方向的转动，从而使摄像机能覆盖的角度更大。
The camera part is the front part of the monitoring system and the "eye" of the whole system. When the area of the monitored area is large, the zoom lens is added to the camera to make the observation distance farther and clearer. The camera can also be installed on the electric platform, which can drive the camera to rotate horizontally and vertically, so that the camera can cover a larger angle.
