华为视频会议TE60可以同时连接三个摄像机：HD-VI接口可同时连接两个HUAWEI VPC600或者VPC620高清摄像机，DVI-I接口用于连接主摄像机，输入主视频图像。
HD-VI接口标配HUAWEI VPC600/VPC620，连接后，无需其他线缆即可实现对HUAWEI VPC600/VPC620的PTZ控制和供电。
DVI-I接口连接摄像机后，必须将VISCA控制信号线缆连接至终端的COM接口，才能进行摄像机PTZ控制。
登录TE60 Web界面，选择“系统配置 > 输入输出”，单击“视频输入”页签，正确选择所连接的摄像机的类型，和正确选择与摄像机控制接口相连的串口后，才能控制摄像机。
The TE60 can connect to three cameras at the same time. The HD-VI port can be connected to two HUAWEI VPC600 or VPC620 HD cameras at the same time. The DVI-I port can be connected to the center camera for video input.
The HD-VI port is connected to the HUAWEI VPC600/VPC620. After the connection, the HD-VI port can be used to control the PTZ and supply power to the HUAWEI VPC600/VPC620.
After connecting a camera to the DVI-I port, connect the VISCA control signal cable to the COM port on the endpoint.
