1.
The Huawei Camera 200 supports the Video System Control Architecture
(VISCA) protocol and therefore can be cascaded.
2.
Connection method: Use a keyboard with the VISCA protocol to connect the
cameras. Connect the RS232-IN port of the first camera to the VISCA
keyboard. Then connect the RS232-OUT port of the first camera to the
RS232-IN port of the second camera, the RS232-OUT port of the second
camera to the RS232-IN port of the third camera, and so on. Up to seven
cameras can be cascaded.
3.
The VISCA protocol cascades a maximum of seven cameras. The address
codes are automatically negotiated and increase by 1 with each added
camera.
4.
If control is abnormal, check the cables and their connections. Check that the
keyboard can control the first camera. If the first camera can be properly
controlled but the other ones cannot, check that the cable length does not
exceed 30 meters. If the fault persists, restart the keyboard and the cameras.
