Question Do the cameras support daisy chain cascade control? If daisy chain cascade
control is supported, how are the cameras connected and controlled? How are the
camera address codes set? Why cannot the cameras be controlled after they are
connected?
Answer The Huawei VPC800 camera supports the Video System Control Architecture
(VISCA) protocol and cascade control.
Connection method: Use a keyboard that supports the VISCA protocol to
connect the cameras. Connect the VISCA IN port of the first camera to the
VISCA keyboard. Then, connect the VISCA OUT port of the first camera to the
VISCA IN port of the second camera, the VISCA OUT port of the second
camera to the VISCA IN port of the third camera, and so on. A maximum of
seven cameras can be connected in this serial connection mode.
The VISCA protocol supports cascade control of a maximum of seven cameras.
The address codes are automatically negotiated and increase by 1 from the first
camera to the seventh camera.
If the control is abnormal, check the cables and their connections. Ensure that the
cables and their connections are normal. Ensure that the keyboard can properly
control the first camera. If the first camera can be properly controlled but the
other ones cannot, check the cable length. Ensure that the cable length does not
exceed 30 meters. If the fault persists, restart the keyboard and the cameras.
