The lens surface is not clean, with dust, fingerprint, or mist on it.

The distance between the object and the camera is less than 0.7 meters, or
the camera angle is improperly set.
The Huawei VPC800 supports the Video System Control Architecture
(VISCA) protocol and thereby can be cascaded.
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 VISCAM 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 cascaded.
The VISCA protocol supports cascading 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.
