Troubleshooting
Question Why can't I use PTZ to control the camera from an HD videoconferencing
endpoint?
Answer The serial connection between the camera and the HD videoconferencing
endpoint is incorrect.
The serial port of the HD videoconferencing endpoint type is set incorrectly.
Question Why does the camera fail its startup diagnosis along with one of the following
symptoms: 1) The camera fails to start. 2) The PTZ generates abnormal noise. 3)
Nothing is displayed on the camera screen?
Answer A nonstandard power adapter may be used. The standard one provides a 12 V DC
output.
The connector at the low-voltage side of the camera's power adapter has been
reconstructed, or the cable of this power connector has been extended. If the
cable of the camera adapter is not long enough, extend the cable of the power
socket.
Question Why is the camera video not displayed on the display connected to the HD
videoconferencing endpoint?
Answer The HD videoconferencing endpoint and camera are not connected correctly.
The input and output settings on the HD videoconferencing endpoint are
incorrect.
The HD videoconferencing endpoint does not support the camera's video format.
The display does not support the video output format set on the HD
videoconferencing endpoint.
Question Why does the display fail to display any video after the camera has worked for a
period?
Answer Check the camera's working environment. For example, check whether the
cables are connected securely, whether the voltage is stable, and whether heat is
dissipated properly.
Question Why is the camera video displayed unclearly or why cannot the camera
automatically adjust its focus after the camera is powered on?
Answer The lens surface is not clean, with dust, fingerprint, or mist on it.
The camera is not in autofocus mode.
