	Camera type	This specifies the type of the camera connected. The terminal supports
		camera models from multiple manufacturers. The control commands
		vary with different cameras. Therefore, select the camera type
		correctly to ensure that the camera can be controlled properly.
	Serial port	This specifies the serial port that is connected to the camera control
		interface. You can select either COM1 or None.
		Select the serial port that is being used. Otherwise, the camera cannot
		be controlled.
	Initial position	 If Auto is selected, the camera automatically determines its initial
		position after startup. Generally, the camera keeps its original
		position.
		 If camera presets have been defined, such as Preset 1, the presets
		can be selected. Then the camera moves to the corresponding preset
		after startup.
	Moving speed	This specifies the speed for turning the camera and moving the camera
		lens.
		 Select Slow for accurate positioning.
		 Select Fast for quick positioning.
		 Select Medium for medium pace positioning.
	Input source	This specifies the input source resolution.
	Mirroring	This specifies whether the terminal displays a reflection of an input
		video, wherein the right and left sides of the original are reversed. By
		default, Normal is selected. If the terminal is used in a Huawei
		telepresence system, select Horizontal mirroring.
		 Normal: The input video will not be reversed.
		 Horizontal mirroring: The terminal displays a reflection of the
		input video, wherein the right and left sides of the original are
		reversed like the reflection of something seen in a mirror.
	Stretch mode	The terminal adjusts the input video based on the encoding format of
		the video.
		 Stretch: Stretch the video to full-screen mode without locking the
		aspect ratio of the video.
		 No stretch: Stretch the video to full-screen mode after locking the
		aspect ratio of the video. Black borders may appear at the four sides
		of the video display.
		 Intelligent stretch: The system cuts the video to a proper size, and
		then stretches the video to full-screen mode after locking the aspect
		ratio. For example, to change a wide-screen video to a
		narrow-screen video, the system cuts the left and right sections of
		the wide-screen video, and then stretches the video to full-screen
		mode.
