Description

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

Initial position

Moving speed

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.



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.

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

Mirroring

Stretch mode

This specifies the input source resolution.

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.

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.
