Setting External Camera Parameters

Setting External Camera Parameters

When the endpoint is connected to an external camera, you can set the parameters of the camera input port and external camera, such as the exposure mode, white balance, image mode, noise reduction, video format, and image inversion and view the video effect on the display device.

You still need to set the VPT300 camera parameters if any one of the Camera type parameters is set to VTP300 under System Settings > Input/Output > Video Input.


  1. Choose Device Control > Device Control and click the Camera Parameters tab.
  2. Set the external camera parameters listed in Table 4-4.

    Table 4-4  External camera parameters




    Camera input interface

    Specifies the endpoint's video input port to which the camera is to be connected.

    The default value is 1 HD-VI.

    Exposure mode

    Specifies the exposure mode of the external camera.

    • Auto: The external camera automatically selects the optimum exposure and white balance settings based on the ambient environment.

    • Manual: You must manually set the following exposure and white balance parameters:
      • Brightness gain: adjusts the video brightness.
      • Shutter speed: adjusts the shutter speed.
      • Iris: adjusts the aperture size.
    • Iris priority: When you manually adjust the aperture, the camera selects the corresponding shutter rate.
    • Shutter priority: When you manually adjust the shutter rate, the camera selects the corresponding aperture. This mode is mainly used to shoot moving objects.

    The default value is Auto.

    White balance

    Specifies the way to adjust white balance.

    • Auto: The system automatically adjusts white balance.
    • One-push: This is a fixed white balance mode. Once you select this mode, the value is automatically adjusted. This mode assumes that the camera shoots a white subject occupying more than 1/2 of the image, under correct light conditions. The mode is lost when the endpoint is powered off. You have to reset this mode after the endpoint is powered on.
    • Manual: You need to manually adjust white balance.
      • Red gain: adjusts the brightness of red signals.
      • Blue gain: adjusts the brightness of blue signals.

    The default value is Auto.

    Video mode

    Specifies the output video display effect.

    • Standard: reproduces video more faithfully.
    • Vivid: delivers brighter video with cooler colors.
    • Natural: delivers video with warmer colors.
    • Custom: delivers video with custom settings. After you select this option, you can set the following parameters.
      • Aperture: sharpens video edges and contours to preserve the impression of clarity and fine details. Over-sharpening will make video less realistic.
      • Brightness: specifies the video output level that changes the brightness of the video displayed on the monitor.
      • Contrast: Adjusts color levels to facilitate the distinction between two colors. If the contrast is higher, the difference between the light and dark extremes of a color is more distinct.
      • Hue: adjusts the video color.
      • Saturation: adjusts the grayscale of each color. The higher the saturation, the brighter a color.

    The default value is Standard.

    Noise reduction

    Removes noise artifacts from video. A larger value causes the video to have less noise but detail may also be lost.

    The default value is Low.

    Automatically set output resolution

    Specifies whether the camera automatically sets the video output resolution.

    The default value is Disable.

    Video resolution

    Specifies the video output resolution for the camera. This parameter is available only when Automatically set output resolution is set to Disable.

    The default value is 1080p 60Hz.

    Image inversion

    Specifies whether the video input from the camera is rotated by 180 degrees. When the camera is hung, set this parameter to Enable.

    The default value is Disable.

    VPT300 parameters adjustment

    Voice tracking mode

    Specifies the voice tracking mode of the camera. The options are as follows:
    • Auto: The VPT300 automatically rotates to the direction in which voice comes. When no one is speaking, the VPT300 automatically adjusts its focal length based on the number of participants to present a panoramic view.
    • Autoframe: The VPT300 automatically detects the number of participants and adjusts the focal length of Default camera (that is, the camera to be controlled) to present a panoramic view of all participants.
    • Manual: In this mode, you need to manually rotate the VPT300.
    • Auto(No autoframe): The VPT300 automatically rotates to the direction in which voice comes.
      The difference between Auto and Auto(No autoframe) is as follows:
      • In Auto mode, the focal length changes during video switching.
      • In Auto(No autoframe) mode, video is directly switched without any focal length changes.

    The default value is Auto(No autoFrame).

    Default camera

    A VPT300 has two cameras. One lies on the left, and the other on the right. This parameter specifies the camera to be controlled.

    This parameter is available only after you set Voice tracking mode to Manual or Autoframe.

    The default value is Left.


    Select the sensitivity for the VPT300's voice tracking function. That is, the VPT300 takes close-up video images of a speaker after the speaker talks for the following duration:
    • High: 3-5s
    • Medium: 5-8s
    • Low: 10-20s

    This parameter is available only after you set Voice tracking mode to Auto, Autoframe, or Auto(No autoframe).

    The default value is Medium.

    Combination layout

    Specifies the video layout of the voice tracking camera. The options are as follows:
    • Full screen: Video of the speaker is displayed in full-screen mode.
    • PiP: The panoramic view is displayed in full-screen mode, and the speaker view is displayed in the small window.
    • 2-pane: Two speakers are displayed in two separate panes.

    This parameter is available only after you set Voice tracking mode to Auto or Auto(No autoframe).

    The default value is 2-pane.

    PiP window position

    Specifies the position of the PiP window.

    This parameter is available only after you set Screen layout mode to PiP.

    The default value is Upper right corner.

    Connection type

    Specifies the mode in which the VPT300 obtains an IP address.
    • Static IP: The network administrator assigns an IP address to the VPT300. If you select this option, you must also set Camera IP, Subnet mask, and Gateway address.
    • Dynamic IP: When a DHCP server is available on the network, the endpoint automatically obtains an IP address using the Dynamic Host Configuration Protocol (DHCP).

    The default value is Static IP.

    Camera IP

    Specifies the IP address of the VPT300.

    The default value is


    The VPT300 IP address must be an IPv4 address.

    Subnet mask

    Specifies the subnet mask of the VPT300.

    The default value is

    Gateway address

    Specifies the gateway address of the VPT300.

    No default value is set for this parameter.

    Upgrade password

    Specifies the upgrade password of the VPT300.

    This parameter contains 8 to 32 characters. In addition, it must include at least two of the following: uppercase letters, lowercase letters, digits, and special characters.
