Idle Session Settings

      1. Specify the maximum time limit allowed, for the remote session to be idle
      2. Specify the action that needs to be performed when a remote session's idle time limit exceeds, such as disconnect the remote connection or disconnect and lock the remote computer.

Configure Screen Recording

Screen recording enables you to record the entire remote control session that can be used for auditing purposes. This feature is currently supported only for windows operating system. Given below are the operations performed when you have enabled screen recording:

  1. When you connect to a computer, the Desktop Central Agent on the computer to which you connect will check for the available hard disk space for saving the video.
  2. If sufficient space is available, the session and recording will start and a notification will be displayed on the client computer that this session is being recorded (configurable)
  3. After the session is completed, the recorded video is uploaded to the Desktop Central Server. The recorded video is available under the History tab available within the Remote Control tool.

To enable and configure Screen Recording, follow the steps below:

  1. Click the Tools tab
  2. Click Remote Control
  3. Select the Screen Recording tab
  4. Select the "Enable Screen Recording" check box and specify the following
    1. Select the required Codec that have to be used for compression and decompression of the video. If the selected Codec is not available on the remote computer, the default codec will be used.
    2. Specify the Frames per Second. The higher the frames per second will give you a smooth mouse movements, while it also increases the size of the video. If it is just for auditing purposes, it is better to leave it with the default value.
    3. Choose the required color quality. Higher the color quality the broader, would be the range of color depth, but also increases the size of the video.
    4. Specify the maximum storage size for the recorded videos. When the storage limit exceeds, the previously recorded files are automatically deleted to increase the free disk space.
    5. Specify what should be done when the disk runs out of free space on the remote computer, when the session is in progress. You can either choose to stop the recording and continue with the session or disconnect the session.
    6. If you wish to notify the users that the remote control session is being recorded, select the "Enable User Notification" checkbox and specify the message and notification duration. If you want the notification be permanently displayed throughout the session, select "Always show a notification when recording is in progress" option.

Configure Performance

You can configure the following performance settings to increase the performance of remote session:

  1. Compression Settings (this is not supported for Mac computers)

Compression settings includes the following options:

      1. Fast: Use this option, when you want the rendering to be faster. The compression ratio will be lower and will consume higher bandwidth comparatively.
      2. Best: Use this option, when you want to optimize bandwidth utilization. The compression ratio will be higher and the User Interface (UI) rendering will be comparatively slower.

   2. Color-quality Settings

Selecting an appropriate color-quality level enables you to use your bandwidth effectively during a remote session. Lowering the level of the color quality will decrease the consumption of your bandwidth. This will ensure effective bandwidth consumption.

Note:  The default settings for performance settings are as follows:

      1. Compression Settings
        1. For LAN (local offices): Fast
        2. For WAN (remote offices):Best
      2. Color Quality

        1. For LAN (local offices): High (16 bit)
        2. For WAN (remote offices):High (16 bit)

    5. Select the required settings for the following from the dropdown boxes:
      1. Compression
      2. Color Quality
    6. Click Save

You have configured the performance settings as required.

Configure User-confirmation

You can send users a message asking for permission to connect remotely to their computers. This option allows you to get confirmation from a user before connecting to their computer. Only Desktop Central users with administrative privileges can configure this option.

If a user is logged in, Desktop Central sends a remote-connection confirmation request for the user's approval. Remote connection is established only if the user approves the request within 30 seconds. If the user does not approve the request within 30 seconds, the remote connection is not established automatically.

If a user is not logged in, the remote connection is established without waiting for a confirmation from the user.

You can also do the following:

  1. Set the amount of time you want to give the user to approve the request to allow a remote connection
  2. Enter the text that you want the user to see when prompted for confirmation to allow remote control
  3. Check the Always Prompt checkbox to send a user-confirmation message to users even if they have logged off or in locked state
  4. Exclude computers from receiving a user-confirmation message

Making User Confirmation Permanent

One of the prerequisites required to comply with HIPAA is to protect user privacy. Therefore, it is mandatory to get the approval of users before connecting remotely to their computers. Making user confirmation permanent will ensure that you always get the user's consent before establishing a remote connection.

If you choose to make user confirmation permanent you cannot revert the settings.

Using Other Settings After Making User Confirmation Permanent

This section comprises information about how other settings like Always Prompt and Exclude Computers will work when user confirmation has been made permanent.

    1. If you enable the Make User Confirmation Permanent option. All the computers in your network will receive a user-confirmation message before a remote connection is established.
    2. If you check the Exclude Computers checkbox after you have enabled the Make User Confirmation Permanent option, the following actions will take place:
      1. All computers in your network will receive a user-confirmation message
      2. Computers in the Exclude Computers list will not receive a user-confirmation message
    3. If you check the Always Prompt checkbox after you have enabled the Make User Confirmation Permanent option, the following actions will take place:
      1. All computers in your network will receive a user-confirmation message
      2. Computers that are locked and users that have logged off will receive a user-confirmation message
    4. If you check both the Always Prompt and Exclude Computers checkbox after you have enabled the Make User Confirmation Permanent option, the following actions will take place:
      1. All computers in your network will receive a user-confirmation message
      2. Computers in the Exclude Computers list will not receive a user-confirmation message
      3. Computers that are locked and users that have logged off will receive a user-confirmation message

Excluding Computers

You can also exclude computers from receiving a user-confirmation message. When you exclude computers from receiving user-confirmation messages, you can connect to them immediately, without an approval from the user.

If you have made the user-confirmation option permanent, check the Exclude Computers checkbox to ensure that the computers in the Exclude Computers list do not receive a user-confirmation message before a connection is established.
