# General settings
# Settings sidebar
Click the
button in the upper left corner of the control panel.
To select a language go to the Settings → Language section.
# Audio and video settings
In the settings menu, go to the Audio & video → Conferences and calls section. There you can select devices that will be used by the application.
Instead of a camera, you can select an NDI stream available in the local network if this protocol is enabled in the Settings → Tools → Main section.
Go to More subsection to access the following settings:
Select a device to play back application sounds, e.g., an incoming call
Set up echo cancellation (enabled by default)
Enable higher frame rate when previewing video layout in the control panel (disabled by default)
However, if you use a recording device with integrated echo cancellation/AGC mechanisms, we recommend disabling these options in the application to avoid conflicts between the algorithms.
For the echo cancellation algorithm to work properly, you can run an audio test and identify a possible delay. To do this, click Estimate at the bottom of the window.
During the testing, you will hear several audio signals from the selected playback device. When the test is successfully completed, the time of delay will be displayed.
You can run the audio test again by clicking the Restart button, which will replace the Estimate button after the first successful testing.
When selecting 4K video conferencing equipment, read a simple guide to 4K video conferencing in our blog.
# Network settings
Server connection settings are available in the Network section of the settings sidebar. Here you can connect TrueConf Room to a different TrueConf Server instance or TrueConf Online and set the bitrate limit for input and output streams (10 Mbit/s by default).
You can also click on the 
button to display the list of available servers.
If Suppress direct connection checkbox (unmarked by default) is marked, point-to-point video calls will be routed through the server.
# Secure authorization
With the TrueConf Room Pro plan , you can protect the application from unwanted login using a password.
Set out access rules for TrueConf Room in the Security section of the settings sidebar.
Below you can fin our security implementation principles. To learn more about setup instructions, read our article.
# Security levels
There are various security levels:
To limit user access to the network settings, you can set out login rules for administrators
To limit any access to the TrueConf Room control panel, you can set access rules for the user mode.
# Security types
TrueConf Room supports the following types of secure authorization:
Password is a sequence of characters the administrator sets for security reasons. It should be entered manually each time you access the control panel. It is the only login method for administrator mode.
PIN code is a case-insensitive short sequence of characters generated automatically. Not only can it be entered manually, but it is also used to access the control panel via a link. It is a recommended login method for user mode.
Please note that secure login for users is available only if it has been configured for administrators.
The link with a PIN code is represented in the following way: [server]:[port]/[PIN], where:
[server]— the address of a local server started by TrueConf Room (it can be viewed in the browser address bar after authentication)[port]— the port needed for accessing the TrueConf Room control panel.
Example
If TrueConf Room works on the port 80 on a machine with 10.1.1.10 IP address, you will need to use this link http://10.1.1.10:80/ABC to access the control panel with a PIN code.
If you set a PIN code for user mode, the PIN will be embedded in the link on the main screen. This way, you can restrict access for users outside the meeting room, while meeting room participants won't need any additional measures to log in.
# Preferences settings
In the Settings → Preferences section you can change the following settings:
Incoming calls and conference invitation policies
Restore the main screen window when you receive incoming calls

# Main screen view
The main display may be temporarily turned off due to some reason. In this case the OS will move the TrueConf Room main window to the second display. If you want TrueConf Room to switch to the first display automatically as soon as this display is turned on, you need to check the Pin Main Screen on the current display box.
With TrueConf Room Pro, you can adapt the main screen view to your preferences and corporate branding.
In the Main screen section of the settings menu, you can select the elements of the main screen to be displayed.
