The Cameras tab contains the list of available cameras, DCUs and DAKs (Digital Audio Kits / speakers).
The cogwheel in each row of a configured camera prompts the Camera Settings window to open, where PTZ settings, video size, quality, audio source and gain, and white balance can be adjusted for a specific camera.
The recommended video size (aspect ratio) is 16:9 (e.g. 1280x720).
The sizing of camera streams may not be optimal with a 4:3 video size (an additional black bar/stripe might be visible at the upper and lower edges of the screen).
For cameras without built-in audio, one of the external audio sources has to be selected from the Audio source drop-down, in order the camera to be able to be assigned to a room within LearningSpace.
In case the "use without audio" option is selected, you can assign the camera to a room but the videos will be recorded without audio, which means that in this case audio track will not be recorded.
Speaker Settings 
The cogwheel in each row of a configured speaker (Digital Audio Kit, DAK) prompts the Camera Settings window to open, where the following settings can be specified:
- Name - Speaker name for distinction
- Audio gain (dB) - controls the sensibility of the integrated microphone of the speaker
- Speaker gain (dB) - controls the speaker output volume
