TRVCamControl – a visial component for controling camera movement. TRVCamView – a visual component displaying video from TRVCamera or TRVCamReceiver. TRVCamMultiView – a visual component displaying videos from multiple sources. TRVMicrophone – a component for reading sound from a microphone. TRVMicrophoneView – a visual component showing a microphone activity. TRVCamSender – a component for sending video (from TRVCamera or TRVCamReceiver) and/or audio (from TRVMicrophone or TRVCamReceiver) to TRVCamReceiver or TRVMediaServer via the network. TRVCamReceiver – a component for receiving video and audio (from TRVCamSender or TRVMediaServer) via the network. TRVMediaServer – a component for sending data (video, audio, commands, files) from multiple TRVCamSenders to multiple TRVCamReceivers via the network. TRVTrafficMeter – a component for displaying traffic charts and statistics.
