[IVS-2120] Why there is blank screen or very slow video when audio is enabled.

1. Your connection to the device does not have enough bandwidth to support a higher frame rate for the streamed image size. Try reducing the video streaming size to 160 x 120 or 320 x 240 and/or disabling audio.
2. Audio will consume 32 kbps. Disable audio to improve video. Your Internet connection may not have enough bandwidth to support streaming audio from the device.
