Introduction
How to Use
Audio communication
The camera supports two-way audio communication in the MPEG-4 mode so that
operators can transmit and receive audio simultaneously. By using the camera's
microphone input and an external speaker, you can communicate and give
instructions to people at the camera's location.
Note: Audio communication does not work with JPEG because JPEG only transmits
a series of images to the client.
Click
to enable audio transmission to the camera; click to adjust the volume
of microphone; click
to turn off the audio. To stop talking, click again.
