SIP
SIP is short for Session Initiation Protocol. If necessary, you can change the default port number, 5060,
to one between 1025 and 65535.
Two way audio port: By default, the two way audio port is set to 5060. Also, it can also be assigned to
another port number between 1025 and 65535.
The Network Camera supports two way audio communication so that operators can transmit and receive
audio simultaneously. By using the Network Camera's built-in or external microphone and an external
speaker, you can communicate with people around the Network Camera.
Note that as JPEG only transmits a series of JPEG images to the client, to enable the two-way audio
function, make sure the video mode is set to H.265 or H.264 on the Media > Video > Stream settings
page and the media option is set to "Media > Video > Stream settings" on the Client Settings page.
Please refer to Client Settings on page 43 and Stream settings on page 70.
