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:
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.264 or H.265 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 31 and Stream settings on page 63.
