Port Mapping (Available only in UPnP)
This function can eliminate the need to additionally access the router for port forwarding.
For details, please refer to “Advanced Network Setup” from
www.surveillance-download.com/user/p571.swf
.
Note:
Before using this function, make sure your router supports UPnP, and this function is enabled. If
not, please access your router additionally for port forwarding.
When “Port Mapping” is set to “Enable”, the system will automatically assign an IP address or port number for
you if no IP address or port number is entered.
Note:
When the configurations are saved successfully, you’ll see a message indicating the IP address
and port number assigned to this camera.
3.2.10 RTP
The Real-time Transport Protocol (RTP) is an Internet protocol standard to manage the real-time transmission of
multimedia, such as VLC player.
The media player you want to use for remote access must support RTP transmission for this function to work
normally.
Note:
When you’re about to end the remote access, please press the stop button on your media player
first, and then close the program. This is to ensure the server receives the stop command, and
also help to protect the server from redundant data transmission.
