Configuring NAT (Network Address Translation) Settings 
Purpose: 
Universal Plug and Play (UPnP™) is a networking architecture that provides compatibility among 
networking equipment, software and other hardware devices. The UPnP protocol allows devices 
to  connect  seamlessly  and  to  simplify  the  implementation  of  networks  in  the  house  and 
corporate environments. 
With the function enabled, you don’t need to configure the port mapping for each port, and the 
camera is connected to the Wide Area Network via the router. 
Steps: 
1.  Enter the UPnP™ settings interface. 
Configuration >Network > Basic Settings > NAT 
2.  Check the checkbox to enable the UPnP™ function. 
Note:
