Configuring UPnP
UPnP allows you to establish the mapping relationship between the LAN and the public network. 
Here you can also add, modify, or remove a UPnP item. 
Preparing for UPnP
1. In the Windows OS, click StartControl Panel  Add or remove programs. 
2. Click Add/Remove Windows Components, and then select Network Services from the 
Windows Component Wizard. 
3. Click Details, then check Internet Gateway Device Discovery and Control client and 
UPnP User Interface. Then click OK to begin the installation. 
4. Enable UPnP from the internet. If your UPnP is enabled in the Windows OS, then the NVR 
can automatically detect it through the My Network Places. 
5. Click UPnP in the Network configuration interface to open the UPnP configuration 
interface.
Interval The interval for sending ranges from 0 to 3600 seconds. 0 
means that there is no interval. 
Note The system will not send an email immediately when 
the alarm occurs. When an alarm, motion detection, or 
video abnormality triggers an email, the system sends 
out the email according to the interval that is specified 
here. This function is very useful when there are too 
many emails activated by events, which might result in 
an overload for the email server. 
Health email enable Click to enable the email health check. The NVR sends a test 
email to check the network connection. 
After enabling Health Enable, you can configure how 
frequently the NVR sends out emails to test the network 
connection. 
Test Click Test to send a test email. A popup message appears to 
indicate the state of the network connection.
