To watch the live view of NVR remotely, you need to do port mapping for your NVR. 

  • You can modify the port number to any numbers if it is not conflict.

There are two kinds of port mapping, Virtual Servers is applicable to the case of more than one device connected to the router needed to be shared. DMZ is mainly suitable for only one device.

Virtual Servers

Take the 4K NVR For example,

Virtual Servers

1. Make sure the NVR is connected to your router.

2. Login the NVR web management, change the HTTP port number to 8081. Change the RTSP port to 5554.

Figure 1 Network setting of NVR

3. Access to the router’s LAN IP address, in this example the IP is”192.168.1.1”.

4. Once logged into your router, follow the tips below. Fill in the following information(The corresponding external port needs to be configured on the router)

5. The same as HTTP, add a new rule of RTSP.

For example,

DMZ

In some special cases, we need to fully expose a local area device to the WAN, we can set the device as DMZ mode. So enable the DMZ mode in the [DMZ], input the IP of the NVR to make the DMZ work. In this way, computer with internet can visit all the ports of the NVR by entering the router’s WAN IP.

DMZ

Figure 4 DMZ setting

Check out：

Visit the WAN IP for example http://117.29.166.6:8081, so that you can visit the NVR of 192.168.1.161 in this LAN.

Figure 5 Testing

Add the WAN IP for example http://117.29.166.6:8081, to your M-Sight Pro app, fill the 8081 to the port. So that you can visit the NVR of 192.168.1.161 on your phone.

Figure 6 App testing

Note: 

1.  It’s better to keep the internal (private) port and the external (public) port the same.

2.  Some ISP may block the 554 port, so it is recommended to use other ports instead.

3.  Make sure both HTTP port and RTSP port are mapped.

  • (Due to camera usually established via HTTP connection but the video streaming is transferred via RTSP. So if you could access NVR web interface but cannot get the live view stream,or if you can get the live view stream on the NVR web interface but cannot get the live view stream on CMS/M-Sight pro APP.It should be due to RTSP port issue, you could check if the RTSP port is mapped correctly or it's 554 or not.)
