To allow a remote PC to connect to the NVR and the IP cameras, do the following:
Step 1. Set up the port mapping (virtual server) on the router.
From Forward to
219.87.144.205:8000 192.168.1.1:80
219.87.144.205:8001 192.168.1.101:80
219.87.144.205:8002 192.168.1.102:80
219.87.144.205:8003 192.168.1.103:80
Step 2. Add the IP camera to the NVR by entering the IP address of the IP camera in the
‘IP Address’ settings. Enter the public IP address of the router and the mapped ports of
the IP camera in the ‘WAN IP Address’ settings.
Note: When configuring the IP camera, the WAN IP and LAN IP must be entered.
To open FTP (port 21) and SMB (port 445) of the NVR on WAN, configure the following port
mapping settings:
From Forward to
219.87.144.205:21 192.168.1.1:21
219.87.144.205:139 192.168.1.1:139
219.87.144.205:445 192.168.1.1:445
After finishing the above two steps, connect to the NVR on WAN by entering the IP address
http://219.87.144.205:8000 in the IE browser. Then login the NVR with the correct user
name and password.
If the port specified to the NVR is 80, enter http://219.87.144.205 to connect to the NVR.
Note: If the router does not use a fixed IP, configure the DDNS settings on the router.
Other configurations are the same as above.
