hi, first you need a static IP where you want to configure DVR and Cams, Now you just forword the ports on which your DVR is set. You can forword the ports from router configuration http://192.168.1.1/

After this you add these ports in windows firewall settings and allow them to flow data in and out.


Then you can see you cam from remote computer
example : http://ip:Port/
http://111.222.333.444:9999/

bye
