1. Access the configuration page of your router or Firewall.
2. Reserve an IP Address in your router or firewall that is not used by other computers or
devices connected to your internal network.
3. Make sure your router is configured properly for computer or devices outside of your local
network to access your DVR through your router. To do so, please use the following
method(s): NAT (Network Address Translation), Port Forwarding, DMZ (De-Military Zone),
DDNS (Dynamic DNS). Please refer to your router or firewall user’s manual for reference.
Note: Improper configuration on the router or firewall will prevent you from accessing your
DVR from outside your network.
4. Write down the assigned IP Address of your DVR, Subnet Mask, IP Address of your Router
(Gateway) of your DVR for future reference when configuring the DVR.
Port Forwarding
To access the DVR from a remote computer over the internet via internet browser (Internet
Explorer).
1. Forward Port 80 and Port 9000 in the router attached to the DVR, to the IP address of
the DVR. *If you can’t use HTTP Port 80 due to use or your Internet Service Provider is
blocking it, use a different port like 1024 as the WEB PORT. When selecting a different
port, forward the new port to the IP address of the DVR and change the settings in the
DVR Network settings. You will also need to add the new port to the end of the IP
address in the browser window. For example, if you use port 1024, you add “:1024” to
the end of the IP address.

“Routers List” and select your router from the list of router manufacturers by clicking on
the brand and model number.

different port number)
