You will need to forward the port that the camera is using in the Router to the camera.   By default this is TCP port 80.  From a remote location you would enter in the public or WAN IP address of your Router into your browser or add it to SecurView using the public IP address.

Refer to your Router's user's guide to determine the WAN IP address of the Router and how to forward the port.  

Alternatively you can use Dynamic DNS services to maintain remote WAN connectivity.  Please refer to the Dynamic DNS section of the Knowledge base regarding DDNS.

The following example shows how to forward the port in a TEW-432BRP Wireless Router.

If TCP port 80 is already in use on your LAN the port the camera uses can be changed under Configuration>Network Setup.   If you use any port other than TCP port 80 you must append the port number in the address line when accessing it.  For example, if you use TCP port 81 on the camera you would access the camera as follows. 

https://192.168.10.30:81

The port number is appended with a colon and https:// must be included in the address line.
