If you are unsure of the IP Address of the camera, you can click on
Search to search for all available cameras that are installed on your
local area network.
Note: Only cameras on your local area network can be located using Search
in IPView SE. If you want to add a camera via the Internet, you must enter
in a public IP Address. Please note that if your camera is behind a router,
you will need to enter your router's WAN IP followed by a colon, then the port
number that is assigned to your camera. As in example 10.10.10.80:800,
where 10.10.10.80 is your router's WAN IP and :800 is the port that your
camera is using.
Highlight the camera you wish to add and click on Add. The
camera will automatically be added into the IPView SE list view.
If you add the same camera more than once you will receive the
following message (see below).
