Having taken the above steps, you should be able to log in to the IP camera from a remote location by
entering the DDNS address or the static IP address in the location field of a web browser (depending on your
configuration). For example, in this case, you should enter "http://61.220.20.16:80" into the location field of
Internet Explorer to access the IP camera.

Notice!
If you have multiple IP cameras installed on a network, you will need
to change the HTTP and RTSP port on them manually so each one of
them will use a different port. E.g. changing the HTTP and RTSP port
for the 2nd device to 81 and 554 respectively and accessing the 2nd
device by logging on to http://61.220.20.16:81.
