hickvision cctv - static port mapping

[walla]

I have been trying to set up hickvision cctv remote access on my new Vodaphone router.  I have added 3 entries for the 3 ports I need access.  When I try to apply the settings I keep getting the message - 

Corrections needed Duplicate Ports Found

Please can someone advice, many thanks

Just to clarify:

Each camera has it's own different port?

or

All cameras use the same port?

I suspect the second, which won't work as port forwarding will only send one port to one ip.

@walla Hikvision has been discussed before, did you look at those threads?
