Help to set up ports for Hikvision IP camera in another location than the NVR

[Rekal]

I have a Hikvision NVR at home.
There are 3 cameras for home surveillance.
However, I also have 1 camera at the office.
Can I get the image from the office camera on my NVR at home?

That way my wife (who is at home) can see when I'm in the office.
At the moment I can't get it set up.

At the office I had 3 ports opened in the modem
8442, 8443 & 8444 these are confirmed open.

(below are example IP addresses)
Home IP (fixed): 95.110.50.50
IP office (fixed) : 94.110.50.60

I would like to set the following ports:
HTTP : 8442 (default 80)
RTTSP : 8443 (default 554)
SERVER : 8444 (default 8000)

I have set the following on the camera:


On the NVR following :


I can surf the office camera web page just fine from home or outside by going to : 94.110.50.60:8442
But the connection in the NVR says: parameter error.
The camera has already been set to factory settings twice, am I doing something wrong?
