As per the admin of the router: ""...I have spent at least three hours today doing some extensive research on the camera system. I have check with the high speed cable provider and the ports are not being block on their end both for incoming and outgoing. I have also spent time opening port range and still there was no connection on ports 4550 and 5550.
On port 81 there is connections both and sync and acknowledgement, i.e. the camera system is acknowledging connection
On port 4550 there is sync but no acknowledgement; i.e nothing is waiting on that port..."
So as per your earlier recommendations, we have the windows firewalls open, IP number is correct and we add XX.XX.XX.XX:81 at the end of the IP number. I checked on www.canyouseeme.org and only the port 81 is visible....but this conflicts with what the guy administering the router says! It looks like he has spent some time on it and he says the ports are open...
Is it somehow possible that I have restricted the 4550 and 5550 Geovision ports inadvertantly?
Thanks for your help again.
