Hello deyaanoor and welcome to the MxCommunity forums!
My only other suggestion here, would be to disconnect the T26 from the network/power temporarily and try to ping 192.168.0.19 - to check if another network device is already sitting on this IP address.
If upon reconnecting the T26 you then start to have successful pings - this should assume that you should also be able to access the camera directly via the web browser.
It is worth noting that the subnet for the following should be used:
Factory IP 10.x.x.x - 255.0.0.0
Autoconfig IP: 192.168.0.19 - 255.255.255.0
and that your PC should be using the same subnet range.
I hope this helps
