In my first post I asked for help to locate the firmware, since I got no answer had to spend several hours looking for the latest firmware, Then I was reading on one of the forums that linked the firmware to a European website and it worked, It's not just finding the firmware, the whole process was a pain for me because it's the first time experience.
Now I have a very minor problem, I no longer can access the NVR web interface, I got an error message saying "Network Abnormal" I don't know if it's the firmware or the fact that I had to change my password to a strong one, I will have to spend some more time researching this unless someone here experienced it already that can shed some light.
