Hello I hope you are fine.
I have a problem, the hard drive is damaged and I can not recover the information. I need help to be able to install the firmware on a new ssd disk.

got problem that my NVR does not recognize ipc, only one. There are 4 cameras and only one can I get a picture
I would like to upgrade the system and they are fine if you send the FW for my system. Tried resetting the NVR but it didn’t help.
My system is K9604-W NVR. So I need FW so I can upgrade via USB.
Thanks so much
