DVR System OS and Firmware

Recommended Posts


I need help with my Sannce NVR System. I wan to get on the operating system (guess Linux based).

Is there a way to open a Service Port like SSH to get on it. Port 80 is the only open Port for HTTP.

Why i want that, i would liek to hack the amount of Cameras from 4 Channel to 6 or 8!

The Protocoll Standart is N1, what does that mean. I have managed to add a ONIVF cam by deleting one, but that camera is not getting Recorded, why?

There are somany Parameters i cant get my head around it.

Or is there a way to upload a diffrend OS on the NVR even by a serial connection like i do with Arduino and Wemos Boards?

Thank you,

Hi. It is not just about software you would also need to alter hardware 


it would be pointless trying to do what you want to do


NVRs are the cheapest part of a system now just buy a new 8 way
