What Dahua, Hikvision and others are using?

Hi

 

I created my own "NVR" with Linux - to capture stream from RTSP I'm using ffmpeg but have few problems which I'm not able to resolve, maybe this is a ffmpeg limitation or other things, nevermind.

 

I thought to buy a NVR, Dahua or Hikvision (If I will not find ano other solution I will do this) but before that I would like to ask you:

 

do you know how those nvr's are capturing the stream? they have own systems or are also using ffmpeg or vlc? Just thinking of creating something similar, or maybe just install similar software/libraries?

 

I just would like to have my own system because then I can create alerts, notifications like I want. Also SSH to NVR is useful

 

Thanks
