read video stream from IP Address on 80 port assigned to DVR

[C# Programming]

Hi,

I have 4 different cameras located in my home.
These 4 cameras are connected to 4 channel DVR.
DVR store recorded video stream data in raw format on one attached hard disk drive.
I assign static IP address to this DVR, and DVR throws video streams on this IP address and 80 port.

Are there any ways to read video streams from this IP address and 80 port of DVR.

Regards,
Kunal.
