It possible to work on both systems, if there is no Tkinter it starts with a console interface DVR-IP, NetSurveillance or 'Sofia' Protocol I also tried to replicate the communication by sending some previously stored communication data to the DVR and watching its response.Python library for configuring a wide range of IP cameras that use the NETsurveillance ActiveX pluginĭeviceManager.py is a standalone Tkinter and console interface program such as the original DeviceManager.exe

Sorry I wrote this report after the whole process so I can’t write all steps (commands) one by one, but what I was doing was storing the communication and trying to separate out some parts of it and then find out what those parts are. FF000000 00000F00 00000000 (stream request? after it streams begins in the third connection)

The second one is used for controlling commands and the third one is used for video stream.īy watching the communication and content of individual packets I was able to reconstruct the protocol structure. I realized that there are three separate connections being made! The first one just starts the communication and is idle. I started tcpdump and started looking at the data transmitting between the client and the server. I found out that there is also a native windows client so I downloaded it and it worked. All it had was an ActiveX viewer for Internet Explorer. I wanted to watch video stream of some old Nadatel? H-0410L 4 Channel DVR device on GNU/Linux. Just a quick report of me trying to find out how DVR sends video data to the viewer over the network.
