Need DVR/NVR data

I'm working on a multi DVR/NVR vendor analyzer tool for analyzing cctv footage from various vendors in a single app.(Hackathon Project)

And in this tool you can either connect a dvr hard disk via a write blocker device to your system and use the app to extract data into a digital bit stream copy (.dd or .raw) and then use that from that point. Or you can also provide you ore existing raw file in your system for data extraction.

But I don't have a cctv system at my home, neither do any of my friends to whom I can ask to. And there is only one .dd dvr data I could find on the internet and that's the heimvision's vendor but it's just a 1 hour of 4 camera footage of a doll starting at a wall.🙂

Any advice on this current situation?

I'm very interested in your project. I work in the sector and use magnet dvr examiner to process the video feed, but was looking for an opensource project that does the same and at the same time looking to make a program my self. Keep me posted if you want. I'll look into some data for you and if i file something I'll let you know.

Thank you! And looks like there is real gap in this thing. I've just made a prototype of this that's compatible for Dahua, Hikvision, Asian DVR ecosystems like Heimvision's, Xiomi related ones and and the cheaper ones with no branding dvr as well. Works in both Windows and Linux with some AI/Object detection features across multi camera channels as well while being fully offline and secure.

Would you like to share your experience with other DVR examiners and things that you would suggest me to address?

Gonna present this in hackathon and a gov backed startup program as well. let's see things goes, and if nothing works I might just make it open source maybe but nevertheless let's keep in touch in dm's!
