I have a Pi3 and a 2TB purple drive that I want to use as an NVR, my main issue with most solutions is that they offer too much for my needs and what the pi can provide. Going beyond a raspberry pi 3 is not realistic, since right now I'm feeding it with 15W POE, tucked away on a difficult to find location in case someone breaks in.

The most common solutions like frigate and shinobi do transcoding by default or have advanced image recognition features. I do not require such things as a 1 or 2 week recording window is enough and all cameras are wired to a dedicated switch so bandwith is not an issue. My only requirements beyound that are playback (again, with no transcoding) and maybe external events, live viewing I've already taken care of so it's not a requirement.

One project I was able to find is https://github.com/marcus-j-davies/nvr-js, which is described by the author as a light weight version of shinobi, it's pretty much what I need but last commit was 2 years ago so I'm open to considering other options.

Do you know of any projects that fit this description? Were you able to turn frigate, shinobi or any other NVR into a get-and-store, read-and-send programs, no transcoding? If so, would you mind sharing how you did it?
