Selfhosted
A place to share alternatives to popular online services that can be self-hosted without giving up privacy or locking you into a service you don't control.
Rules:
-
Be civil: we're here to support and learn from one another. Insults won't be tolerated. Flame wars are frowned upon.
-
No spam posting.
-
Posts have to be centered around self-hosting. There are other communities for discussing hardware or home computing. If it's not obvious why your post topic revolves around selfhosting, please include details to make it clear.
-
Don't duplicate the full text of your blog or github here. Just post the link for folks to click.
-
Submission headline should match the article title (don’t cherry-pick information from the title to fit your agenda).
-
No trolling.

That's a fair point. I haven't actually methodically gone through to see exactly how many I would need just yet. The numbers that I chose were somewhat just ballpark off the top of my head.
I am planning to give the camera server dedicated storage for the data. If I'm really feeling like splurging on it, I may look into getting WD Purple drives, or the like.
I'm not sure that I would need this very much. I'm mostly interested in a sort of ephemeral surveilance system; I only really need to store, at most, a few days, and then rewrite over it all.
Would you say that 15FPS is a good framerate for surveilance? Or could one get away with even less to lessen the resource requirements?
What tweaking do you generally need to do for the camera server?
If doing CPU-based motion analysis, you could use a lower quality stream (if available from the cameras to avoid transcoding load) for motion detection, then use that to trigger recording on a higher quality stream.
Brilliant idea! Thank you for the suggestion!
Whyd do you specifically mention CPU-based motion analysis? Does this idea not work with the Google Coral TPU, for example?
I'm using ZoneMinder on my end with more rudimentary motion detection, hence CPU detection. (My current hardware is pre-IOMMU on the mobo, so no pci passthrough for me...)
That said, if you have hardware that can handle X (via CPU, GPU, TPU, etc), then you gotta decide how you want to spend that. Whether resources are spent more in analysis fps or evaluating higher detail frames is up to what you need.
