Can you imagine how it probably smells?

Only downside to it. Ran it in a windows VM in Unraid for about 5 years.

I think BlueIris full retail copy is something like $50. You pay yearly for upgrades which is around $25. It’s gone through many major upgrades. They do have a trial you can grab to give it a shot.

I know you said Open Source but the ones I tried were not fabulous. I used BlueIris for about a decade. I recently depreciated that for a Ubiquity NVR and cameras. BlueIris works well if you have an Intel CPU with iGPU to do the decoding. BlueIris can record to network attached storage and if you follow online guidelines you can ensure CPU utilization isn’t through the roof.

Science is a liar sometimes
