I use blue iris to do this. The bonus is that I don't have to go through MQTT. While BI does have the ability to go through an MQTT broker I just have it communicate directly with the hub.
I did think about running it in a docker, but I have 10 cameras on it now and that would kill my server. So I repurposed an old i5 to handle it all. It stores up to 3 weeks of 24/7 recording and events.
You might have to look into doing something like that with Frigate too...as you add more cameras the cpu requirements go up. Its a rabbit hole. lol
Here's a post with some of the things I do with BI.
