One thing I'd like to see is offloading object detection to the camera. Many cameras now include event detection and I'd like to use the on-board dedicated hardware in each camera rather than trying to do it on a local GPU for each of my data streams.
There is now the event trigger in the API where you can tell frigate something has happend like a doorbell press. I'm still not clear if this just acts like a regular motion event where it'll do person detection ect after. if so I was thinking of setting up a mm-microwave sensor at my front door because the shadows constantly trigger motion events.
