I have this configuration. I have a desire to reduce the load on the processor that is engaged in detection. In this regard, I wanted to reduce the detection zone and set it in the config
garage_on_home1:
detect:
width: 800
height: 600
fps: 5

after that, I get a real-time image size of 800 by 600 pixels.
I don't really understand why the detection parameter affects the size of the camera display in live mode.

The name of the stream garage_on_home and the name of the camera garage_on_home1 do not match, so go2rtc is not used for live

[crazych1]

Thanks, it worked with live mode. But as I understood the parameters
detect:
width: 800
height: 600
fps: 5
affects the frame size transmitted to the detector. And at 800 x 600, small objects become indistinguishable. I thought this parameter was responsible for the maximum size of the detected object.

[NickM-27]

No, it has nothing to do with affecting the object filtering
