Hi,

I'm trying out the picam720 plugin for a bigger resolution (Pi4, Bullseye 32bit, Pi Global Shutter Camera, 60fps), however, no cars get detected, I'm seeing this:

What does it mean and what do I need to tweak?

Thanks!

If I understand it correctly, the location of the detected box moved further away than 30 px, thus registering the event as Out, correct?

Zooming out solved it. I guess increasing the MO_MAX_X_DIFF_PX would also have helped?
