I believe you are looking for the "setup_mode" option.? Also specify the
log level at INF or higher to see the threshold values.

Hello to all,
If I allow myself to write here it is to have your ideas and feedback on
motion. I've been using it for several months now but I can't get the
desired result.
I have installed my alarm system (outdoor cameras, indoor cameras, 433Mhz
infrared detectors, siren, backup power supply, GSM shield and so on).
I would like to have the most functional system possible. It is not
conceivable to trigger the siren several times during the night for false
positives ! But on the other hand, this siren must be triggered
automatically during an intrusion. I can't keep my phone on all night to
check what's going on.
Today, in this alarm system I use among others a raspberry pi 3b+ with
motion (for the 4 outdoor cameras). However I have some false positives
that I can't avoid: mosquitoes that spend the night very close, water drops
at night when it rains etc.. At night when it rains I can reach up to 200
false positives. During the day, between 0 and 2 false positives. With so
little reliability, I even managed to turn off the outside cameras
finally...
Here are the images of some false detections.

By varying the different parameters I can't get a correct system. I set a
reasonable threshold (low enough to detect a human movement and high enough
not to constantly have false positives). But a spider passing in front of
the camera is finally impossible not to detect with the threshold (even
with the threshold_maximum) ...
I also activated the smart filter. It allows to avoid the movements of
grasses, trees and so on.
I think it's mandatory to add a human shape detection algorithm, don't you?
If so, do you know any that have a reasonable execution time? Indeed, all
the ones I tried take more than 30 sec to identify a human on a single
image! (Obvious given the CPU of a raspberry). And does a USB dungle really
worth it?
On the other hand, taking a step back, I find that very few home security
companies offer outdoor cameras. Or they are cameras you have to install
yourself and therefore the feedback seems disappointing. Maybe that's a
sign? Maybe we should only consider filming with outdoor cameras in order
to have different angles in case of indoor intrusions (identified by
infrared sensors which are more reliable)?
What do you think about this?
How do you do it?
Thank you in advance for your ideas/feedback.
