Argus Eco - How does PIR sentivity works?

hug com

Hi

I'm trying to set my new argus eco cameras on the IOS App.

There are 2 settings for PIR sensitivity level:
- reduce fake alarms (I don't know exactly how it is labelled in English since my app is in French) : on or off
- sensitivity level : between 1 and 100

I'm especially wondering about the first option. What is the impact on the algorythm when it's on?
To reduce fake alarms, mainly due to things moving with the wind, should I rather set the 'reduce fake alarms' option or reduce sensitivity level?

Thanks in advance for your help

It's better to turn on the reduce fake alarms.
Then, the camera will automatically skip some fake alarm by default.
Thank you and have a nice day.
