Eufy 2C Pro: night recording

I bought an Eufy 2C pro kit. While daytime detection/recording is as expected (detection at 25 feets which triggers recording) night behaviour is weird. Detection is still at 25 feets (confirmed by IR leds activity) but recording is trigged only at half the distance, like 12 or 13 feets. It’s consistant and never changes whatever options are selected in the app.
Do you notice the same behaviour?

I found the root cause: AI. AI statistics show that events are quite agressively filtered. Even if I’m detected AI considers it’s a false postive. Then no recording is trigged. It’s weird. Maybe an issue with the latest software?
