Presets and Detection Sensitivity

Hello. Im trying to get the detection sensitivity just right but at the moment using the standard presets I'm either getting too much motion detection or non at all. I've tried high, medium and low but all produce undesired results. If I start on the low preset and alter a setting upwards (fine tune) hope this would work. But I'm not quite sure which value to alter..
Any help appreciated.
Thanks.

Motion detecting can be a bit of a rabbit hole.
I typically set to best,highest sensitivity, change to percentage, then lower number to about 3 (percent).
You can tune it by enabling zm_analysis images in options (if you want). You can also just watch events live, and see if they are flagged as alarms or not, then adjust numbers as needed.
I also use hardware motion detectors. Those can be quite reliable, at the added cost of initial setup.
Here's one tip: Set a min, then set a max. The max limit (i.e. screen flashes due to IR turn on) may help keep some alerts down.

Most of the zone presets were designed for analog capture cams around 320x200. They don't work well for 1080p cams etc.
I typically start by setting the units to pixels and the minimums to 1000 pixels or less.
Expect improvements here in 1.36

Start with Best, High sensitivity and tune it down. For me better works with smaller zones. Define zones only where the area of interest is.
