Event Recording Hit or Miss

Have the Cam-Pan and the Outdoor Cam. Recording of events is sporadic at best. The Cam-Pan will record wind blowing tree leaves across the street. But, not record a FEDEX truck crossing the detection zone. Same thing with the Outdoor Cam. No, rhyme or reason. I’ve looked through the forums here and all my settings are as recommended. Live stream is fine. Notifications work, when it does record. Varied sensitivity to no avail. Just seems like each camera records motion detected events when it wants. Cool down is NOT the issue. Events are hours apart. Sometimes the Pan-Cam will focus on the object in the detection zone, follow it. But, not record it.
Seems like many people have issues similar to this.
