There is a 500 character limitation per message. You can do multiple messages. Aside from the chat, there is also phone support, and email: https://www.tp-link.com/us/support/contact-technical-support/#Hotline-Support

The motion detection is by pixel change rather then the object so a shadow or person would not matter. 

Please provide a screenshot of the settings you have for your cameras, mainly the privacy and sensativity settings.

@Tony Check again. When I entered text into the form and tried to submit it, the error message stated a 200 character limit. 

@Tony I did wind up on the phone, did my best to interact with the CSR (strong accents are a problem for me), and did submit screenshots and video. Yet your explanation about pixel changes? It doesn't hold up.

Before trying the Kasa Cams, I used Arlo Pro for several years. Never once did I get recordings of leaf shadows, as I do with Kasa. I did get recordings of actual branches moving in the wind, but not just the shadows.

Is their technology visually "smarter" than yours? I don't know. But I do know that the number of pointless recordings was a fraction of Kasa's, and Arlo, at least, permits viewing the recordings sequentially, selecting multiple recordings, and deleting them all at once. Every Kasa recording has to be viewed and deleted individually. The wasted time to do that is substantial... and annoying.
