Stick up cam People v Motion issue

Hi, I Installed a floodlight cam to the rear of my property and a stick up cam to the side yesterday. I have an issue, the stick up cam tells me almost constantly that there is a “person at the side” There has YET to be a person there. So far it has detected: a bit of fence liner flapping in wind. Numerous cats. A squirrel. Some leaves. A tree branch bobbing in the wind. Nothing. I have amended the activation zone to avoid the tree branch, i have stapled the fence liner, however I can do little about the neighbourhood cats & wildlife. I have turned sensitivity down to minimum and put smart notifications on for “people only” Any help is appreciated otherwise its gonna have to come down & be returned for something else. Cheers all!
