Spotlight Cam Wired - always on

Hi, I have "Spotlight Cam Wired" which is literally always on after dusk. I have all the settings dialled back as much as is possible and yet it comes on if a fly sneezes near it. I have sat in my car on the street and watched it come on for zero reasons. I just disabled all motion detection to see if that helps, but it's the same. In fact as I'm typing I had to switch it off via the web portal. Settings I have changed Motion detection - off Motion warning - off Motion zone - tiny, in fact its just in front of the door. I will attach some screenshots. Ah looks like I can't, so here is a link to a OneDrive folder with a handful of pics in it. https://onedrive.live.com/?authkey=%21AHjGGbdr9c5pO8Q&id=741F03E7BF7A5C1F%21399684&cid=741F03E7BF7A5C1FAs you can see my front door is near the road, but I have the motion zone defined as a tiny little area. My neighbour tells me the light is on pretty much all night. argh!!! Can anyone advise please? Thanks
