@Aussie_Pete totally agree. I've the same

problems as everyone in this topic. 
 

Maybe it's a good idea to split up the issue? I mean if an insect crosses the window or camera lens (mine is behind a window at the moment) I can imagine this is harder to filter it out than raindrops. Leaves falling from trees or blown up by the wind are a third kind of movement. 
 

So a couple of questions to tp_link 😃 

can you develop a fix solving movement issues with rain?

same question with snow?

same question with leaves?

same question with flying insects at night?

same question with walking by insects?

For me these issues are also sorted in priority. Maybe the flying insects should be higher, but because I'm still behind glass I have other issues with the reflection of infrared so I can't see anything at night at the moment. 

While you are developing  I can go on installing camera 2 and 3 😃 

Thanks a lot!! 

  @PeterSwe Same issue here. Incredibily frustrating. Thinking of returning them
