I bought this one from Amazon :
https://www.amazon.co.uk/gp/product/B07BVRMN75/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1
picture quality seems very good, mic works, I thought there were some delays with speech from my phone being relayed but i am not so sure now.
Cats don’t respond to my calling them but have discovered that if I make a whistling blowing sound it spooks them so i can see them react.
Setting it up can take a bit of time as it seems to think about taking the panoramic set of photos for some time before actually doing it.
but it seems a bit of a bargain and I am going to buy some more for all their other hiding spots…
