UK Camera recommendation needed

So I’m thinking about getting ST and trying to suss out the additional kit I need and even after loads of research I can’t find the answers to what I am after so appealing to the forum to assist.

I am after a camera that can

  1. Link to ST
  2. Available in UK
  3. Send images of events to personal cloud (Dropbox, Microsoft Drive etc) rather than having to have a paid for subscription.
  4. The standard stuff like motion detect to trigger recording and IR.

Haven’t managed to find anything yet; stuff that’s talked about on forums may have this but would be good to confirm.

Thanks in advance
