Finally, I have some time to tell the story.
Again, thanks a lot for all of your advice.
Since I live in Russia, the easiest way to get a Reolink camera was to order it from Aliexpress, but shipping would take some time (about 2 weeks) and I left on the 10th of July.
So on the 8th of July I went to a local security camera shop and the guy there sold me Imou Ranger 2 (I bought only 2 and thought to order some Reolink later, they are almost half the price). Apparently, Imou is a Dahua sub-company and Dahua cameras are quite popular and good enough. It has ONVIF support, but I was too lazy so I just used their own app (1-month free trial, 2USD/months later).
Here comes the problematic part. As I understood, I will have to get 2 Blue Iris licenses to be able to use remote access. Or I could use TeamViewer, etc. and have email notifications. Something similar is with iSpy/Agent DVR, but there I would have to pay a subscription fee. The problem is (as always) the price. Imou asks 20 USD if I want an annual subscription with 3 days cloud storage and Blue Iris is a bit over 83 USD (because I have to pay 20% taxes). So now I am thinking about what to use because on one hand, I don't trust Chinese servers, but on the other Blue Iris costs more (4 or 8 years (1 or 2 Blue Iris 5) for Imou to become as expensive as Blue Iris) and I would need a PC (currently I have a laptop, which I move back and forth with me) for it. I will dig for more information and write if I find something interesting.
