Product not as advertised

Hey people so i wanna spill my 2 cents.

I bought a battery doorbell with homebase after some research.
Eufy seemed the best with local storage app and everything, even that you could link it to a network storage device or expand the memory.
After a few days i descided to buy an extra camera for the back of my house aswell.
And to my suprise this has rtsp ???
Why not for the doorcam and base as advertised.
I cannot return the product in my country since i used them, and i feel very disappointed.
