For now the package arrived perfectly super fast thanks seller thanks to Aliexpress now the only thing left is to try it and I will make another comment on its operation

It is effective although the app is very poor.
But for the price

Is the only one that looks like a normal peephole and has a pretty good image quality, even at night and you don’t see any red led on. I have to see how long the battery lasts. It pairs very easily and the vision of the mobile is very good. I ‘ve got to do more tests. I will ask for another door, I liked it a lot.

I am satisfied with the purchase. Full compliance with the description.Very good display quality, very readable, simple WiFi connection configuration

The part that enters the wall is a little wider than the existing switch, so the cement wall has been cut a little, but other than that, it is very difficult well installed without Wow, it works very well too. It was nice to come faster than I thought.
