A normal sound and all the rest are terrible. Good build quality though.
The internal screen does not screw onto its base. It hangs. The speaker on the front door cannot be heard. Overall, so-so

The electrician recommended it to me when I was renovating.
In my opinion, it is very mediocre. The image quality is like a mobile phone from 2004. The microphone can hardly be heard from the door speaker. The doorbell is not easily heard. I will not replace it due to the cost, but definitely if I had the choice, I would look at another one.
