Tested on 10 meters distance home- gate, it works great.
It allows, hearing one of 16 proposed ringtones, know who reports to the portal, even if the person does not ring.
The device records an image when ringing. (Store up to 100 pictures).
The screen design; it can be wall mounted or placed on furniture. The downside is recharging of the outdoor unit that requires a decision.
This device seems to me good.
