No need to go outside and check to see who is visiting you.
With these features you can easily see who is there without leaving your unit.
The OBERON Outdoor 1-Unit Door Phone can be used to call 1 unit, such as an apartment or villa. It can be installed inside or outside. It will call the Oberon indoor monitor in each unit. The indoor unit will also forward calls to users’ smart phones, allowing you to answer your door from anywhere.
