One of the mostimportant features that supremacy the IP intercom system from other intercomtechnologies is that it provides 2-way voice and video calls.

When the guestat the door presses the push and calls, the camera of the front doorphone sendsthe view to your monitor. This is 1-way video transmission. Also indoormonitors with camera can send the video it to the outdoor unit during call.Thus, two-way audio and video communication is ensured. Likewise, when a callcomes from the doorbell to the smartplus app, the video of the camera of thedoorphone can go to the smartplus app and the video of the camera of the mobilephone to the doorphone screen.

2-waycommunication is only supported on R29 and X915 devices.

In order toenable 2-way communication, it is necessary to make the settings from thedoorphones web interface as shown in the picture.

Remember,although 2-way video calls are a result of advanced technology, the consent ofintercom users is also important in this regard. Consider the preferences ofthe users in your project.
