Modern buildings often come with doorbells that have cameras and voice support. There are apps for iPad/iPhone which would ring the device when someone rings the doorbell. Tapping the notification would open the app and establish a voice/video link to the doorbell system.
In order for this to work, some connection channel needs to be kept alive all the time. Upon certain data packages, the device needs to ring. |
