You can configure call schedule templates to define when indoor stations and call centers can receive the call from door stations. After you configure the templates, you can add the templates for door stations so that they will distribute calls to indoor stations or call centers as configured in the schedule template. Finally, you can apply call schedule to devices, so devices such as indoor/door stations and call centers can execute commands from the platform. Besides, after adding indoor station to the system, you can link camera with the added indoor station to view the video of the related camera(s) on the indoor station. You can also link single person to indoor stations for calling residents. In addition, you can relate a doorbell with an indoor station. When the Call Management Center function of this doorbell is disabled, you can call the related indoor station by the doorbell.
