Dingdong is an intelligent retrofit video doorbell for single family homes. The video doorbell offers users a high level of comfort and security. Via the connection to the smartphone, a video and audio transmission can be established at any time to persons who are at the front door. The integrated motion detector or the activation of the bell button sends a report to the smartphones of the residents. On the display of the bell button any messages can be displayed, e.g. „in absence please leave packages with neighbor XYZ“. can be displayed. The housing of the doorbell is characterized by an inwardly offset camera recess that ensures a clear view with the widest possible viewing angle even in weather conditions.
