Dling is a smart video doorbell. Together with an associated app it allows for easy communication with visitors even when the user is not at home. The unit has a body recognition function and records any disturbances at the front door. In this case, it will immediately notify the user. Paired with a bell receiver, this ensures that Dling provides timely notice of visitors. The discreetly designed unit with rounded edges and low energy consumption will run for six months on only four AA batteries.
