The ADC-VDB770, Alarm.com's next-generation video doorbell camera and the latest installment in the Design Studio Series product line, has an expansive 150° vertical Field of View (FOV), allowing you to monitor the entire doorway area. Two-Way Audio and full portrait viewing in the app make it easier than ever to see a speak with visitors. Plus, the ADC-VDB770 uses video analytics to minimize false-positive motion detection and to enable rapid detection of people, so you receive alerts even if visitors don't ring the bell.
