The Google Nest Hello (NC5100EF) is a wired video doorbell offering 24/7 continuous recording, HD video with HDR, and person/package detection. It provides a 4:3 aspect ratio for viewing visitors head-to-toe and requires a 16-24VAC, 10VA transformer and a wired chime for installation. Key features include intelligent alerts via the Nest app, though some, such as familiar face detection, require a Nest Aware subscription.
