Video Doorbells — Datasheet

Overview

Overview

Video Doorbells turn your front door into a screened intercom — HD camera, big chime button, 2-way talk, package detection and a rolling pre-roll buffer that catches the seconds before the bell is pressed.

Designed for households that miss deliveries, get unexpected visitors, or simply want to know who is on the porch before opening the door. Available wired (uses your existing chime wires) or battery-powered (drill four holes, charge every 3–6 months), with a real indoor chime, optional Echo Show / TV banner, and an audit-quality cloud clip for every event.

• HD video 1080p / 1536p / 2K with wide head-to-toe field of view
• Pre-roll buffer — the last 4 seconds before the press are captured too
• Package detection — alerts when a parcel is dropped and when it disappears
• 2-way talk + quick replies — answer like a phone call, or tap a canned response

How It Works

The diagram above shows one ring cycle — porch motion to phone in 6 seconds. Hover any module to see live status.

1. The doorbell sits at the door — HD camera up top, motion PIR, big chime button, mic and speaker. Runs on wired transformer (8–24 V AC), battery, or solar.
2. View & detect watches the porch continuously, captures a 4-second pre-roll into a rolling buffer, classifies people / packages / vehicles, and ignores leaves, pets and shadows.
3. Chime & cloud rings the in-home chime, flashes a banner on Echo Show / Fire TV / Google Hub, and uploads the encrypted clip to the cloud timeline (7 / 14 / 30 / 60 day plans).
4. Answer from phone — every paired phone rings at once. Answer with full-duplex 2-way audio, send a quick reply ("Leave it at the door"), or dismiss.
