TP-Link Tapo TD21 — See Everything. Miss Nothing. No Subscription Required.

The TP-Link Tapo TD21 is a wireless smart video doorbell that delivers premium home security without the premium price — or a monthly subscription. 2K crystal-clear video, head-to-toe coverage, AI-powered person detection, two-way audio, and weatherproof construction, all in a sleek White design that installs in minutes. Available in a 1-Pack or 2-Pack to cover every entry point.

2K Video — Every Detail, Day or Night

A 2K (2560 × 1440) HD camera with a wide 160° field of view gives you a complete head-to-toe perspective of your front door — faces, packages, and the full porch area, all captured in stunning clarity. Real-time video streams directly to your smartphone via the Tapo app (iOS & Android), so you always know what’s happening at your door, wherever you are.

Smart AI Detection — Fewer False Alerts. More Peace of Mind.

Built-in Smart AI person detection distinguishes between people and other motion sources — so you get notified when it matters, not when a car drives by or a leaf falls. Customizable motion sensitivity settings let you fine-tune alerts to match your environment.

Two-Way Audio — Talk to Anyone at Your Door

A built-in speaker and microphone enable clear, real-time two-way audio communication directly from your phone. Answer the door for a delivery, greet a guest, or deter an unwanted visitor — all without leaving your couch or your office.

100% Wireless. Easy Installation.

The TD21 is battery-powered with a rechargeable battery — no wiring, no electrician, no hassle. Mount it anywhere with the included adjustable bracket and connect to your 2.4GHz Wi-Fi network in minutes using the Tapo app. Setup is straightforward enough for anyone.

IP65 Weatherproof — Built for Every Season

Rated IP65 weatherproof, the TD21 stands up to rain, snow, heat, and cold year-round. Whether it’s a summer downpour or a winter freeze, your doorbell keeps watching.
