Blink Video Doorbell – Two-way audio

Video Doorbell helps you welcome visitors and keep an eye on your door while our wire-free Outdoor camera can be placed anywhere you need it. Together, they provide full home coverage with features like two-year battery life, two-way audio, 1080p HD day and infrared night video, custom alerts, privacy settings, and more.
See visitors day or night with HD video and talk to them any time using two-way audio through the free Blink Home Monitor app.
Choose to save and share clips in the cloud with a free 30-day trial of the Blink Subscription Plan or locally with the included Sync Module 2 and USB drive (sold separately).
Designed for every home, go wire-free or connect to doorbell wiring to also sound your existing in-home chime. Without wiring, you can use your Blink Mini camera (sold separately) as an indoor plug-in chime.
Set up yourself in minutes with the two included AA lithium batteries (per device) then connect to wifi in the app.
Works with Alexa — access live view, two-way talk, receive motion and chime alerts, arm and disarm your doorbell, and more.
