Your doorbell just got smarter! Bring your front door wherever you go with triple HD image quality and high fidelity two-way audio. Don't get up to tell that pesky sales person you're not interested, do it right from your couch using the EZVIZ app on your smartphone. Once the DB1 is rang, a video initiates, allowing you to see, hear, and talk to the person at your door. You can even control the doorbell with your voice via Google Assistant or Amazon Alexa. See who is ringing your DB1 from head to toe with its excellent 180 degree vertical field of view. Minimize false alarms by setting specific detection ranges appropriate for your individual doorway. The DB1 also uses thermal detection technology to help concentrate notifications on living visitors.
