Video Quality & Field of View
One of the biggest advantages of this doorbell is its 2K resolution (1944 × 1944). Compared to standard 1080p doorbells, this provides noticeably clearer footage, making it easier to recognize faces, read labels on packages, and see fine details.
The 180° diagonal field of view offers a full head-to-toe image of visitors and a clear view of packages left at your door. This wide angle reduces blind spots and improves overall front-door coverage.
Night Vision & Motion Detection
The Arlo Video Doorbell is equipped with infrared night vision, allowing you to see what’s happening at your door even in complete darkness.
Its motion detection system sends real-time alerts to your phone when movement is detected. With an optional Arlo Secure subscription, you can unlock advanced detection features like:
Person detection
Vehicle detection
Package alerts
This makes it especially useful for preventing package theft and monitoring unexpected activity.

Talking to delivery drivers
Greeting guests when you’re away
Warning suspicious visitors
The built-in siren adds an extra layer of security and can be activated remotely to help deter unwanted activity.
Smart Features & App Experience
The doorbell connects to your home Wi-Fi and is managed through the Arlo mobile app, which allows you to:
Watch live video
Review recorded clips
