Arlo Video Doorbell 2K (2nd Gen) Wireless or Wired - 1-Cam | 2K HDR head-to-toe video; Front door security; Package & person detection; Night vision, 2-way audio; 1-mo Secure plan incl.

The Arlo Video Doorbell 2K (2nd Gen) delivers 2K HDR video with a 180° diagonal field of view that captures visitors head-to-toe and packages at doorstep level in the same frame. The latest generation improves on the original's video processing and motion detection accuracy.

Works either wired to existing doorbell wiring for continuous power or battery-powered for installation flexibility — a dual-mode option that works in homes with and without existing doorbell infrastructure. Arlo's AI motion detection distinguishes people, packages, vehicles, and animals for relevant alerts.

Full Arlo feature access requires an Arlo Secure subscription — the free tier provides basic functionality but AI smart alerts and extended cloud storage need a paid plan. Factor ongoing subscription cost into the total price comparison. The most versatile video doorbell for homeowners who want 2K head-to-toe coverage with the flexibility to install wired or wireless depending on their door setup.
