## What reviewers say

**Arlo Pro 5S 2K** — Two whitelisted testers (Tom's Guide and PCWorld/TechHive) hands-on-reviewed this exact model (VMC4060P). Both praise excellent 2K video in daytime and color night vision and accurate person/vehicle/animal detection with robust automation; both flag that an Arlo Secure subscription is required to unlock core features including cloud 2K recording, and that local storage needs a separate $100 Arlo Pro Smart Hub. They diverge on whether the high ongoing cost is worth it. (2 sourced reviews.)
