Arlo Video Doorbell 2K (2nd gen) vs Eufy Video Doorbell C31 (with Battery Pack)

The Arlo Video Doorbell 2K (2nd gen) wins overall on price, wider integrations and richer alerts (people, packages, vehicles and animals). The Eufy Video Doorbell C31 (with Battery Pack) is better rated and records locally with no fee, so the right pick depends on whether you prefer object recognition or subscription-free storage.

How they handle storage. The Eufy Video Doorbell C31 (with Battery Pack) records locally to microSD or a Eufy HomeBase with no monthly fee, while the Arlo Video Doorbell 2K (2nd gen) has no local storage and needs an Arlo Secure subscription for cloud video, smart alerts and motion zones.

The Arlo Video Doorbell 2K (2nd gen) supports more alert types, adding package, vehicle and animal detection on top of people, which is why it wins the alerts category, though those require Arlo Secure. The Eufy detects people and motion locally without a plan but does not flag packages, vehicles or animals.

Only the Eufy. The Eufy Video Doorbell C31 (with Battery Pack) stores footage on microSD or a Eufy HomeBase with no monthly fee and even keeps offline recordings. The Arlo Video Doorbell 2K (2nd gen) has no microSD option, so viewing history and running smart alerts require an Arlo Secure plan.

Buyers who want a sharp 2K 180-degree head-to-toe view, wider integrations including IFTTT, and accurate person, package, vehicle and animal recognition, and who accept paying for Arlo Secure. It is the more feature-rich doorbell if you live with the fees.

Owners who want 2K video with no monthly subscription, especially those with or planning a Eufy HomeBase. The bundled spare battery, local recording and automatic replies make it a strong fee-free option, and it carries a higher owner rating.
