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

Full Smart Doorbells comparison in 2026

Updated August 2026
Data from Amazon and official Arlo and Eufy sites.
2026 verdict
The Arlo Video Doorbell 2K (2nd gen) edges this 2K video doorbell comparison on price, integrations and alerts, coming in cheaper while adding IFTTT alongside the Google, Alexa and Home Assistant support both share, plus a broader smart-alert menu (people, packages, vehicles and animals) and included motion zones the Eufy Video Doorbell C31 (with Battery Pack) lacks. The Eufy is the higher-rated unit and its trump card is storage: it records locally to microSD or a Eufy HomeBase with no subscription, keeps offline and powerless event history, and adds automatic replies, whereas the Arlo has no local storage and locks cloud video, smart alerts and even motion zones behind an Arlo Secure plan. Both are 2K, 2.4GHz-only, wire-or-battery, and skip HomeKit and Matter. Choose the Arlo Video Doorbell 2K (2nd gen) for its wider platform reach, object recognition and 180-degree head-to-toe view if you accept the subscription; choose the Eufy Video Doorbell C31 (with Battery Pack) to avoid monthly fees with local recording.

Frequently Asked Questions

Which is better overall, the Arlo Video Doorbell 2K (2nd gen) or the 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.

What separates these two the most?

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.

Which doorbell has better smart alerts?

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.

Do either avoid a subscription?

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.

Who should buy the Arlo Video Doorbell 2K (2nd gen)?

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.

Who should buy the Eufy Video Doorbell C31 (with Battery Pack)?

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.
