eufy Security, Video Doorbell S220 (Battery-Powered) Kit, Security Camera - 2K Resolution, 180-Day Battery Life, Encrypted Local Storage, No Monthly Fees, Built-in Storage, Motion Only Alert

The Eufy Security Video Doorbell S220 is a smart, battery-powered video doorbell kit designed for reliable home security without the burden of monthly fees. It offers a good balance of video clarity, long battery life, and local storage, making it a strong pick for those who want to monitor their front door securely and privately.

Key Features:

High-Resolution Video

Records in 2K resolution (2560 × 1920), giving you very clear and detailed video.

Has Wide Dynamic Range (WDR) to help deal with challenging lighting conditions (e.g., bright backlight). Uses an expanded 4:3 aspect ratio that helps you see a more complete “head-to-toe” view of people approaching the door.Power Options & Battery Life

Comes with a built-in rechargeable battery that can last up to 180 days per charge under typical usage.

Alternatively, you can hard-wire it to existing doorbell wiring (8–24 V) if you want always-on power.

Local & Secure Storage

Video is stored locally on a HomeBase unit (included in the kit) rather than relying on cloud storage.

HomeBase includes 16GB of built-in storage, which can hold your recorded video events.

All video data is encrypted using AES-128 (or AES-256, per region) for security in transit and at rest.

Because everything is stored locally, there are no monthly subscription fees for basic video recording and storage.

Smart Motion / Alert Detection

Uses on-device AI to detect human presence, reducing false alerts from non-human motion.

You can create custom activity zones in the app to limit motion detection to certain areas (e.g., your walkway) to reduce unnecessary alerts.

Supports “motion-only” alerts so you’re only notified when meaningful motion is detected (depending on setup).

Two-Way Audio

Built-in microphone and speaker let you talk to visitors through the doorbell using the Eufy Security app.

You can also use pre-recorded responses (e.g., “Leave the package by the door”) to respond quickly when you’re away. Durability & Weather Resistance

Rated IP65, meaning it’s weatherproof and can handle a wide range of outdoor conditions (temperatures from –20 °C to +50 °C).

Designed for easy installation — you can mount it yourself, and either snap it into place or connect wires if you choose to hard-wire it.

Smart Home Integration

Works with  and Google Assistant, so you can ask your voice assistant to show the doorbell camera or use it as a chime.

You can use the HomeBase speaker as a doorbell chime, or use a compatible Echo device for that role.

Advantages / Pros

Privacy-first design: Local storage + encryption = more control over your video data.

No recurring costs: Because storage is local, you avoid cloud-storage subscription fees.

Flexible power: Use battery for wireless installation, or wire it in for constant power.

Long battery life: 180-day battery claim means less frequent recharging (if usage is moderate).

Good image quality: 2K resolution + WDR allows for clear and useful video, even in tricky lighting.

Smart detection: AI-based detection helps reduce false alerts.

Rugged for outdoors: IP65 rating makes it suitable for outdoor installation.

Potential Drawbacks / Things to Consider

Storage limit: 16 GB in HomeBase will fill up over time depending on how many events you record; you might need to manage space.

Battery life varies: Real-world battery life depends heavily on how often motion is detected, how often it’s viewed, and other settings — users have reported less than the maximum in some cases.

Motion detection quirks: Some users report issues with motion detection sensitivity or missed events.App reliability: As with many home security systems, some users mention intermittent issues with viewing events or connecting the app.

Storage expansion: Depending on the HomeBase model, upgrading storage may require additional hardware (e.g., a hard drive) if you want to keep a lot of clips.
