eufy C120 - Compact 2K Indoor Security Camera with Advanced AI Motion Detection

The eufy C120 is a compact security camera that delivers professional-grade monitoring for every room in your home. At just 2.24 × 2.24 × 4.11 inches and 3.68 ounces, this discreet camera fits seamlessly into any space-on a bookshelf, nightstand, or mounted unobtrusively to a wall. Despite its tiny footprint, the eufy C120 packs powerful features including razor-sharp 2K video resolution with 24/7 continuous recording capability.

The eufy security app gives you complete control from anywhere. Receive push mobile alerts instantly when motion or sound is detected, with the on-device AI sorting real motion from background bustle. You'll only get meaningful alerts when they matter most. The intelligent filtering eliminates false alarms from moving curtains, ceiling fans, or passing shadows-a feature that sets the C120 apart from basic motion cameras.

Unlike cameras that send everything to the cloud, the eufy C120 processes video intelligence locally on the device itself. This approach keeps your clips private, maintains lightning-fast response times, and works seamlessly even during temporary internet outages.

Smart Local Processing: This model uses smart motion detection processed locally. Your clips stay private and latency stays low-no cloud delays.

Two-Way Audio & Night Vision: Talk to a courier, calm a pet, or remind teens to start homework from anywhere. Infrared LEDs extend crisp night vision up to 32 ft, so corridors and nurseries stay visible after dark.

Why Compact 2K Monitoring Matters

Superior Optics and Wide Coverage

The eufy C120 features a bright sensor paired with a 125-degree wide-angle lens that delivers wall-to-wall coverage throughout most indoor spaces. This expansive field of view means you need fewer cameras to monitor the same area compared to standard security cameras with narrower lenses. The camera delivers exceptional 2K clarity indoors (1920×1200 resolution), capturing fine details like facial features and license plates from across the room. When connected to HomeKit, resolution adjusts to 1080p to accommodate HomeKit's processing requirements. The advanced wide dynamic range (WDR) technology ensures balanced exposure and vivid color reproduction even in challenging lighting conditions-whether you're monitoring a bright window area and dark corner simultaneously, the eufy C120 preserves detail in both.

Flexible Storage: Your Data, Your Choice

The eufy C120 doesn't lock you into proprietary cloud services. Video clips save directly to local microSD cards (up to 128GB capacity), connect to a Network Attached Storage (NAS) device via RTSP protocol, or optionally backup to Eufy's secure cloud storage. This flexibility means you maintain complete control over your footage-no subscription requirements, no recurring fees, no vendor lock-in. Local storage ensures your most important security footage remains accessible even if internet service temporarily goes down. Many users prefer the microSD approach for maximum privacy and total autonomy over their security infrastructure.

Privacy Mode: Control When You're Recorded

Sometimes you need complete recording privacy. Activate privacy mode to pause recording and disable the camera instantly. This feature is essential for family movie nights, personal moments, or when guests visit. The physical LED on the camera turns dark when privacy mode activates, providing visible confirmation that recording has stopped. Combine privacy mode with geofencing through the eufy security app to automatically enable privacy mode when you arrive home and disable it when you leave-creating a seamless, hands-off experience.

Advanced AI and Smart Detection

The eufy C120 uses sophisticated on-device artificial intelligence to differentiate between people, pets, and objects. This intelligent filtering dramatically reduces false alarms from common household movements, allowing you to focus on genuine security events. Instant noise detection flags critical sounds like crying babies or breaking glass, triggering alerts so you respond immediately to important moments.

Voice Assistant Integration: Control the eufy C120 through your preferred voice ecosystem. Alexa integration lets you ask "Alexa, show me the nursery" to view live video on an Echo Show. Google Assistant users can cast footage to a Google Nest Hub with a simple voice command. HomeKit support integrates the camera into Apple's ecosystem for end-to-end encrypted recording through HomeKit Secure Video.

Custom Activity Zones: Define specific detection areas within your camera's field of view. Ignore hallway traffic, ceiling-fan motion, or outdoor movement while staying alert to important indoor areas. This granular control prevents alert fatigue and ensures notifications focus on what matters.

Effortless Installation: Setup takes just minutes. Scan the QR code provided with the camera to add it to the eufy security app, complete Wi-Fi pairing, and you're online in under three minutes-no complex configuration required.

Multi-Layer Security: Secure end-to-end encryption shields every frame from unauthorized access. Local processing on the device means sensitive footage never leaves your home unless you explicitly choose cloud backup.

Instant Mobile Alerts: Receive notifications within seconds of detecting suspicious motion. The eufy security app delivers immediate push alerts to your phone, tablet, or smartwatch so you stay informed in real-time regardless of location.

Dual Storage Options: Choose between microSD card (up to 128GB) for local-only storage, NAS connectivity via RTSP protocol for network storage, or Eufy's secure cloud backup service. This flexibility ensures you never lose critical footage and maintain complete control over your data.

Each capability meshes to create a smarter safety net: AI can flag barking, mute nuisance alerts, and still log the moment a delivery arrives.

Effortless Setup and Smart Integration

The eufy app walks you through Wi-Fi pairing, lens calibration, and activity zones in minutes. No proprietary hub is required, yet HomeBase 3 support future-proofs your system with facial recognition upgrades. Shout "Alexa, show me the nursery" for an instant feed on an Echo Show, or cast live video to compatible smart displays with one command. HomePod owners enjoy end-to-end encrypted storage through HomeKit Secure Video.

With activity zones, you can customize detection areas to avoid unwanted triggers, ensuring alerts only for important events.

Keeping Data Private and Secure

When privacy mode toggles, the status LED goes dark and recording halts; geofencing can trigger this automatically as you walk through the door. Firmware carrying CE, FCC, and RoHS marks underscores commitment to safety and sustainability. Users can store footage locally with a microSD card up to 128GB, or connect to cloud storage if preferred. Encryption ensures your clips stay private.

Real-World Peace of Mind

Families, renters, and pet owners laud the C120’s reliability. Amazon buyers give it 4.7 stars across more than 12 000 reviews, praising snappy alerts and sturdy build quality. Priced at an affordable $42.99, the C120 is often praised for offering premium features without the need for ongoing subscriptions.

Digital Camera World notes that the wider lens can cover an entire playroom with a single unit, reducing blind spots and hardware costs.

Industry writers highlight the retro-mini aesthetic that fades neatly into décor.

Everyday Use Cases

Parents: Use the camera as a baby monitor. Noise detection pairs audio pings with real-time visuals so you respond before small sounds escalate.

Pet Lovers: Schedule alerts only during work hours. Keep tabs on playful kittens without overnight pings.

Remote Workers: Point the lens at a window to confirm deliveries and deter porch pirates.

Renters: Take the microSD card and your footage when you move-total portability.

Smart Home Integration: Combine the C120 with smart lighting, automated routines, or motion-triggered alerts for more power. Sync with voice assistants to trigger lights when motion is detected. Automate recording schedules to match your daily routines. These integrations create a home environment that feels both intelligent and responsive without manual adjustments.

Whether you want extra awareness during vacations or snapshots of activity while you work, the C120 adapts smoothly to your changing needs.
