Monitor your home, family, pets, or indoor spaces with the YI Dome Guard 2K indoor security camera. It combines clear 3MP 2304 × 1296 video, smart AI detection (human, motion, and sound), remote pan-and-tilt control, two-way audio, enhanced infrared night vision, dual connectivity (Wi-Fi + RJ45 Ethernet), and flexible local or cloud recording — all controllable via the YI Home app and compatible with Amazon Alexa and Google Assistant.

What Is the YI Dome Guard 2K?

The YI Dome Guard 2K is a 360° pan-and-tilt indoor security camera designed for home monitoring, pet watching, and baby care. It uses AI-powered detection to distinguish between people, vehicles, and animals, reducing false alerts from non-relevant movement. Dual connectivity (2.4 GHz Wi-Fi and wired RJ45 Ethernet) ensures a stable connection even in areas with weak wireless signal. It supports 24/7 continuous recording to a microSD card or optional YI Cloud storage.

Clear 2K 3MP Video

See important details more clearly with up to 2304 × 1296 resolution (3 megapixels), whether you are checking a room during the day or viewing activity at night. The 2K resolution provides noticeably sharper imagery compared to standard 1080p cameras, making it easier to identify faces and read details at a distance.

Wide Pan-and-Tilt Coverage

Use the YI Home app to remotely control the camera across a 355° horizontal range and an 84° vertical range for broad coverage of indoor spaces. The motorized mechanism includes position memory, returning to its preset angle after power interruptions.

Smart AI Detection and Real-Time Alerts

The camera supports multiple detection modes:

• Human detection — identifies people and sends targeted alerts
• Motion detection — detects general movement in the frame
• Motion tracking — automatically rotates to follow a moving subject
• Sound detection — alerts when audio events occur (e.g. baby crying, glass breaking)

With YI Cloud subscription, advanced AI can distinguish between people, vehicles, and animals with higher precision, significantly reducing false alarms.

Enhanced Infrared Night Vision

The camera automatically activates enhanced infrared night vision in low-light conditions, providing clearer and brighter images compared to standard IR night vision. This allows around-the-clock monitoring without manual switching.

Two-Way Audio

A built-in microphone and speaker let you listen and speak through the app in real time. Talk to family members, check on pets, instruct delivery staff, or issue verbal warnings — all from your smartphone.

Dual Connectivity: Wi-Fi + Wired Ethernet

Connect the camera via 2.4 GHz Wi-Fi for flexible placement, or use the built-in RJ45 Ethernet port for a more stable wired connection. The wired option is recommended for locations with weak or congested Wi-Fi, or for users who require maximum reliability for 24/7 continuous recording.

Flexible Recording — Local, Cloud, or 24/7 Continuous

Save recordings locally to a compatible microSD card or use optional YI Cloud services. The camera supports 24/7 continuous recording when powered and connected, ensuring no events are missed. Cloud service availability, features, and subscription terms may vary by region.

Voice Assistant & App Control

View and manage the camera through the YI Home app on iOS and Android. The camera is also compatible with Amazon Alexa and Google Assistant for convenient voice-assisted viewing — say "Alexa, show me the living room" or "Hey Google, show the nursery camera" on compatible smart displays.

Versatile Mounting Options

The camera comes with a mounting base and a universal screw thread, offering multiple installation options: place it on a flat surface (desk, shelf, table), mount it on a wall, or attach it to a ceiling. Designed for indoor use only.
