Everything you need to start. No subscription required. The eufy Security 5-Piece Home Alarm Kit is the complete DIY home security starter kit — a five-component wireless system that covers the three fundamental layers of home intrusion detection (room motion, door and window entry, and alarm hub), installs in under an hour with no tools, and runs indefinitely on battery power with no monthly subscription fee.

The kit contains everything needed to go from box to protected:

HomeBase 2 — the central hub that connects all sensors, sounds the alarm when triggered, and bridges the system to the internet for app control and alerts. Stores data locally without cloud subscription requirements. Serves as the expansion foundation for additional eufy sensors and cameras.

Keypad — the wall-mounted PIN entry terminal for arming and disarming the system from the home's entry point. Transitions between Home, Away, and Disarmed modes in seconds without opening the app. 6-month battery life.

Motion Sensor — wireless PIR detector covering 100° at 30 feet for full room coverage. Adjustable sensitivity for pet filtering. 2-year battery life.

2× Entry Sensors — door and window contact sensors that alert immediately when a monitored opening is breached while armed. Attach via included adhesive mounts. 2-year battery life each.

No monthly fees is the specification that most differentiates the eufy system from ADT, Ring Alarm, and SimpliSafe. The 5-Piece Kit delivers instant app alerts, remote arm/disarm, and full sensor history at no ongoing cost. An optional 24/7 professional monitoring service is available for an additional fee if response escalation is desired — the core system functions fully without it.

The system links with eufyCam and all eufy Security products — add outdoor cameras, video doorbells, and additional sensors using the same app and HomeBase infrastructure.
