NineLeaf Motion Sensor Door Chime 3PK — Wireless Door Motion Sensor, 48 Ringtones, 5 Volume Levels (up to 97dB), 1300ft Range, Easy Install — Home/Office/Hotel

Overview: This NineLeaf wireless motion-sensing chime kit delivers instant alerts for entrances and outdoor zones. The receiver is plug-and-play—just insert it into an outlet—and the motion detector mounts easily with screws or double-sided tape. It includes a rotatable mounting base that adjusts 360 degrees horizontally and 180 degrees vertically so you can aim the sensor precisely. Sensing Modes & Coverage: The unit supports four operating modes: Welcome, Doorbell, Alarm, and Nightlight. Use it to monitor driveways, front porches, gates, homes, sheds, offices, walkways, pools, and similar areas; when movement is detected the transmitter immediately notifies the receiver. Sounds & Light: Pick from 48 built-in ringtones and set one of five volume levels, with a top volume of 97dB to ensure you don’t miss alerts. A silent flashing mode provides a visual alert option for hearing-impaired users or quiet environments. The nightlight feature offers seven brightness levels for soft illumination. Wireless Performance & Pairing: Operating on 433MHz wireless technology, the system provides a reliable, interference-free connection with an obstacle-free control range of up to 1300 ft. The DIY pairing capability lets a single doorbell receiver be linked to as many as 32 wireless buttons for flexible coverage. Power & Efficiency: The receiver’s standby power consumption is 100mW (about 0.8 kWh per year) for energy-efficient operation. The detection transmitter supports dual power options: battery and USB. Note: the detector is not waterproof.
