NineLeaf Wireless Motion Sensor Door Chime — 5PK, 48 Ringtones, 5 Volume Levels (97dB), 433MHz, 1300ft Range, 4 Modes — Home/Office/Hotel

Compact, easy-to-set-up motion chime system ideal for homes, offices, hotels and outbuildings. The receiver plugs into a standard outlet for instant operation, while the detector mounts with screws or double-sided tape. Its rotatable base lets you aim the unit precisely — 360 degrees horizontally and 180 degrees vertically — for the best coverage. Four operating modes (Welcome, Doorbell, Alarm, Nightlight) let you tailor alerts to different situations. The motion detector senses activity at gates, porches, driveways, walkways, pools, sheds and more, and immediately notifies the receiver when motion is detected. Pick from 48 built-in ringtones and five volume settings, with a maximum output of 97dB so you won’t miss an alert. A silent flashing mode is available for visual alerts, and the soft night light offers seven brightness levels to suit different needs. Using 433MHz wireless technology, the set provides a dependable signal with a control range up to 1300ft, including through-wall operation. The DIY pairing function supports connecting one doorbell receiver to up to 32 wireless buttons for flexible coverage. Energy-efficient design: receiver standby power consumption is 100mW (about 0.8 kWh per year). The detection transmitter accepts battery power or USB power (dual power supply). Note: the detector is not waterproof.
