HENDUN Motion Sensor Door Bell Chime for Business — Wireless Receiver, 36 Ringtones, 918ft Range

Overview

HENDUN Motion Sensor Door Bell Chime is a versatile, wire-free alert system designed for busy storefronts, small businesses, offices, and homes. The detector can be placed at entry points or in corridors where movement is expected, while the compact receiver sits inside the space you want to monitor. When motion is detected, the receiver emits a signal, delivering an audible cue, a simple reminder, or a moment of reassurance.

Setup is fast and clean thanks to its wire-free design and dual-power options: batteries or USB power. The doorbell-style receiver supports 36 ringtones, giving you a broad spectrum from melodic tones to straightforward buzzers, plus 5 welcome ringtones tailored for retail environments. The system is optimized for indoor use or sheltered spots outdoors, and it is designed to cover large spaces with a transmission range up to 918 feet between units and a detection reach of about 13–26 feet for the sensor.

Why it stands out

Beyond simple motion notification, this device acts as a flexible alert companion for people managing entrances, safety in elder care, or inventory awareness. The combination of wide range, audible options, and easy placement means you can tailor sounds and coverage to your layout and traffic flow.
