Rechargeable shop doorbell with infrared motion detector and various melodies

This indoor motion detector not only offers motion detection but also various practical functions: it uses red, blue, and green indicator lights to help you distinguish between different entrances, while providing effective alarms when motion is detected for enhanced security.

【Adjustable Ringtones and Volume】The receiver, designed like a doorbell, offers 36 built-in ringtones to meet your personalized needs. The volume is adjustable from 113 to 25 decibels across four levels: high, medium, and low. The nightlight/colored light mode is quiet and offers four adjustable brightness levels, ideal for the hearing impaired or homes with young children. This mode also offers four colors to choose from.

【Extended Sensitivity and Wireless Range】This motion detector can detect movement over a wide area. The infrared sensor has a range of approximately 4 to 8 meters, allowing you to continuously monitor your surroundings and ensure your safety.

【Numerous Applications】Motion detectors are essential for home security systems. They detect movement in surrounding areas (front doors, patios, gates, hallways, apartments, offices, hotels, shops, and other indoor spaces) and send an alarm to a connected receiver. They provide enhanced security for your home and family.

【Easy Installation and Use】The device is powered by a USB port or batteries (the infrared sensor requires three AAA batteries and the receiver three AA batteries; batteries not included). Both the infrared sensor and the receiver come with a mounting bracket. The infrared sensor rotates 360° horizontally and 180° vertically for easy installation and positioning.
