Dual Reminder and Power Supply: This bed alarm system for the elderly features both LED lights and audible alerts to ensure prompt attention. It can be powered by either alkaline batteries or a Micro-USB, providing flexibility and reliability in power sources for continuous operation. Effectively Monitor Elderly Individuals' Movements: Strategically place the wireless motion sensors under the bed or at doorways to detect movement. The system triggers an alarm when an elderly person attempts to leave the bed or room, enhancing safety and providing caregivers with peace of mind. Extended Wireless Range: Enjoy the freedom to move the receiver within a range of over 500 feet (150m+) without losing signal. This feature allows caregivers to perform their daily tasks anywhere in the home or yard without losing connection to the monitored individual. Ready to Use: The sensor and receiver are pre-paired for immediate use. Simply power on the system, and it performs a self-test by flashing the indicator light 5 times and becomes operational in just 20 seconds, ensuring no time is wasted during setup. Customizable Alerts: Tailor the alert settings to meet specific needs with 17 different ringtones and volume adjustments from 0dB to 110dB. The vibration mode offers a discreet alerting option that minimizes disturbances to others while still notifying the caregiver.
