The CallToU Wireless Motion Sensor Alarm system comprises one sensor and one receiver, designed to provide reliable motion detection for indoor spaces. Its construction utilizes durable ABS plastic housing, ensuring resistance to everyday wear while maintaining a lightweight profile for easy placement. The sensor employs passive infrared technology to detect movement within a designated area, with an operating range of up to 500 feet in open conditions, allowing coverage across multiple rooms or a single large space. The receiver features five adjustable volume levels, from a soft chime to a louder alert, accommodating various hearing sensitivities and ambient noise levels. This product is particularly suited for monitoring elderly individuals with dementia, serving as a bed alarm or door chime to alert caregivers of movement. The system operates on standard batteries, with low power consumption contributing to extended battery life and consistent performance. The alarm tone is clear and distinct, minimizing confusion while ensuring it captures attention without being excessively jarring. The receiver includes a compact display that indicates the signal strength and activation status, enhancing usability.

The hardware is well-assembled with secure fittings and responsive buttons, reflecting attention to practical engineering. The straightforward pairing process between sensor and receiver eliminates complicated setup requirements, making it accessible for users with limited technical experience. The motion sensor has a detection angle of approximately 120 degrees, covering a broad field while avoiding blind spots typical of narrower sensors. The outdoor-rated receiver can be placed on a tabletop or mounted on a wall using included brackets, offering flexibility in installation. The entire kit is priced very affordably, presenting a cost-effective solution for home safety applications without compromising on essential functionality. Its performance is consistent across typical indoor environments, with minimal false triggers when positioned away from heat sources or drafts. The system is not intended for outdoor use, but its indoor reliability makes it a practical choice for caregivers and families seeking an extra layer of monitoring.
