This wireless door chime system provides an effective entry alert solution for business, office, and home environments. The set includes one receiver and three sensors, offering coverage for multiple entry points such as doors, gates, or windows. Each sensor transmits a signal up to 500 feet in open areas, ensuring reliable detection even in larger spaces. The receiver features 51 selectable ringtones with adjustable volume levels, allowing users to choose distinct sounds for different sensors or environments.

The unit operates on standard batteries, with low power consumption extending battery life. The construction of both sensor and receiver uses durable ABS plastic, resistant to everyday wear and minor impacts. The sensor’s weather-resistant housing enables outdoor installation on door frames or other exposed surfaces.

The device responds to door opening by triggering the chime instantly, with minimal delay. This real-time alert feature supports child or toddler safety monitoring, as well as security awareness for office or store entries. The system does not require wiring or professional installation; adhesive strips or screws are included for simple mounting.

The adjustable volume—from a soft chime to a loud ring—accommodates different noise levels in busy settings. The 51 built-in melodies cover classic doorbell tones, nature sounds, and electronic alerts, providing variety without complexity. The receiver’s compact design fits on a desk, shelf, or wall, and the LED indicator confirms signal reception.

The product supports multiple receivers added to the same sensor system if expansion is needed, though only one receiver is supplied. The overall performance offers consistent sensitivity and range under typical conditions, with minimal interference from walls or common household appliances. The price point represents a balance between functionality and cost, making it suitable for budget-conscious users seeking dependable entry alerts.
