1. Ultimate Convenience: Achieves "one-time installation, permanent use" (during its physical lifespan) by completely removing the inconvenience of battery change.
2. Eco-Friendly & Energy-Efficient: Using no batteries lowers carbon emissions and eliminates heavy metal pollution.
3. Installation Freedom: The outdoor unit can be mounted anyplace (metal doors, glass, stone) without the need for wiring. The indoor unit is movable.
4. Stable & Dependable: Unaffected by battery deterioration, successfully avoiding unexpected low-power operational failures.
An interior receiver (bell) and an outdoor transmitter (button) make up the full system.
- Residential users (single-family homes, apartments, and renovated older communities).
- Bed and breakfasts, modest studios, and retail stores.
- Individuals seeking highly reliable, eco-friendly technological solutions.
- Households with elderly or youngsters who may forget battery replacements.
The transmitter utilizes micro-energy harvesting technology (electromagnetic induction or piezoelectric ceramic). Pressing the push button generates instantaneous kinetic energy, converting it into electrical power to send the 433MHz wireless signal to the receiver.
The device features an operating transmission range of up to 150 meters in an open, obstacle-free environment. In typical indoor residential applications with walls and partitions, effective transmission distance reliably covers standard household layouts.
Yes, the outdoor transmitter is enclosed in an IP65+ rated housing that is waterproof, dustproof, and engineered to endure operating temperatures between -10°C and +45°C.
The outdoor unit requires no electrical wiring and can be easily installed on smooth surfaces such as glass, metal doors, wood, or brick walls using the provided high-strength 3M adhesive tape or mounting screws.
Yes, the indoor plug-in receiver features built-in volume control buttons allowing you to choose multiple volume levels (>50dB/1m+) along with selectable polyphonic melodies to match your preference.
The indoor receiver supports standard AC 100-230V working voltage and is available in EU, UK, and US plug specifications to accommodate international standards.
