Key Features

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.

System Architecture and Core Modules

An interior receiver (bell) and an outdoor transmitter (button) make up the full system.

1. Outdoor Transmitter
Power Generation Module: Technology selection includes Electromagnetic induction generator (mainstream, mature) or piezoelectric ceramic generator (simpler structure, lesser power output).
Mechanism: Pressing the button drives a magnet through a coil or compresses piezoelectric material, resulting in immediate AC current.
Signal Processing and Transmission Module: Equipped with a low-power microcontroller (Main Control MCU) activated when enough kinetic energy is present.
Mechanical and Structural Module: Engineered button tactile design that balances actuation force, travel distance, and power generation efficiency while delivering adequate tactile feedback.
Housing & Protection: High protection rating (IP65+), rainproof, dustproof, and temperature-resistant.
Mounting Options: Supports 3M sticky pads, screw mounting, and other fast techniques.
2. Indoor Receiver
Plug-in Power Module: Connects directly via standard plug (USB/power adapter).
Wireless Receiver Module: Fully compatible with the outdoor transmitter wireless protocol.
Alert and Interaction Module: Features polyphonic ringtone support via a built-in high-quality speaker and multi-level volume adjustment.
Controls & Indicators: Physical buttons include volume control, ringtone selection, and a pairing button. Indicator lights show power, pairing status, and operating conditions.
Primary Use Cases:
  • 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.

Frequently Asked Questions
How does the transmitter work without a battery?

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.

What is the actual wireless operational range?

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.

Can the transmitter withstand outdoor weather conditions?

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.

How is the doorbell installed on different surfaces?

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.

Can I adjust the chime sound and volume?

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.

Which plug options are available for the indoor receiver?

The indoor receiver supports standard AC 100-230V working voltage and is available in EU, UK, and US plug specifications to accommodate international standards.
