Our doorbell transmitter uses the principle of converting kinetic energy into electrical energy, making it energy-saving and environmentally friendly. This allows us to enjoy a green and environmentally friendly life brought by technology. Our doorbell set comes pre-paired with the transmitter button and receiver at the factory, so you can use it immediately. Thank you! 2. High Performance: This waterproof mini doorbell button is made of high-quality ABS material, IP68 dustproof and waterproof, and can operate in a temperature range of -15°C to +60°C, resisting various weather conditions. It is suitable for outdoor use even in rainy weather. 3. High Quality: Our doorbell transmitter has undergone professional testing. The transmitter's lifespan can reach 500,000 presses, far exceeding the industry average. 4. Remote Control Range: Approximately 150 meters (open space). Indoor unobstructed distance is 30-50 meters (this data represents the experimental unobstructed test distance in an open space. The actual distance is affected by the operating environment. The more obstacles, the shorter the distance). 5.
