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.
