You get consistent performance without the hassle of frequent battery replacements. Extended Signal Range With a stable power supply from the adapter, this doorbell can transmit its signal over longer distances, reaching up to 300 meters. This makes it ideal for larger properties or for locations where batterybased doorbells might struggle due to weak signals. Whether you live in a multistory house, have a detached garage, or work in a spacious office, this doorbell delivers reliable coverage. 36 Selectable Ringtones and Adjustable Volume Featuring 36 different ringtone options, you can choose the chime that suits your preference and home environment. The adjustable volume settings allow you to set the sound level to match your needs, from a soft tone for quiet areas to a louder alert for busy or noisy spaces. Visual Flash Notification In addition to sound alerts, the doorbell features a blue flashing light that activates when the button is pressed. The button itself briefly illuminates upon pressing, providing immediate feedback to the visitor. The flashing light is particularly useful for individuals with reduced hearing or in situations where you prefer a silent visual signal.
