Wireless Battery-Free Smart Doorbell with 120m Range and Kinetic Energy Button, IP44

A Doorbell That Needs Neither Cable Nor Battery

This smart doorbell runs purely on kinetic energy, so there is no cable, no battery, and no risk of a missed visitor from a dead power source.

• Kinetic energy instead of a battery: Every button press generates the power it needs, so there is no battery to replace and no interruption in service for years.
• 120 m radio range: Roughly three times the range of many standard wireless doorbells, so a visitor can be heard whether in the garden, office, or basement.
• 50+ melodies with 100 dB and LED display: Louder signals than a typical doorbell set are combined with a visual display, useful in noisy conditions or for limited hearing.
• IP44 rated for -10°C to 60°C: Weatherproof through all seasons, with rain, frost, or summer heat not affecting function or casing.
