Intercom Doorbell with Two-Way Voice Intercom, 1000m Range, Rechargeable, for Home and Office

Simple Setup, No Wiring Needed This intercom doorbell is ready to use straight out of the box with no network or cabling required. The outdoor unit runs on a rechargeable 2000mAh battery, offering up to 8 months of standby time, while the indoor chime operates for about a week on its own charge. A low battery voice prompt and a doorbell indicator light help you keep track of power levels. Clear Two-Way Communication Built-in high-sensitivity microphone and speaker support two-way voice communication, allowing you to speak with visitors clearly. The smart intercom chip provides strong signal penetration, making it suitable for use from the 1st to the 8th floor. Reliable Range for Various Settings In unobstructed environments, the doorbell offers a range of up to 1000 metres. In obstructed conditions, the detection distance is between 20 and 50 metres. This makes it a practical choice for home security, offices, classrooms, hotels, villas, factories, and hospitals.
