1 wireless voice intercom, smart doorbell for indoor/outdoor use, access system with a range of 200 m, residential use

This BellSilver wireless voice intercom consists of a self-contained outdoor unit (powered by 4 AAA 1.5V batteries, not included) and an indoor unit that operates via USB cable. Designed for everyday residential use, it combines technical reliability with easy installation: no electrical wiring or construction work is required. The battery lasts up to 6 months in standby mode, and an LED indicator displays the charge level. The wireless range—up to 200 meters in open space—is based on a stable frequency (467.6375 MHz), minimizing interference in densely populated areas. The ABS outdoor unit is resistant to varying weather conditions (-20°C to 55°C), while the indoor unit features a touch-sensitive answer button and an adjustable speaker for comfortable listening. Compatible with multiple indoor receivers, this system is suitable for single-family homes, apartment buildings, or small commercial premises.
