[Long-Range Communication]: Our wireless two-way intercom system is designed for long-range communication, with a tested range of up to 300 meters. It can penetrate walls and floors, enabling clear communication from the 1st to the 8th floor. This makes it suitable for elderly care, home, or office communication. [Slim and Sleek Design]: With a thickness of only 18mm, our intercom system is slimmer than many similar products on the market, which are typically over 22mm thick. The slim profile, combined with a high-gloss UV-treated finish and a plastic + silicone button structure, provides a comfortable and premium tactile experience. [Intelligent and User-Friendly]: The intercom system features user-friendly functions such as talk light and battery level indicators for easy monitoring. It includes a charging dock for convenient smart charging, ensuring the device remains powered and ready for use. [High-Capacity Battery]: Equipped with a 1800mAh polymer lithium battery, the intercom system lasts approximately one week under normal usage (5 calls per day, 1 minute per call). It offers a standby time of 3–5 days, making it a reliable communication solution for home or office environments. [Versatile and Adjustable]: The system supports two frequency options (462MHz and 434MHz) to help reduce signal interference. It offers 38 ringtone choices and 3 adjustable volume levels for both ringtones and call o. Please note that the two units are designed to work together as a pair and cannot operate independently.
