[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, allowing for 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 design, combined with a high-gloss UV-treated surface and a plastic + silicone button structure, provides a comfortable tactile experience. [Intelligent and User-Friendly]: The intercom system features user-friendly functions, including a talk light and battery level indicator for easy monitoring. It includes a charging dock for convenient smart charging, helping ensure the device remains powered and ready for use. [High-Capacity Battery]: Powered by a 1800mAh polymer lithium battery, the intercom system can last approximately one week under normal use (5 calls per day). 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 interference. It offers 38 ringtone choices and 3 adjustable volume levels for both ringtones and call audio. Please note that the two units must be used together as a pair and cannot function independently.
