[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 finish and a plastic + silicone button structure, offers a superior tactile experience. [Intelligent and User-Friendly]: Our intercom system features user-friendly functions including a talk light and battery level indicator for easy monitoring. It comes with a charging dock for convenient smart charging, ensuring the device remains powered and ready for use. [High-Capacity Battery]: Powered by a 1800mAh polymer lithium battery, our intercom system lasts approximately one week under normal use (5 calls per day, each call). It offers a standby time of 3–5 days, making it a reliable communication tool for home or office environments. [Versatile and Adjustable]: The intercom system supports two frequency options (462MHz and 434MHz) to help avoid interference. It includes 38 ringtone choices and 3 adjustable volume levels for both ringtones and call volume. Please note that the two devices must be used together and cannot function independently.
