The system's shell is made of aluminum alloy, with a 5W high-quality speaker and a split-style microphone design that ensures clear and bright sound. The independent internal and external mute switches are designed for silent control as required. Special 4-core high-strength aluminum foil shielded cables are used for strong anti-interference capabilities, ensuring clear and natural sound. The bidirectional voice intercom communication technology can automatically identify voice signals during the call process without any operation. It is suitable for banks, securities companies, hospitals, and stations where anti-theft glass is installed.
