Advantages: Will not damage the overall beauty of the prevention area, simple installation, easy operation, and you will learn it right away. The wireless call intercom system adopts voice digitization technology, communication chip and standard communication software protocol, frequency hopping communication, strong anti-interference ability, harmonious coexistence with hospital equipment, very reliable communication, and basically not involved in oxygen supply system. Each extension is independent. If a certain extension fails, it will not affect the entire system. The system generally uses low-voltage weak current lines, with long standby time and easy replacement and maintenance; the failure rate of each unit of the system is extremely low.

Disadvantages: wireless has distance limitations, too large a building range will limit the use distance; the price will be slightly higher than wired systems.
