Digital School Broadcast System and School Bell with Bluetooth

A digital 2-way audio broadcast system is a communication network that allows for both one-way broadcasting and two-way, interactive communication. Unlike a traditional public address (PA) system that only allows for one-way announcements, a two-way system enables the person making the announcement to receive a response from a specific location, or for that location to initiate a call to the central unit. This is often used in schools, hospitals, factories, and other large facilities to enhance safety, management, and efficiency.
