Power over Ethernet (PoE) speakers are innovative audio devices that transmit both power and data through a single Ethernet cable. This technology streamlines installations and reduces the need for additional power sources. The main functions of PoE speakers include delivering high-quality audio for announcements, background music, and emergency notifications. Technological features include built-in amplifiers, noise cancellation capabilities, and compatibility with various network protocols. PoE speakers are ideal for use in a wide range of applications, from educational institutions and retail environments to office buildings and industrial facilities. Their versatility and ease of integration make them a popular choice for enhancing audio communication in diverse settings.
