Axis C1211-E Network Ceiling Speaker is an all-in-one speaker that makes audio announcements smart and easy. Differing only in size and sound pressure, the speaker system is easy to integrate with video management software (VMS), VoIP telephony, analytics, and more. Like all Axis network audio devices, the new speaker connects to standard networks and uses one network cable for both power and connectivity (Power over Ethernet). Including a preconfigured digital signal processor (DSP), the speaker systems produce clear voice every time and feature a built-in microphone enabling remote health testing and 2-way audio talk-back. Axis C1211-E (small) offers flexible, discrete recessed ceiling installation with embedded audio management software that supports user, content, zone, and scheduling management. While typically used indoors, speakers can also be installed in sheltered areas, such as under the eaves of buildings.
