Axis network speakers connect to your standard network and use one network cable for both power and connectivity (Power over Ethernet). With everything in one solution, installed on one network, there’s no need for additional audio equipment or cabling, and it’s easy to add or remove speakers. This enables more flexible, scalable, and cost-effective solutions. The bottom line? AXIS C1211-E offers a future-proof solution that follows your business needs and gives you the flexibility and possibility needed to quickly respond to future changes.
Smart features at the edge
This all-in-one ceiling speaker is packed with smart features to ensure great performance. With support for I/O, it enables various use cases when integrated with other systems and devices such as PIR sensors, buttons, strobe lights, and more. It features a preconfigured digital signal processor (DSP) to produce clear voice every time. And the built-in microphone supports 2-way audio talk-back enabling conversations with people near the speaker. It also supports speaker-test functionality for remote health testing – so you can rest assured that your system is working. Plus, thanks to external microphone input, you can connect an additional microphone that can be used in situations where the speaker is installed far from the audience.
Another smart feature is the built-in and clearly visible LED which adds visual status information ideal for many different use cases.
In addition, our AXIS Audio Manager Edge application comes built-in to let you efficiently manage and control your audio system. It includes functionalities such as zone management and scheduling of content. And you can prioritize content so that live voice messages always take priority – ensuring that critical information like emergency announcements and paging is always delivered promptly. If you need to coordinate audio across different sites, a standard version of our multisite management software, AXIS Audio Manager Center, is available free of charge.
