Daisy chaining connects multiple devices in series over a single cable run, mirroring the simplicity of a floral garland. Originally used in electrical circuits, it’s now pivotal in PoE networking—delivering data and power through one Ethernet cable. While reducing clutter and enabling modular expansion, daisy chains introduce single points of failure and power-budget limits. The Nearity A21S leverages PoE daisy chaining (up to 8 units) and advanced AI 2.0 noise, echo, and reverberation cancellation to deliver seamless 360° voice capture in conference rooms. Certified for Zoom, Teams, and Meet, it offers plug-and-play compatibility across major platforms and operating systems, making it an ideal solution for scalable, high-quality audio installations.
Have you ever been in a conference room and struggled to hear someone across the table? Or found yourself wrestling with a tangle of cables just to get multiple devices talking to each other? If so, you’re not alone. I’ve been there too—wondering how to link my speakerphones, cameras, and monitors without tripping over cords or losing audio quality. In this post, I’ll walk you through everything you need to know about the daisy chain concept—from its roots in electric wiring to its modern role in POE networking—so you can transform your meeting spaces, small or large, into audio/video powerhouses with the Nearity A21S solution. Let’s dive in!
What is Daisy Chain?
When I first heard the term daisy chain, I pictured a floral garland—one daisy after another, each connected by stems. This is also the origin of this term. Technically, that’s not far off. In networking and electronics, a daisy chain refers to a wiring scheme in which multiple devices are wired together in sequence or in a ring,similar to a garland of daisy flowers.
Why "daisy chain" matters
- Simplicity: You only need one cable run between devices, reducing clutter.
- Modularity: Add or remove devices without rewiring the entire network.
- Scalability: Chain as many units as the protocol or power budget allows.
But like a real flower chain, the strength of the whole line depends on each link—weak stems mean a drooping garland. Likewise, signal integrity and power delivery must be managed carefully in electronic daisy chains.

Daisy Chain Explained: From Electric Wiring to PoE Networking
From light switches to speakerphones
In the world of electrical installations, daisy chain electric wiring is a classic technique. Imagine wiring multiple light fixtures on a single circuit: you start at the power source, connect the first fixture, then run a cable to the next, and so on. This circuit daisy wiring approach saves cable and installation time. However, if one fixture or cable fails, any downstream device loses power — a classic single point of failure.
Enter PoE: Power Over Ethernet
Fast-forward to modern conferencing and surveillance: PoE delivers both data and power over a single Ethernet cable, which becomes a game-changer for conference room connection.
How daisy chaining works in PoE networks
- Midspan Injector or Switch A PoE switch or injector provides power at the network’s origin.
- Primary Device The first device (e.g., a speakerphone) draws power/data and passes spare pairs downstream.
- Secondary Device(s) Subsequent devices tap into the same cable pairs for power and data—up to the maximum power budget.
By leveraging PoE daisy chains, you eliminate separate power cables, simplify deployment, and keep your ceiling or wall installed clean. Just be mindful of the power budget: each device consumes watts, and the PoE switch must supply enough for all chained units.
The Advantages and Disadvantages of Daisy Chain in Conference Meetings
Every technology has trade-offs. Here’s my take on linking devices in a daisy chain.
Advantages
- Reduced Cabling Complexity One cable serves multiple devices—goodbye, spaghetti junction!
- Modular Expansion Need to add a mic or camera? Plug it into the end of the chain.
- Cost-Effective Fewer cables and ports mean lower infrastructure costs.
- Simplified Maintenance Isolate issues by unplugging one segment without disturbing the whole system.
Disadvantages
- Single Point of Failure If one link breaks, all downstream devices lose signal or power.
- Signal Degradation Long chains can introduce latency or reduced data throughput.
- Power Limitations PoE budgets cap the number of devices you can chain.
- Troubleshooting Complexity Identifying a faulty cable or device in a long chain can be tedious.
Ultimately, daisy chaining shines when you need moderate scalability with minimal clutter. For ultra-reliable or mission-critical setups, consider a star topology with a central hub.
