A Four-Part Guide to Buying a Synchronized Clock System from Pyramid Time Systems – Part 3 of 4

When Power over Ethernet (PoE) Is the Right Fit

In Part 1 of this Sync Guide, we introduced why synchronized clocks matter. Part 2 explained how RF Wireless systems can simplify installs in buildings where wiring can be difficult.

Now in Part 3, we look at another popular option: Power over Ethernet (PoE). This method is ideal for new construction and facilities with modern networks. It delivers both power and time updates through a single Ethernet cable to each clock.

What Is PoE?

PoE stands for Power over Ethernet. It’s a networking technology that sends electricity and data over standard Ethernet cables (the same kind used to plug into computers or printers).

Each clock plugs into a PoE-enabled port on your network. Once connected, the clock receives both time updates and power. This means there are no batteries, extra wiring, or wall outlets needed.

Why PoE Makes Sense

PoE systems are a good choice if your building already has structured data lines in place. You might consider PoE if:

• You have an IT-managed network with Ethernet in key locations
• You want a lower-maintenance system (no battery replacement)
• You’re planning a new building or network upgrade

Industries using PoE clock systems include:

• Schools and Universities
• Government Buildings
• Office Campuses
• Data Centers and Tech Hubs
• Healthcare and Research Facilities

How It Works and Time Sources Options

Pyramid’s PoE synced clocks connect to your network with an Ethernet cable. Each clock is assigned an IP address on your network using DHCP and uses NTP as a time source.

NTP (Network Time Protocol) is the most common time server. Many NTP servers are publicly available and are free to use as a source for accurate time.

Planning with Your Facility Details

Pyramid works with you to determine how many clocks are needed and where you want to place them. Some key considerations include:

• Type of clocks: analog or digital
• Areas that need high visibility, like lobbies or hallways
• Mounting options: wall, ceiling, or dual-sided
• Cabling paths and network switch capacity

PoE clocks are often deployed during network upgrades or construction projects to keep wiring clean and efficient.

Key Benefits of PoE Clock Systems

• Uses existing Ethernet cabling
• One cable for both power and data
• No batteries or external power needed
• Centralized control and easy adjustments
• Multiple Zones
• Infinite amount of clocks on same VLAN

Next Steps

Synchronized clocks using PoE is a great fit for network-ready buildings. But it’s not the only option. In Part 4, we’ll cover Pyramid’s solutions for upgrading or replacing legacy clock systems. These are systems that are using older wired clocks, especially in schools and hospitals that already have infrastructure in place.
