BRG PoE Clocks — Power-over-Ethernet Synchronized Clocks, One Cable for Power and Time
By BRG Precision Products | August 14, 2026 | Synchronized Clocks • PoE
Installing a synchronized clock traditionally meant running two separate cables to each location — one for power and one for the sync signal. BRG’s PoE (Power-over-Ethernet) Synchronized Clocks eliminate both with a single standard Ethernet cable that carries both power and synchronized time to every clock. If your facility already has Ethernet network drops near each clock location, PoE clock installation is essentially plug-and-play.
BRG PoE clocks conform to the IEEE 802.3af/AT standard, meaning they work with any standard PoE switch, PoE midspan injector, or PoE-capable network equipment. No additional wiring contractors, no electrical outlets to add, no power supplies to mount — just one CAT5 or higher Ethernet cable to each clock location.
How BRG PoE Clocks Work
Each BRG PoE clock connects to your Ethernet network and receives an IP address automatically via DHCP. Time synchronization comes from any SNTP server on your network — your internal NTP server, the BRG NTP100B GPS Time Server, or any public internet time server. The clock synchronizes automatically and adjusts for Daylight Saving Time based on configured time zone rules. All setup is handled through a standard web browser: open the clock’s IP address in any browser on your network and configure the NTP server, time zone, DST rules, and display format. No proprietary software required.
Key Features
Single-Cable Installation
One standard CAT5 or higher Ethernet patch cable from your PoE switch or midspan injector to each clock. No electrical outlet, no separate power supply, no conduit run needed. Fastest installation path of any synchronized clock system for facilities with existing Ethernet infrastructure.
User-Changeable 7-Color LEDs
Every BRG PoE LED digital clock includes user-changeable multi-color LEDs. Choose from Red, Blue, Green, Yellow, Magenta, Cyan, or White at any time. 3X more LEDs than competing products for brighter, more legible displays. Aluminum frame options are available on 4″ models.
No Master Clock Required
PoE clocks synchronize directly to any SNTP server on your network. No dedicated master clock hardware is needed. For GPS-disciplined accuracy, BRG’s NTP100B GPS Time Server integrates seamlessly with PoE clocks.
Factory Pre-Configuration Available
BRG can pre-configure the clock’s time zone and display rules at the factory, so each clock is ready to display correct time the moment it is connected to your network.
PoE Power Injectors Available
If your existing switches don’t support PoE, BRG offers midspan power injectors — 31W (PoEI) and 60W (PoEIBT) — that add PoE power to any standard Ethernet port without replacing your switch. The PE680 8″ clock requires a 60W source; all other models are powered by standard 15.4W 802.3af.

Frequently Asked Questions
Q: Do I need a PoE switch to use BRG PoE clocks?
You need either a PoE-capable Ethernet switch or a midspan PoE power injector. BRG offers 31W (PoEI) and 60W (PoEIBT) midspan injectors that add PoE power to any standard Ethernet port without replacing your switch. Most PE models require only standard 802.3af (15.4W); the PE680 requires 60W.
Q: How do I configure the time zone and NTP server?
Open a web browser on any computer on the same network, enter the clock’s IP address (assigned automatically via DHCP), and access the built-in web configuration page. All settings — NTP server, time zone, DST rules, and display format — are configurable through the browser. No proprietary software required. BRG can also pre-configure the clock at the factory.
Q: Are BRG PoE clocks available on GSA contract?
Yes. Multiple BRG PoE clock models are available through GSA Multiple Award Schedule contract # 47QSMS26D002K, SIN 339950. BRG sells exclusively direct — no authorized third-party resellers.
