BRG DuraTime Wi-Fi Synchronized Clocks — Sync to the Network You Already Have
By BRG Precision Products | July 31, 2026 | Synchronized Clocks • Wi-Fi
Your facility already has Wi-Fi. It reaches your employees, your students, your patients, and your work areas. So why run new wires or purchase a separate master clock system just to synchronize your clocks? BRG’s DuraTime Wi-Fi Synchronized Clock System leverages the Wi-Fi infrastructure you already have to keep every clock perfectly in sync — automatically, reliably, and with minimal setup.
DuraTime Wi-Fi clocks connect to your 2.4 GHz Wi-Fi network and pull time from any NTP server — your internal server, a BRG NTP100B GPS Time Server, or any public internet time source. No master clock hardware to purchase, no sync wires to run, no complex IT configuration required. Every clock automatically adjusts for Daylight Saving Time and displays in 12 or 24 hour format.
Key Features
No Master Clock Required
DuraTime Wi-Fi clocks sync directly to any SNTP/NTP server on your network. No expensive master clock hardware is needed — just an NTP source and your existing Wi-Fi network.
User-Changeable 7-Color LEDs
Every DuraTime Wi-Fi LED digital clock includes user-changeable multi-color LEDs. Change any clock to Red, Blue, Green, Yellow, Magenta, Cyan, or White at any time. 3X more LEDs than competing products for brighter, more legible digits.
Password-Protected Web Interface
Each clock has a built-in web configuration page accessible from any browser on your network. Configure the NTP server, time zone, DST rules, and display format without discovery software or IT involvement. Every analog and LCD DuraTime Wi-Fi clock also includes a small OLED display on the back showing the current time and network connection status.
802.11 b/g/n/e/i • WPA/WPA2 PSK • DHCP
BRG’s proprietary communications technology uses very low bandwidth, allowing thousands of clocks on the same network. AES 128-bit hardware encryption, Wi-Fi Direct (P2P) support, and automatic IP addressing via DHCP are all standard.
Battery-Powered Analog Models Available
DuraTime Wi-Fi analog clocks are available that run up to 15 years between battery changes, thanks to BRG’s proprietary battery-saving technology. No AC power wiring required for these models whatsoever — just Wi-Fi coverage.

Frequently Asked Questions
Q: Do DuraTime Wi-Fi clocks require a dedicated master clock?
No. They sync directly to any NTP server on your network. Pairing with a BRG NTP100B GPS Time Server provides GPS-disciplined accuracy, but any NTP source — including public internet time servers — will work.
Q: How many clocks can run on one Wi-Fi network?
As many as your network can support based on available IP addresses. BRG’s proprietary low-bandwidth communications technology allows thousands of clocks to operate on the same network without impacting performance.
Q: Are DuraTime Wi-Fi clocks available on GSA contract?
Yes. Multiple DuraTime Wi-Fi models are available through GSA Multiple Award Schedule contract # 47QSMS26D002K, SIN 339950. BRG sells exclusively direct — no authorized third-party resellers.
