NTP clocks connect to your existing network to pull time from an Internet time server. It’s one of the fastest and most cost-effective ways to get synchronized time! Quality construction and precision engineering means that maintenance staff won’t have to spend time fixing clocks.

NTP master clock is a NTP PoE clock with a built-in radio module and a GPS antenna. It synchronizes with a NTP server, other slave clocks can synchronize with it.

The NTP (Network Time Protocol) time server is based on signals from global positioning satellites (GPS and BDS) as the reference source. The time reference in the GPS/BDS satellite signal is synchronized with Coordinated Universal Time (UTC), and the long-term frequency stability reaches the level of 10-13 of cesium atomic clocks, equivalent to slowing down by only one second every 300,000 years.

IP network clocks are connected to your exsisting network. They can synchronize with public internet NTP server or private NTP server. They can work anywhere where there is network and they are much accurate and reliable. IP network clocks are widely used in schools, hospitals, offices, home, power plants, train stations, airports...

Wi-Fi Network Clocks
Easy set up. Zero maintenance. Accurate time.

Powered by network.

Time is real!

Power over Ethernet (PoE) clocks are a durable and precise technology that delivers accurate time anywhere. PoE clocks draw both power and time updates from your organization’s Ethernet connection and eliminate the need for AC receptacles and the use of batteries. Our beautiful analog PoE clocks give you accurate time and peace of mind.

How PoE Clocks Work

Digital PoE clocks draw both power and time updates from your organization’s Ethernet connection. PoE clocks are energy-efficient and eliminate the need for AC receptacles and the use of batteries. You’ll love the hassle-free installation and maintenance of these synchronized clocks!
