What is the Distinction Between a Wi-fi and Wired Clock System?

Years in the past, wired clock methods had been the usual, dependable methodology to maintain synchronized time in colleges and companies. Right now, these clocks are nonetheless manufactured, however there are additionally wi-fi choices, which make the most of extra fashionable expertise to rework timekeeping.

So, which resolution is finest in your faculty or amenities?


Similarities Between Wired and Wi-fi Programs

Each wired and wi-fi methods use a grasp clock (also called a system controller) to remain up to date on the proper time and preserve synchronization among the many clocks within the system. Likewise, the controllers in each sort of methods routinely replace for Daylight Saving Time modifications, are simply programmed by way of an internet interface, can schedule varied methods to change ON/OFF routinely, and may management 12- or 24-hour codecs for digital clocks. 

Past these primary similarities, nevertheless, wired and wi-fi methods are very totally different.

Wired Clock System

A wired timekeeping system has a grasp clock that’s bodily wired to every clock in a constructing and, utilizing an Ethernet connection to a time server, controls the displayed time to take care of synchronization. In most wired methods, the grasp clock makes use of a twin correction scheme. The correction protocols usually differ between fashions and producers, however sometimes synchronizes the minute and second fingers each hour, together with a 12-hour correction to maintain the hour hand synchronized. This ensures that the clocks will routinely right after most extended energy outages, whereas nonetheless protecting the synchronization correction largely unnoticeable.


Colleges historically used wired clock methods for 2 primary causes: rock stable reliability and the flexibility to synchronize faculty bells to the remainder of the system. The wired synchronized system ensured that clocks would all learn the identical time and bells would ring on the identical time day by day, it doesn’t matter what classroom you had been in, and that college students would arrive to class on time — one thing academics might solely dream of earlier than putting in a synchronized system. 

The AllSync Plus® system from American Time, like all wired methods, has fewer transferring components and makes use of a bodily hard-wired connection between the grasp clock and system clocks, which makes them extra dependable and simpler to take care of. AllSync Plus clocks provide a number of advantages together with:

  • Trouble-Free Accuracy — Correct to ± 1 second to the grasp clock. 
  • Distant Entry — Remotely handle all of your gear from the comfort of any system with an web connection and net browser.
  • Power Saving — Makes use of as much as 80% much less power than common mechanical clocks.
  • Plug and Play — Simple to put in clocks as a result of AllSync Plus clocks are shipped with our polarized, color-coded Molex® plug. 
  • Backup Plan — An inside capacitor retains all clocks working for as much as quarter-hour with out batteries within the occasion of an influence outage.

Wi-fi Clock System

Wi-fi clock methods harness the facility of radio alerts to offer the identical performance of a wired system with out the bodily infrastructure necessities. As an alternative of working wires between the grasp clock and each system clocks, the grasp clock transmits a correction sign to the clocks to take care of wi-fi synchronization, making it a really perfect resolution for buildings with out present wiring for synchronized clocks or for increasing an present wired system without having to put in further wiring.

These methods provide the identical excellent accuracy as wired methods, and may also synchronize faculty bells and different gear, due to the facility of wi-fi relays.


Superior wi-fi clock methods like our SiteSync IQ® can seamlessly combine with present wired methods or perform independently to create a totally new wi-fi system. Just like the wired AllSync system, the SiteSync IQ system may be remotely managed. The SiteSync IQ system is flexible, with many advantages:

  • Better of Each Worlds — A hybrid resolution can create a clock system that runs your present wired clocks and wi-fi clocks. This helps you add wi-fi clocks when and the place you select to primarily based in your finances. 
  • The Sky is the Restrict —A limiteless variety of clocks can use the time synchronization sign. Protection is accomplished utilizing a single transmitter with a alternative of 5 watt to 30 watt system controllers.
  • Batteries with a Lengthy Life — American Time clocks with Battery Booster Packs last as long as 5 years, that means battery clocks may be put in in any location and supply years of maintenance-free service.
  • Plug It In — Electrical is an choice too, with solely the facility supply requiring a wire. 

These are just some of the options out there for every clock system choice. To get solutions particular to your constructing’s wants, contact American Time for a free session. A clock adviser will assess your present timekeeping system and aid you decide one of the best resolution in your present and future wants.
