Systems > Power Over Ethernet Clock System
The IP System is offered in both analog and digital clocks. It utilizes the Power over Ethernet infrastructure which provides power and data through the same CAT5 or CAT6 cable. The PoE clocks are typically powered with a PoE (Power over Ethernet) Switch or a PoE Injector. One of the biggest advantages to this system is that no master clock is required since each clock can receive the time data directly from the NTP /SNTP time source. Another terrific feature is that the system allows the user to select up to ten NTP/SNTP servers for redundancy (repetitiveness). Each IP clock can be controlled individually using a built-in web interface, enabling the administrator to easily set may send status alerts by e-mail to the administrator.
