NTP, PoE

Power over Ethernet (PoE) / Network Time Protocol (NTP) clocks can connect straight to your local area network (LAN) or through a Master Clock connected to your local area network (LAN). No AC plug is required, so installation is inexpensive and its easy to move clocks around. Power is supplied over 4 pair Unshielded Twisted Pair (UTP) (Cat4 and above) using the IEEE 802.3af Power over Ethernet (PoE) standard. This is a highly accurate system that receives time updates automatically over the network resulting in complete synchronisation throughout the location. Some ranges of these clocks can be configured for both Unicast and Multicast setups. As all NTP clocks use time offsets from Universal Time Coordinates (UTC) the clocks are an ideal base to make a world clock system.
