Learn all about them here.
Large facilities, such as schools, manufacturing facilities, hospitals and corporations, generally have three options when it comes to timekeeping: serial, wireless and Power over Ethernet (PoE) clocks. This is because of the time synchronization these clock systems provide. Keeping everyone on the same time in your organization is vital. Below is a description of each type of clock system with information on how you can learn more.
1. Serial Clocks
Serial clock systems have been around for many years. These clocks require a 110V outlet and a serial plug for power. Another power option is an extra pair of wires for 24V DC power in case of a power outage. The wiring these clocks require make serial clock systems an expensive solution, compared to Power over Ethernet clocks.

2. Wireless Clocks
Wireless clocks are essentially the second generation of clock systems. These clocks receive time from a transmitter that must be located in the building. The transmitter sends a low wattage signal with the time to each clock. Analog clocks require little power and can be operated by batteries. Digital clocks require more power and use AC outlets. Typically less expensive than serial clocks, digital wireless clocks require expensive AC outlets to be installed and analog wireless clocks need battery replacements.

3. Power over Ethernet Clocks
Power over Ethernet (PoE) is an exciting and relatively new technology that simplifies implementation and maintenance of a clock system. There is no need for AC outlets, battery replacements, daylight saving time adjustments or additional software. A network administrator can easily control one or hundreds of clocks from any PC on the network with a simple Telnet session. The option of centralized UPS backup allows PoE devices to continue running even in the event of a power failure. Inova OnTime® PoE clocks come in digital and analog formats.
