Network Time Synchronization Solutions: POE vs WiFi Digital Clocks
Power over Ethernet (POE) clocks make for a cost-effective and easy-to-maintain installation. They are energy efficient and draw their power through your internet network. Because of their simple configurations, they have become quite popular for synchronizing time in schools, businesses, and hospitals.
On the other hand, WiFi digital clocks do not require cables for network time synchronization. They can be suitable for facilities that require a few devices over a large area. However, the type of network clock you choose will depend on factors such as accessibility. Here are a few points to help you make the decision.
Availability of Outlets and Connection
Both POE and WiFi clocks can keep accurate time without the need for a master clock for timekeeping. If you have access to a reliable Ethernet connection, it is a more energy-efficient installation than other wired options.
A POE clock is beneficial for buildings where there are few electrical outlets. Because it can draw power from the network cable, you can use it anywhere in the facility, as long as you can get a connection.
If you have problems connecting the device to the Ethernet, WiFi digital clocks may be a better option. With a strong wireless network, you will not require an electrical outlet to make the clock system work.
Some clocks that use WiFi are powered by a battery and do not require an electrical outlet. They can run for more than five years without losing their accuracy in the synchronized clock systems. WiFi clocks can provide a lot of flexibility in buildings where it may be challenging to access Ethernet connections and electrical sockets.
Strength of Network Connections
A WiFi and POE clock should both be easy to configure. Depending on the manufacturer and features, they can even come ready to install. Besides network time synchronization, they also can provide timely weather, alerts, and scheduled information.
One problem with WiFi time devices is that they can be susceptible to electromagnetic interference. Some locations may have electronics that produce strong waves that compromise the way the device works, like in hospitals. Also, the range given by the manufacturer will depend on whether there is a clear line-of-sight. If there are obstructions, the link to the network will be weak and ineffective.
You could opt for a wired POE clock system since they do not have the signal issues that you may encounter with WiFi digital clock. A network with a properly installed infrastructure is seldom prone to electromagnetic interferences. However, some organizations may be better off with a WiFi system because they already have an existing wireless network. Setting up an Ethernet connection can be costly and time-consuming for such situations.
Rely on Time Machines Today
PoE and WiFi wall clocks can both be cost-effective options for synchronizing time throughout your organization. While POE clocks get both power and time updates over a single Ethernet cable, WiFi wall clocks require a separate power source such as a 12V DC power supply. But before you choose any time device, rely on TimeMachines to help you make the right decision.
