Q:  Does the PoE digital clock require an NTP server to function?

A: Yes. To ensure high precision and a uniform time source across your facility, the clock synchronizes with either a private or public NTP/SNTP server. This ensures all network-connected devices remain perfectly synchronized within milliseconds, making it ideal for schools, hospitals, and corporate offices.

Q:  How is the network clock powered? (PoE vs. DC)

A: Our clocks are primarily powered through Power over Ethernet (PoE - IEEE 802.3af standard), which allows both data and power to be delivered via a single RJ45 cable. For environments without PoE infrastructure, a 12V DC power input is also available as an optional backup or primary power source.

Q: What time and data formats can the clock display?

A: The standard display shows Hours, Minutes, and Seconds in high-visibility LED digits. The system is fully flexible, supporting both 12-hour (AM/PM) and 24-hour (military time) formats. Additionally, it features automatic Daylight Saving Time (DST) adjustments, eliminating the need for manual seasonal updates.

Q: What are the network configuration options (IP & Redundancy)?

A: The clock is designed for seamless IT integration, supporting both DHCP for automatic setup and Static IP for dedicated network management. For enhanced reliability, you can configure up to five (5) SNTP server addresses, providing multi-level redundancy to ensure the clock remains accurate even if a primary server fails.

Q: Can this clock display temperature or trigger alarms?

A: Yes, we offer modular hardware upgrades to meet specific project needs. Optional features include:

Environmental Monitoring: Real-time temperature and humidity sensors.

Scheduled Alerting: Integrated belling/relay functions for shift changes or school periods. (Note: These are hardware-level options and should be specified at the time of order.)
