Once connected to your network, the clock automatically synchronizes to your NTP/SNTP server for reliable time accuracy. It supports up to 5 SNTP servers for redundancy, ensuring stable time sync even in demanding enterprise networks.
Designed for simple deployment, the clock runs on PoE—reducing wiring complexity and avoiding the need for nearby electrical outlets. Ideal for new builds and retrofit projects.
The HH:MM:SS layout is perfect for environments where seconds matter—such as healthcare, production lines, transportation hubs, and security facilities.
Supports 12/24-hour format, Daylight Saving Time, and offers adjustable brightness to match different lighting conditions.
Application Scenario
The synchronized PoE time clock is widely used in six fields:
Q: Simple Explanation How This SP200 PoE Digital Clock Works
A: Plug the clock into a PoE switch (or PoE injector). Set the NTP/SNTP server in the configuration tool. The PoE Digital Clock automatically synchronizes time and keeps your facility’s clocks consistent, no manual setting needed.
Q: Does the SP200 PoE Digital Clock require a master clock to keep accurate time?
A: No. It synchronizes automatically through NTP/SNTP servers, so no master clock is needed.
Q: How is the SP200 PoE digital clock powered?
A: It's powered through Power over Ethernet (PoE). The 12V DC power is optional.
Q: What information can the SP200 PoE digital clock display?
A: It displays hours, minutes and seconds.
Q: Does the SP200 PoE digital clock support 12/24-hour formats and Daylight Saving Time?
A: Yes. Both 12/24-hour modes and DST adjustment are supported.
Q: What network settings are available?
A: The PoE digital clock supports DHCP or Static IP and can connect to up to 5 SNTP servers for redundancy.
