Electronic Clock System Product

1. Display Color: Multi-color LED display clock, P2.5, luminous point color: 1R1G1B;
2. Communication interface is RJ45, Ethernet time synchronization; compatible with wireless methods such as WIFI, LTE-4G, and IOT for time synchronization and management as per user requirements;
3. *Equipped with data security authentication, peer time synchronization, and management functions; the clock authenticates the time server via TCP/IP protocol. If authentication is successful, the clock can read the time from the time server; if authentication fails, the time server is deemed illegal and unsafe, and the clock cannot perform time synchronization;
4. *Supports three different time sources: (1) NTP time server synchronization; (2) Time and Information Management System software synchronization; (3) Both NTP time server and Time and Information Management System software synchronization;
5. *Features power on/off functionality, executing display and communication switch actions based on the set power on/off time;
6. *Equipped with countdown functionality, displaying normal time, countdown start time, countdown duration, and exam subject during the countdown period;
7. *Supports time and text information display functionality, allowing configuration of text content, display start and end times, display frequency, etc., via software;
8. Supports different time display modes, which can be configured or operated via remote control, including:
1) Year, month, day, hour, minute, second, day of the week + temperature and humidity;
2) Year, month, day, hour, minute, day of the week + temperature and humidity;
3) Year, month, day, hour, minute, second, day of the week + temperature and humidity + prompt message;
4) Exam display interface;
5) Recording and broadcasting display interface;
6) Countdown display interface;
9. Capable of normal time synchronization and other functions without relying on the Time and Information Management System software;
10. Features Ethernet configuration functionality, using dedicated software to configure local network parameters, time server IP, size, display mode, product category, etc.;
11. Supports display of exam instruction text information;
12. Allows configuration of display images and display areas via backend software;
13. Equipped with power-off memory function; in case of external power or network failure, the clock automatically switches to internal clock mode;
14. Brightness ≥600 cd/m², pixel pitch 2.5MM; minimum Chinese character display size ≥16*16 dots;
15. Viewing angle (2θ—) horizontal +140 degrees; vertical 45°/65°; driving method 1/16 (constant current drive);
16. The outer frame is made of black cold-rolled casing, one-time molding, acrylic panel, aesthetically pleasing and elegant. The clock face is treated with anti-glare coating, ensuring no reflection under fluorescent lights. All components are high-reliability, long-life parts, designed and manufactured for maintenance-free operation;
17. Independent timing accuracy: ≤±0.05 seconds/day;
18. Power supply: 220VAC±10%, 50Hz;
19. Environmental requirements: -15℃— +55℃, 10% — 95% RH;
