Advanced network display - digital clock

NT-250 is a network display designed as digital clock, which is basically used in working time registration systems to displays the exact time when employees come in or out. It is advanced version of NT-240, having in addition an ambient light sensor for automatic brightness adjustment, as well high-accuracy onboard hardware clock. The device can be used as stand alone clock or in conjunction with a remote server. Additionally, the local onboard clock is synchronized every night over external NTP server and can be used as a fallback clock source if the connection with the remote server gets lost. The two flashing dots can be disabled, allowing the device to displays other numerical information if needed. With a custom software application, this device can display any suited information like time remaining or time elapsed, counter values, etc.
