Embedded Content & Group Management


Embedded Content & Group Management

The embedded Content and Group Management System allows you to edit and play content, schedule playlists and groups, and control Signage via remote control, mouse and mobile phone without the use of separate PC or software. This makes content management much easier and more user-friendly.
SuperSign Control


SuperSign Control

SuperSign Control is the basic control software, and it can manage up to 100 displays through a single account and server. Power, volume, and scheduling can be remotely adjusted, and firmware updates supported.
USB Data Cloning


USB Data Cloning

USB data cloning increases efficiency in managing multiple displays for optimal operation since users don’t have to set up each display one by one. Once users copy data to a USB device in one display, it can be easily distributed to the other displays through a USB plug-in.


Real-Time Remote Monitoring
Malfunctions or errors can be easily handled through real-time remote care. When an error occurs, notifications can be sent through the SNMP (Simple Network Management Protocol) protocol.

WOL (Wake-on-LAN) enables users to send a message throughout the network to power on displays.
Perfect Picture Quality and Color
