For screen sizes up to 27 inches, power can be supplied via PoE. PoE combines power and data connections into a single cable, simplifying installation and reducing costs. It enables remote management through managed switches, allowing devices to be reset, reconfigured, or updated remotely, minimizing downtime and simplifying maintenance. PoE complies with safety standards by using low-voltage cables, reducing the risk of incidents. Additionally, PoE provides a reliable power supply and enables scalable expansions without complex wiring, offering flexibility and cost savings when integrating screens in elevators and other applications.
