What it is for
Rated for 24/7 use with a 50,000 hour life, so one line serves both meeting rooms and signage.
- Stays on the network in standby (Network Ready, Wake On LAN), with SNMP and LG Business Cloud for fleet management.
- A second manufacturer in the standard, so a supply problem with one does not stop a project.
