digital signage GLOSSARY

PoE

PoE (Power over Ethernet) is a network standard that allows a single Ethernet cable to carry both data and electrical power to connected devices. PoE simplifies installation in digital signage scenarios by eliminating the need for separate power outlets near every device, and consolidates monitoring under network management.

Standard PoE variants deliver from 15W (PoE 802.3af) to 90W (PoE++ 802.3bt), sufficient for small to medium signage players, small displays, IP cameras, sensors, BLE beacons, NFC readers, and ePaper endpoints. Livesignage works with PoE-powered media players and sensors, and PoE integration is particularly natural in scenarios that mix signage with the broader smart-building or IoT infrastructure.

Use Cases

PoE-powered signage installations are particularly attractive in:

- Corporate environments: meeting room signage, ePaper room signs, sensor-driven displays.
- Retail and hospitality: small-format displays, electronic shelf labels, queue sensors.
- Healthcare: bedside displays, ward signage, nurse station monitors.
- Smart buildings: occupancy sensors paired with signage in shared infrastructure.
- Transportation interiors: ePaper transit info panels, bus and train signage.
