Power over Ethernet (PoE) Brings More Functionality to Tablet Enclosures
Power over Ethernet (PoE) is emerging as an important safety and functionality factor for businesses using permanent AV displays and interactive POS displays.
What is PoE?
PoE is a relatively new technology that allows electrical power and data to pass through CAT 5 Ethernet cabling and LAN infrastructure without the need to make modifications to it. In other words, PoE is competing with USB cables and Firewire to power AV devices such as iPads and Tablets.
PoE Technical Information
PoE technology is regulated in a standard known as IEEE 802.3af and is designed to ensure that data communication performance is not hindered. Power is delivered over an existing LAN infrastructure and is automatically activated when a compatible terminal us identified.
What are the Benefits of PoE?
Unlike USB cables which have a maximum length of 5m / 16ft and provide 2.5 watts of non-isolated power, PoE can be implemented in long cables of 100m (330ft) and deliver 12 watts of galvanically isolated power. This is ideal for businesses that use interactive POS displays such as Tablet Enclosures to encourage customer interaction, as PoE gives them the freedom of increased mobility as the display can be mounted 100m away from a power sauce. Users also benefit from increased security, cost savings and simple installation. Furthermore, PoE provides power and data connections through one cable which is a safer alternative to USB as there is no AC power involved.
Commercial Use of PoE
The following devices are compatible with PoE technology:
- Permanent and Remote Point of Sale (POS) Kiosks
- Tablet / iPad Enclosures
- IP Security Cameras
- VoIP Telephones
- Wireless Access Points
- Lighting Controllers
- Access Control and Help-Points (ie. intercoms & keyless entry systems)
- Outdoor Radios with integrated antennas
