Extending Ethernet capabilities

Hailed as a watershed innovation when first standardized in 2003, Power over Ethernet (PoE) offers a way of supplying electricity to network devices over standard Ethernet data cables. A convenient and affordable way to power up network devices such as wireless access points and security cameras, PoE eliminates the need for separate electrical power lines to each device.

Using already existing Ethernet cables for transferring not only data and voice but electrical power as well, greatly reduces installation and maintenance costs associated with security installations.

Ethernet capabilitiesCoupled with the booming demand for security monitoring worldwide, the freedom granted by PoE has made cameras appear in every conceivable location. In addition to cameras, the market for access systems, RFID tracking, biometric identification, fire detectors and other security equipment continues to expand, benefitting from the PoE technology.

The drawback, however, of more and more sophisticated security devices is that these require more power than the existing PoE standard is able to provide. Therefore, work is underway to standardize the next version of PoE, called PoE Plus.

Speakers, heaters that prevent moisture build-up and door-lock supplies are other power-heavy features soon within reach. In addition, more power may further facilitate access control by being able to power mechanical door openers.

If looking ahead there is a huge, untapped potential for PoE in the residential market, saying that the entire home may rely on PoE for access control, security, locks, cameras, WLAN, modems, even indoor lighting, as solid-state lighting powered by PoE is on its way.
