Power over Ethernet (PoE)
Power over Ethernet, with its standard protocol defined by IEEE 802.3af specification,
delivers electrical power (DC voltage) over the same network cable of a device for
sending data traffic.
Certain models of D-link IP Cameras support Power over Ethernet (PoE) to provide
more flexibility and easier implementation of the IP camera without the need to worry
about finding a connection to nearest power supply.
PoE is especially useful for scenarios where power supply is not available or is
difficult to reach at the location where the IP Camera is to be installed.

With PoE support on the IP Camera, connection to power outlet is no longer needed. All that is
needed is for the IP camera to be connected to a Switch with PoE built-in.

802.11n
802.11n is a relatively new wireless networking standard that significantly
improves wireless network performance over previous standard (802.11a,
802.11b and 802.11g)
*802.11n is still in draft (version 2) and has not been ratified yet, so maximum range value may change
802.11n is released on June 2009 but has not been ratified yet although
many products have already use 802.11n standard. 802.11n is expected to
be approved in January 2010

WPS (Wi-Fi Protected Setup)
Wi-Fi Protected Setup™ is an optional certification program from the Wi-Fi
Alliance launched on January 2007 that is designed to ease the tasks of
configuring new wireless networks, adding new devices, setting up and
configuring security on wireless local area networks.
WPS allows users with minimal understanding of traditional Wi-Fi
configuration and security settings to configure new wireless networks, add
new devices, and enable security automatically.
D-Link WPS currently offers two easy setup solutions, PIN (Personal
Identification Number) and PBC (Push Button Configuration).
