The DWL-P200 Power over Ethernet Adapter provides DC power to a network device, such as a wireless access point or Internet camera. The DWL-P200 can send power over a standard Cat5 Ethernet cable for distances up to 328 feet (100m). Using a single Ethernet cable that delivers both data and power eliminates the need to connect your Ethernet-enabled device directly into a power outlet. Power over Ethernet technology gives you greater freedom in device placement and easier cable management.
