StarTech.com 1 Port Gigabit PoE+ Extender 802.3at & 802.3af - 100m (330ft) - Power over Ethernet Extender - PoE Repeater Network Extender (POEEXT1GAT) - repeater - 10Mb LAN, 100Mb LAN, 1GbE

Scale your Power over Ethernet connection by 100m, or daisy chain up to four extenders for longer distance. This Gigabit PoE+ extender spans your Power over Ethernet (PoE) device over longer distances, letting you double the 100m limitations of a traditional PoE infrastructure.
Now you can connect your Gigabit PoE device up to a maximum of 200m away, so it's easy to install a remote IP camera or access point. Plus the extender can be daisy-chained for more scalability.
Need more distance? This convenient PoE+ repeater maximizes range and flexibility by extending your PoE connection by an extra 100m (330ft), while providing 24-watt power output to compatible devices.
Simply connect the extender to your power sourcing equipment (PSE) and your PoE-powered device (PD) and you're all set. The extender is compliant with the 802.3at/af standard, so it will work with existing PSE, such as a StarTech.com POEINJ1G PoE+ injector (POEINJ1G) or IES81000POE PoE+ switch (IES81000POE).
Still need more distance? If an extra 100m isn't enough, this full-featured PoE extender offers daisy chain capability.
You can easily connect four extenders together, letting you install your PoE+ PD up to 500m (1640ft) away. It's perfect for business, education, and retail environments (output wattage is dependent on the number of daisy-chained extenders used).
Get up and running quickly. This Gigabit PoE+ extender can be positioned right where you need it, with a wall-mountable design that requires no external power adapter.
You can enjoy reliable performance with little worry of downtime or failure, the extender features a rugged metal housing with built-in ESD and surge protection.
