In the late 1800s, the famed scientist Nikola Tesla imagined a future entirely free of cables and wires. He imagined a world where we’d be living in a paradise of free energy, broadcast wirelessly through the air. Of course, these ideas didn’t sit well with other innovators working at the time, who suppressed Tesla’s work, which is finally getting a fair analysis.

Part of the reason for Tesla’s newfound popularity is the availability of wireless technology. This is partially due to innovative new technology, like Bluetooth and Wifi, which would have looked like hard science fiction, even as recently as the mid-90s.

Now that we’ve seen what can be accomplished wirelessly, we’ve becoming addicted to clean, wireless configurations. Not only are wireless networks quicker and easier to set up, they can also save substantial amounts of money on engineers and electricians.

One popular wire-saving technology is a 9 Port PoE Switch.

A 9 Port PoE Switch, like this TP-LINK TL-SF1008P 10/100Mbps 8-Port PoE Switch, 4 POE ports, IEEE 802.3af, 53W, stands for Power Over Ethernet. 9 Port PoE Switches remove the need for external power cables, by sending an electrical current through the braided ethernet wires. PoE Ethernet switches are lightning-quick, while still being clean, minimal, and efficient, by eliminating the need for dedicated power plugs and spools of tangled wires.

One of the most popular applications for 9 port PoE switches is for surveillance systems. The Koolertron Networking 9-Port PoE Switch is a great choice for surveillance systems, supporting up to eight cameras, eliminating the need for dedicated power supplies in the process, while also streaming to a central server, for easy monitoring and data backup.

Get rid of all of those tangles and clusters of cables, and hefty electrician bills, by using 9 port PoE switches.
