PoE is a technology that works well for wireless access points, video surveillance, building management, retail video kiosks, smart signs, and retail point-of-information systems, making it possible to easily move a device with minimal disruption. Additionally, if your LAN is protected from owner failure by a UPS, the PoE devices connected to your LAN are also protected from power failure.
Using Power over Ethernet can save hundreds of dollars per Wi-Fi access point (AP) locations compared to a non-PoE solution.
In a non-PoE installation, in addition to the Ethernet backhaul link, power must be wired to the access point. Depending on factors such as AP location, distance from the AC circuit, and local safety codes, the savings from using a PoE solution can be $250-$500 per AP. In harsh, outdoor, or industrial environments, you can save $750-$1500 per AP by using Power over Ethernet.
PoE Mid-Span Injectors add power to Ethernet for powering PoE powered devices ranging from wireless access points to IP cameras. PoE enables you to easily move equipment from room to room without costly, time-consuming rewiring.
Power over Ethernet is also the answer if you’re doing a high-density phone conversion from keyed phones to VoIP phones. There’s a much lower installation cost—all you need to do is provide the Ethernet connection. We have a variety of PoE PSE equipment including switches,media converters, and injectors.
Plus, using PoE can improve VoIP phone system availability. Power over Ethernet PSE gear can be located in data centers with uninterruptible power supplies and battery backup. This arrangement means that your PD VoIP phones will remain working if there’s a power failure. On the other hand, wall-powered phones will stop working when the power goes out.
