Need to power a device over an Ethernet cable but your router or switch doesn't have PoE? This passive PoE injector is the solution. It's a simple, unbranded unit (model POE100) that sends DC power (from 12V up to 48V, depending on your power adapter) over the Ethernet wires to devices like IP security cameras, VoIP phones, or wireless access points that support passive PoE. Important: This is PASSIVE PoE, not the smarter 802.3af/at standard—make sure your device is compatible. Installation is easy: connect the injector to your network and plug in a compatible DC power supply (not included). No configuration needed. Perfect for home security setups, small office networks, or DIY projects. It's a cost-effective way to add PoE without upgrading your whole network gear. No MPN or UPC, but it's a straightforward, reliable little device. Just double-check your device's voltage and pinout requirements before buying!
