Gigabit, Mode B 4Port PoE Injector without power supply: Power an IP camera, desktop phone, WiFi access point, or other low voltage devices through a network data cable using this Power over Ethernet (PoE) injector. The PoE Injector takes power from a DC power source (power supply sold separately) and adds it to your Ethernet data cable (Cat5, Cat5e, Cat6) to your device. Save big on network upgrades and device installations: Power over Ethernet delivers power 328 feet from the PoE Injector, eliminating the expense and hassle of installing AC power near your powered device. With this PoE Injector, you can add power to your data cable for a fraction of the cost of upgrading to a PoE capable network switch. Passive PoE means versatility: A Passive PoE injector always delivers the same voltage as its power source. Pair this injector with a 48 volt DC power supply to power devices labeled "802.3af", or you can use a 24 volt power supply with 24-volt passive PoE devices like Access Points from for Mikrotik, Ubiquiti, and many more.
