We are developing a PoE powered device which should be connected between PoE switch and IP camera. I'm looking for an electronic engineer that can show me a device PoE splitter/extender/injector or some other device that could supply our device (please see in attached scheme ''MOUNTED DEVICE'') with 5V or 3.3V (approx. 2-3 Watts) and pass-through data and PoE to the IP camera. Our device will be connected via WiFi. The device that will split power and power and data should be small in size and cheap.
