the "PoE" in the trendnet descript refers to Power over Ethernet - in other words the power is going thru the ethernet cable - makes it easier to send power that way vs having to put a power source, ie a 110V box at each camera. And don't even waste your time thinking about those rechargeable battery power cameras, like Arlo - they claim 6-9 months usage per charge, but what they're not telling you is that quote is good if you're only having the camera transmit on motion events - i prefer 24/7 recording streams
plus, ethernet cable is more reliable and more secure than a wifi signal
The Trendnet PoE port supplies 48V, which the PoE device, in this case the camera, will regulate down to the voltage it needs. The reason the PoE port transmits 48V, the higher the voltage, the smaller the guage the cable has to be to deliver current to the end using device. I learned this when i looked into putting up solar panels at the back of my property - i thought i could put the batteries in the basement but soon found out to deliver the current the panels would be putting out at 12V, i'd need cables as big as my thumb, where as if i built a shed back where the panels were for the batteries and the inverter, i could run much smaller guage wire to deliver 120V to the house
