Summary: So am helping a friend put in a security camera system in his shop and we have 4 outside cameras. Instead of getting a $300 electrician to run power to them, I decided to run the cameras via PoE. I went here saw that this device was rated well and lots of good helpful reviews so I went with this device. After getting everything all setup I plugged in the cables and only one camera worked. I power cycled the switch and again only one camera came up.
Summary: Got this for a new install of 4 POE IP Cams, it is working as expected. Was factory sealed, all parts where as indicated, and in the box. I got 2x TP-LINK TL-POE200 Power over Ethernet Adapter Kit, 1 Injector, 1 Splitter, up to 100 meters (325 Feet), 12/9/5V power output in addition for some older Foscam I have, though I have not been able to fully test yet.
Summary: I used this to power 2 Dahua 1.3 Megapixel 12V PoE cameras. To the best of my knowledge the device worked properly 24x7 for about 5 months. Then, no POE. Still works as a hub, but I bought this specifically for the cameras and have had to replace it. I swapped out this switch leaving the cameras and cables in place and they came right back on line, so I know it was this unit that failed.
Summary: Not terribly impressed with this POE switch. No wall mount slots on the back/bottom, so it has to live on a shelf, making it difficult to conceal and keep cool. So the ugly case and nine wires extending from the back (8 Ethernet & 1 power cord) makes for a hideous eyesore. The good part is the switch does what it's supposed to do.
Summary: Switch works great to power some huacam IP cameras. I am only using 2 cameras so I can not say how well the unit handles a full 50 watt load on it, will be getting 2 more IP cameras though. Only thing I wish was different on this switch is a couple of mounting holes in the back.
