Hello,
I have an application that uses 4 cameras PoE. I have one PoE switch in a cabinet in a server room while Cameras are outdoor at different locations. The closest camera is at distance about 80m (that is the cable length), while the furthest camera is about 160 meters. For sure, three cameras are more than 100 m from the switch in cable length. Voltage level is about 48VDC (that PoE switch is supplying.
Since PoE is working reliably up to 100 meters, obviously I neeed to use some kind of PoE extenders. In order have two options:
1. To buy 4 outdoor PoE extenders, like this one ( DIGITUS Outdoor PoE Extender - 10/100 Mbps - 100 m Range - Protection Class IP67)
2. To buy 2 Outdoor PoE 2-ports extenders, like this one( FASTCABLING Industrial Outdoor PoE Extender 2 Port, Repeat 328ft PoE for Mesh, PTZ Cameras). This would save some cables
The thing that is strange to me is that these extenders doesn't require any external power supply, so I'm not sure how they're boosting signals. How these extenders really works and the my question is whether I need a different type of extender, one with auxiliary power supply.
Thank you for your advices.
