How many cameras can be linked from the first one connected to the extender?

Officially, we can say 1 IPC linked from the camera. Power PoE, IEEE 802.3at(Class 4), 25.5W (DC OUT : 42.5-57V=, 0.3A MAX) DC OUT is extended port. 42.5V x 0.3A = 12.75W (min) 57V x 0.3A = 17.1W(Max) So, at least DC OUT (Extender port) can provide 12.75W~17.1W Basically, [...]
