Hi, The design is that there will be 6 ip cameras in series and only 1 utp cable will come in at home. There is also a DC power supply outside. it's not my design and I'm not convinced by the system. Only the piles and the power cable come out. How can this system work? What principle is it based on? I think it's just a matter of how they want to work. I want to use ip poe cams myself.
