    Long-range IP camera networking options

    I already have grid power available at all remote sites, so power isn’t an issue. However, as you mentioned, the terrain isn’t clear line-of-sight — there are trees and some buildings in between. Do you think a wireless PtP solution is still feasible in this case without running fiber?

    Managed PoE switches randomly lose port power/signals

    Hi everyone, I’m having an intermittent issue with two PoE switches (each 16 ports, used to power IP cameras). Case 1: Sometimes, one PoE port suddenly loses both power and network link. When I move the cable to another port, it works normally. Case 2: On another switch (same 16-port model), all...
