I think I may need to correct some of the information I was expanding on earlier, as I did not realize that the “original stickup cam” was still available (which is such a relief). the introduction of a PoE injector can be a pretty expensive proposition if you are looking at more than 4 cams, whereas a 12 port PoE switch would be about the same cost or just a little more to add to your network. By adding the PoE switch you get all the control of these devices (at least from a data perspective) to monitor flow and congestion. With the injector’s you just get power added, but nothing else. I don’t see any white papers on these injector’s so I don’t know if there is any ability to manage them via the connected network.
