Are You Running Twice As Much Cable As You Need?

Virtually all IP cameras have a single 100Mb Ethernet interface. Even current 4K cameras do not come with 1000Mb interfaces, AFAIK.

Yet 100Mbit Ethernet requires only 2 pair of 4. Even with POE, endspan switches prefer to use Alternative A, and put the power on the same as the data.

So, for longer runs that begin on a panel and terminate at a plate, servicing multiple clustered cameras, couldn't we get 2 cameras on one cable?

Maybe there are compelling reasons that we leave half the copper in the cable idle. Perhaps technical ones, like crosstalk, that make it ill advised? Or is it left for future expansion? If so, does anybody ever use the other half for another camera?

Is it ever a good idea?
