Sorry for bad drawing. Took over a warehouse, had existing ethernet cables (PoE for existing DVR cameras, quite old). Each distance is at 120 - 160ft ft or so. A-site is nearest power outlet with an existing Cat6 ethernet line, which voltage and adapter? B-site is the attic where I would like to put my Mofi4500 LTE router up there, best signal, so needed to get a PoE splitter 12v. C-site is where my desktop runs over cat6 ethernet & ethernet payment processor, there is power outlet in this room. D & E-sites are locations of the Wyze cams, must be powered by PoE splitter (which voltage?)
Please give me a few ideas of which amazon product to buy in order to get this started.
Can I get data at A-site for a backup external hard drive & receive data back from the LTE router by B -site utilizing the same cable? If not, I’ll bring the external backup hard drive to connect to the desktop at C-site.
