Hi team , newbie to all things cameras have a couple of questions, setting up the house with nvr ,modem, router. Have a pole that s 80metres away line of sight that has power , was needing to mount 3, 4k ip cameras on the pole cannot trench back to the house due to rock , what's the best way to send this signal back to the house, will one ethernet bridge handle three 4k cameras , also do I need two aps or can the router be one , also what would the wiring be for the camera pole do the three camera's go directly into a poe injector ... Thanks for any info
