I'm very new to ip cameras and networking. I have two dahua ip cameras connected to my unmanaged poe switch. the switch is connected to my netgear router and PC. when i check my router for connected devices I only get one ip address for the cameras. so when I go to the web interface it shows one camera and then randomly switches to the other camera. they are sharing the same ip address which is not what I want correct? any guidance is appreciated.
