This has caused me some grief because I couldn’t figure out what has been going on with my parent’s security cam setup. I have a dedicated computer there running blue iris. They cameras just stopped working a few times. Turns out everytime my father thinks the internet is slow he power cycles the modem/router. He does this by pushing the button on the powerbar that the POE injector switch is plugged into as well. I’m quite rusty on my networking. How do i prevent the IP addresses of the cameras from changing everytime the power is cut to the modem.
