Not directly Home Assistant related yet but this is the first step.
I am looking to install a Reolink POE doorbell and having very little network knowledge was unsure if there is a security risk having an ethernet cable running into the back of the doorbell. If someone were to remove the doorbell they would have access to the ethernet cable, could they then access devices and data on my network? Should there be any security steps I should take when installing security via ethernet outside?
For further information I have not decided yet if i’m using an nvr or a nas to record the video, I know i want it to be local and avoid the cloud, and I will certainly be running it through Home Assistant and want to receive the usual notifications and possibly run a few automations based on doorbell ring or presence detection.
Any network security help would be appreciated.
