Hi I've started looking into a home camera system and have come across this thread. I have a similar situation. My garage is also detached from my house. I was led to believe that the each camera had to be plugged into the NVR separately and directly. Is this not the case? From looking at this thread it looks like your plugging in 2 cameras from the garage into a POE switch then basically connecting that POE switch to the router. Is this the correct? If so this would make it much easier for me.

I would have the same but the POE switch in the garage would connect to my router via a cat6 cable that is running between the house and the garage
