I have 6 poe IP cameras around my house that run into a poe switch that is outside in a weather tight box which is powered with a extension cord outside then it has a single CAT5e cable that runs inside my house to my switch. I also have a detached garage about 50 ft from the house. The garage has another poe switch inside with a single CAT5e cable running back to inside my house underground. I've been using blue iris to monitor things but have wanted to switch to a NVR box. I didn't really set this up for security obviously someone could just un-plug the extension cord to cut off the house cameras. I would like to fix this but not sure how. My only idea is to run new CAT6 cable to each camera underground back into my house where a poe switch would be but that would be a lot of work, It would require going into a crawl space, lots of digging and drywall cutting.

Okay but if you have say 12 cams you still need a 12 port NVR even though you will only be using one port right? Thanks for your help. If you're worried about someone cutting power to your cams have you thought of putting a UPS to give you redundancy for your cameras ? I use a 4500 watt UPS that i picked up at the right price to give backup power to my entire system and i get over 3 hours . I have thought about that but there is no where to put it outside plus it's exposed to the heat/cold.

CPU usage is around 70% that's also with me on youtube etc To clarify i can run one cat5 cable to a NVR and it will see all the ip cams i have? I was under the impression that to use a NVR each camera would need it's own cat5 cable run separately directly to a NVR.

What OS are you using? And what software? I even lower each cams setting to 10fps and a low bit rate, i also use the same PC to surf the web. BTW if i bought a NVR and only ran one CAT5 cable to it would it be able to see all the cams i have that are powered by my poe switch?

A i5-4670K mini pc that i built. Cameras are 3MP Dahua and Hikvision. I have one Dahua PTZ and 12 Hikvision cameras,

Thanks for the input, i could put it in PVC even if someone did un-plug it they are seen on camera before hand. I wish i could get away from using my PC to see the cams it takes a decent PC to run 12 1080p cams. How does a NVR box handle cams so easy?
