IP CCTV and network security

[Heres Johnny]

I've a few IP cameras but it's occurred to me that also means I've a few CAT5 cables protruding through exterior walls which if someone was minded to, they could simply unplug a camera and plug in a laptop and get into my home network. Chances are small, but how am I meant to protect against it? The hub they're plugged into is an unmanaged one, but even if it was, that manufacturer suggests mac filtering but that appears universal and I'd need to constantly register new kit. Ideally I'd like to tie specific ports to specific mac addresses and the kit I have nosy not be adequate, but I'm curious to know what the options are.

Stick the IP Cameras all on a separate LAN?

Unfortunately they record to my NAS

I'll look at SSH but not sure how that helps me.

Thanks - agree the risk is small but where I live and where the cameras are you could sit in my open garage and help yourself as it currently standards. I've just spent too many days with CLAS consultants in my past

All default passwords have been changed and I've now dropped the ddns so I can't access the cameras remotely. I think I'm going to opt for the mechanical locking route. The cameras are hikvision and they all have short tails with a socket on the end so plenty of options to secure. Sometimes the simplest ideas are the best

How bad an area do you live in to need to go to this level? Or are you really James Bond?

Its actually really quiet, middle of the countryside, we get very little crime and the original question was as much a curiosity, but I'm worried about my sordid collection of Pam Ewing and Wonder Woman pictures from my childhood being held to ransom
