disable plug and play support on your moden,
and go to the support page of your camera manufacturer and download the security fix,
last year it was shown that "most" cameras can be accessed from the web,
giving access through the firewall of some modems.
this is supposed to be easy to exploit,
so it could be that they used your cameras IP to access the rest of your network
better to be safe
