As a matter of fact, my router password and username are both admin. Also, my security camera system login and password is by default 888888. It doesn't really matter since like bob123 said you can't access them from outside the local network. I could technically allow my cameras to go online by opening ports on my router, but I have no need for that. You should really be more concerned by your wifi, since every kid these days knows what a packet sniffer is and how to use it. Weak wifi password can compromise your whole setup in an instant.
