No security is guaranteed but if I was to install a CCTV system, I would use network switches or camera's from US, Taiwan or Euro based companies.
Showing a bit of security ignorance..

I'll give you a clue, just use a pi on the internal network to access and then remote in on a secured connection. you are then only locking down one machine for access to all. I get paranoid and force ssh. vpn, and locked ip access to name a few....
