Controlling port with another port.

Hello Mikrotik community.

I would like to know if this can be done and how.
I have CRS328-24P-4S+RM for ip cameras. I would like to install some of cameras also inside home, but they should be working only when I’ m not at home and home locked/secured.
At the moment I have installed one Hikvision camera and powering it with regular 12V and controlling it with relay witch is switched when home is locked/secured.

Looking to install 3-4 more cameras and now I have question.
Is there a possibility to turn these extra cameras only when that one camera is on and port link is up and when link is down, also other will be off.
It doesn’ t have to kill PoE, if it can be done somehow stopping traffic from camera, it would be OK.

I really appreciate it if someone could help.

While there is doubtless a way to produce a spit-and-baling-wire solution using nothing but RouterOS, this problem has Home Assistant written all over it.
