I'm going to cover the cameras at home while my mother is in thailand
Why would you need to cover the cameras? Are you hiding something?
She doesn't want me to see any porn.
It is understandable that you want some privacy when you are alone in the home even if you have to disable a home protection device. It would be better than your mom seeing you do that.
I have a right to some privacy.
Everyone has a right to privacy in their own home. As long as you uncover the cameras when your business is done, there is no harm in it. I am sure your mother doesn't want to see that anyway.
