One of the reasons I go camping is to escape the rat race.
Installing cameras amounts to bringing the worries and burdens of the rat race with me.
No thanks. I prefer to be worry free. I 'm not really concerned as to who or what maybe lurking outside of my RV.
I'm not naïve enough to believe bad guys don't exist. But if a bad guy shows up I'll deal with it then.
In the meantime I don't need to worry or create any imaginary scenarios that require a camera to give me peace of mind.
Currently I have no issues escaping the rat race no cameras required.
