Oh my! I can't get drunk in your house. If I puke or pee outside, I will be seen(and worse recorded). LOL! Your shelter is rigged with equipment for security which is indeed a translation of your husband's love.

There may come a time that the motion sensors installed will be so advanced that any sign of threat will automatically lockdown your house. Have your husband considered also defensive security protocol?..haha

To answer your question, I would say "yes, it is necessary." It is better to overprotect than to be vulnerable.
