Have you seen a strange woman in her late 50's prowling around your neighborhood uninvited?
1)In-home security cameras that are HIDDEN and are NOT part of a cable TV provider package or your cellphone provider
With technology as it is today you can get security that isn't on a bill. It's best to be ULTRA private about where and how you capture images on camera in your home.
2)Valuables? Where does one put them?
---multiple safety deposit boxes at multiple banks, and storage that is under double lock and key (the storage facility, which has cameras, and your own key.)
Keep all valuable OUT of your home, especially when you have caught the lurkers in the act.
