DEAR ABBY: My husband is addicted to our home security cameras. He, my 19-year-old daughter and I live in a townhouse, in which he has installed no fewer than 20 cameras in and around our home.

He’s always looking at them, when I’m on my way out to run errands or to visit my older daughter and even while we are eating dinner. He has started keeping a log of my daughter’s and my activities and what our neighbors are doing. What is wrong with him? — UNDER A MICROSCOPE IN CALIFORNIA

DEAR UNDER A MICROSCOPE: Does your husband have a job or any outside interests besides what you, your daughter and the neighbors are doing? His compulsion may be caused by insecurity, paranoia or a need to control.

Have you ASKED him why he feels the need to do this? While it’s not unusual for families to install security systems in their homes, your husband’s obsession is over the top. This isn’t normal behavior, and something may be wrong with him.
