There are villains who work under cover of night, and then there are villains who hide out in plain sight.
It’s important to remember that people always act differently when no one is watching them. There is a face that people show to the public, and a face people wear when they are alone. Horrible people can act charming and charismatic at the drop of a hat. This is exactly why you should always have a way to keep tabs on your home when you allow other people inside.
If you ever have to hire a babysitter, you would want them to take care of your children and make sure they are always safe. If you ever hire a repairman, you would want them to do their job with diligence and competence. Unfortunately when hiring these people, it is difficult to tell if they will truly accomplish what they promised you.
There are two common approaches to monitoring your home. The first approach is to have a large and obvious surveillance system, complete with cameras watching rooms from a corner. The second approach is the subtle approach, with hidden cameras and nanny cams in disguise around the house. Both methods have their advantages and disadvantages.
Obvious surveillance systems serve strongly as a symbol or reminder. Once a person knows that they are being watched, they start to behave as they would under the public eye. It is not as effective as watching people in person, but the implications of being caught doing something inappropriate is usually enough to keep people behaving. The presence of a surveillance camera outside your home is also able to scare away potential burglars.
Hidden cameras don’t have the same psychological effect as obvious surveillance, but they are useful for testing the character of people. People truly act like themselves when they don’t know they are being watched. If a person is pleasant and attentive when they don’t know they are being watched, then you know that they are naturally favorable.
Trust between people is not a bad thing. Trust is essential to many aspects of society. You just have to be realistic about the possibility that some people aren’t what they seem. You may not have to worry about that as much in the outside world, but safety is a high priority for your family and for your home.
