Should I spy on my kids?（2）

The moral issues come first. Using a security camera to monitor your kids is an extreme decision. You basically only control your own house, so you could install one in your kid's room. You should ask yourself first "is my kid really that bad?" The answer is probably no - but some kids will end up doing stupid things. If there's a serious risk to your kid's life or health, then you can feel much more comfortable doing it. The second thing to ask yourself is whether you actually have proof that your child has been engaging in something criminal or dangerous or whether you're just suspicious and want to install a camera to catch them. Suspicion alone is probably not a good reason to stick a hidden camera in your child's room. All parents have these suspicions from time to time - but if you're wrong, you've just eliminated your child's privacy on a whim. They are people too, and while you're the parent, you also have to show them respect and care for their rights as a human being. It can be a different story if you actually know that your child has been doing something. It's hard to make the case that you are unfairly refusing to trust your child if you've already caught them red-handed with drugs, or if they've been arrested for them. In that case, they have violated your trust - and it is not unreasonable to think they might do it again.
