I am interested to hear why the cameras give you peace of mind? I'd be curious to know what situation you imagine where these cameras help protect you or your family from any harm.
An event in which something happens and I have no record, such as robbery or violence within my home or neighborhood. It feels like the suburbs around us insulate themselves from crime. It gives me the feeling that if there are repetitive criminals in my neighborhood we might be able to track them down or prevent it from happening again.
The other day somebody sped through my neighborhood ignoring all red lights and lane markers. It would be cool to deter this behavior before somebody gets hurt. The police aren’t patrolling 24/7.
