Looks like spam to me carolfische, first post I notice, that link has nothing to do with what this topic is about.
Monitoring systems can have a great role to play in our lives, though I would suggest we not become too dependant upon them.
I can tell you carolfische, it does not make me feel safe at all, and am curious to hear why you would think that.
For the most, they help pass the time and give some joy as well as frustration, not a feeling of safety.
For others reading, the original poster and I have been in private email contact to discuss further his project.
