I suppose next you people are going to go on a rant against web-enabled Nanny Cams.
Very similar application in principle.
$100 GPS or a $600+ laptop. If you REALLY want to get into expenses, why was the school sending these expensive pieces of equipment home anyway. In fact, why have they invested in them to begin with.
There is NO excuse for a government agency to have the ability to take a picture of ANYONE in the privacy of their home. Period.
Similar technology but completely different legal situation. I am not a lawyer so I can only give my layman's opinion:
You have a perfect right, as a private individual, to have video going in your own house. If others come into your house they may be captured on video. You will need a lawyer to say whether you have to warn the nanny or not.
A public, government entitiy like a school has a right to the information about where that property is but they do not have a right to invade the privacy of any individual *off* of school property by videotaping (or audiotaping, or recording in any way) the person's private life, surroundings, activities, body, conversations, or anything else.
Cost has ABSOLUTELY nothing to do with it. The Constitution is not sold out to the cheapest technological solution.
