I watch a poster "Do not miss it! That violence is a crime!"

A organization of private railroad company started posting it all at once, I just reconfirmed that.

I am engaged in research on video surveillance systems,

"After all, it a matter of time isn't it?"

(Please refer to the item of "For my video data transfer experiment" on this page)

Of course, I have no opinion on the contents of this poster.

Regarding privacy issues, even with the police and judicial checking system, I think that I have no problem.

The Supreme Court also makes the same judgement as I am.

In 2007, London has installed 4.2 million cameras in the city, and tourists are photographed in security cameras almost 300 times a day.

And they succeeded in surprisingly sharply reducing the number of crimes.

The price of surveillance cameras has dropped to 0.5% (1/200) on the basis of around 1990.

It is no longer possible to deny system installation due to the cost of surveillance cameras.

Now, The cost of installation and operation may be cheaper than installing a PC.

I have insisted on many times from before -

If we want to solve the problem of "bullying" seriously, we can install surveillance cameras everywhere in the school.
