The other day, I wrote that I had been to my wife's country house in Kagoshima prefecture to install the home security system (presented by me).
Before flying to Kagoshima, I have installed "The Kagoshima system" in my house, and tried to check the system beforehand.
"It is system that cannot run in the field, in spite of prefect preparation."
I have experimented a lot of the above case for my engineer life.
On the other hand, I started the Ebata's Home security system, too with fully functions,
in order to check the difference between "Kagoshima System" and "The Ebata's System".

I tried to restart a monitoring device, left alone outdoor nearly three years.
I have disconnected the device from the network, because I thought it doesn't work well naturally.
However, when I connected it to a host computer with the network, the red LED started blinking and changed green soon, that meant "reboot completion", so I was really surprised to watch it.
When I checked the system status from the host computer, I could find a device not to see usually.
I sent a control message to the device,
The device answered.
Accurately, regularly, same as three years ago.
