Nature Alarm!

Alarm device which install a tree and transfer victim's face and voice. It' made for high schhol students.

One of sidewalk problem is user's feeling insecure because some part of the way is not enough light, some too dark. This case we studied at sidewalk around 3 king statue of Chaing mai where nearby high school and many students use this route to go to tutor at 6-8 p.m. 5 daye a week or more. They usually feel insecure when walk alone. So we create this innovation to protect them and it's lighting also. This device install a tree when you press for 5 sec. video and voice are transfered to police station!! "Nature Alarm" can recharge itself by 1. Solar cell above the tree 2.Press frequently to store energy so it always work unless electric broken!!:)
