Schoolguard
School Emergency Reporting System
In case of emergency, report your circumstances to the teachers’ office simply by pressing a button on your remote control! This is an innovative security system that enables users to confirm the classroom number in question at the teachers’ office to take immediate action!
EQguard
Earthquake Early Warnings save lives and protect property.
This system saves lives and protects property from earthquake damage by notifying the user of the seismic intensity level seconds before the arrival of the strong secondary tremors during quakes, using audio and light signals to communicate Earthquake Early Warning announcements from the Japan Meteorological Agency.
Self-Locking System
Wireless Self-Locking System for Apartment Buildings
Security System for Buildings
Since this system runs on a wireless basis, wiring installation in rooms is unnecessary! Our Wireless Self-Locking System only allows people who have been admitted to enter the building to pass the entrance door and automatically locks that door once they have done so. Tenants can operate the system with a small cordless phone device that can be carried around with them in all apartments and shared spaces within the building.
