Active Evacuation Guide System increases the chance of survival in case of emergency.


A Passive Evacuation System too limited to protect human lives

Key Issues
  • People spend 70-80% of their time in large buildings, increased complexity
  • Since 2013, terrorist attacks increased 3.5 times → increased anxiety and fear
  • Intelligence of adult = infant in case of emergency
  • Lack of protection for safety personnel and risk
  • Disaster/terrorism causes loss of human lives
    (2,065 people suffered from disasters over the past 10 years)
  • Disruption results in more damage
  • Lack of timely response
    (Delay in initial stage → affects chances of survival)
  • Awareness of emergency evacuation remains at 38%
  • Safety personnel and rescue teams are not protected


Active Safety Agent is a key to protect safety managers

Virtual Agent System

Real-time On-site Support Algorithm

(In→Out Evacuation, Out→In Search & Rescue)


Corners enables a more efficient, timely response to disasters and terrorism.

Service Operation Platform

for real-time evacuation analysis, information and control

Stations located in the building monitors the status of LoRa Gateway

  • Station power supply, sensor data, battery condition and communication status
  • Gateway power supply and communication status

Temperature and gas sensors detect events

  • Station’s built-in temperature and gas sensors detect events and trigger alarm
  • The monitoring screen changes its color when an event is detected
  • Check the station’s event alerts (temperature and gas sensor data)

Trigger pop-up alert when the server communication with LoRa Gateway is disabled

Activate automatic evacuation guide when the station detects an event

Manually activate evacuation

  • The manager triggers event manually on the station
  • Activate manual evacuation (immediate evacuation)
