EDL-Emergency Door Lock alerts the outside world and notifies responders of emergencies in the home. With the rise in single-person households and the high risk of falls among the elderly, EDL detects emergencies via voice control or camera monitoring after receiving a call for help. The lock features three color modes: black, orange, and red, indicating different danger levels and flashing to attract attention and notify responders. EDL also unlocks and notifies during earthquakes, fires, and other emergencies. EDL ensures easy observation, providing a means to seek help in enclosed spaces.
