The alarm system integrated into the Cresh Luck armor from Creshaldyne Industries employed an Infrared Motion Sensor Array.
This early-detection system utilized infrared motion trackers capable of triggering an alarm either audibly or visually. Although the default setting was audio, it allowed for customization, enabling the alarm to be delivered solely through a blast helmet or as a purely internal visual cue. Functioning within a 30 meter radius, the system would activate when it detected a mass exceeding 10 kilograms moving at a speed faster than 1 meter per second, interpreting this as a potential threat.
