Since most camera flashes emit IR along with their burst of visible light, the one substitution allowed the prototype to transmit and record infrared light.
由于大多数相机闪光灯在发出可见光同时就会发射出红外线，这一替换使得原型机能够发送并记录红外线。

These include enhanced emission of infrared (IR) radiation from the earthquake epicentre, as well as anomalies in low-frequency electric and magnetic
