True or not? Thermal cameras can detect gas being let off?

THERMAL cameras have become commonplace at border points throughout the world to detect travellers with high fever and for other reasons. And they are effective – sometimes with embarrassing consequences.

STOMPer SnakeEyes received this video via email showing how a thermal camera can detect even the letting off of gas from a human body. He’s not convinced this really happens. SnakeEyes thinks it’s a hoax but if this were the case, then the imaging is very well done.

In an email to STOMP today (Aug 24), the STOMPer says:

“Although thermal cameras have been removed from Changi Airport, they are still being used by hospitals at their main entrances. So, the next time, you visit a relative or friend at the hospitals here, don’t let off gas, thinking it’s undetectable. You may just be on candid thermal camera!”
