Can you really beat those body heat sensors?

Talk about it here!

MythMod

On the show Tory Grant and Kari discussed is it possible to beat thermal sensors like in the movie Predator. One factor they forgot to look at is Arnold fell into water before being covered in mud which lowered his ( Arnold's body temperature ) where Tory was only covered in mud.

Also, in the Predator movie Arnold was a chain smoker... now I don't know if Tory smokes and if he does how long he has... but a smoker's body temperature takes much longer to raise than one of a non-smoker, so if the smoking Arnold did fall into freezing cold water and then covered himself in mud he would stay colder much longer than someone else might

You are missing a huge point.

Heat dectors sense heat that is "strange" to the air around it.

So if your body is running at 98 degrees, and the air is 75 degrees...you will be detected.

So unless you can get your body tempeture down to 75 degrees you will be detetced by a heat sensor.

Unless of course you are outside and it is above 98 degrees.

(75 degrees is probably the AVERAGE degrees for an AVERAGE office space) its probably be colder which means it would be harder. It all depends on the heat detector.

I think the point they made is that heat detectors are beatable,
as long as there exist one method that is reliable and easily
put to practice, it should be good enough. Clearly, they showed this with the glass plate in front of the heat sensor. It's so easy it makes all other ways of trying to beat the sensors meaningless.

Good job for the team!

But, I think the ultrasound alarm they were using in the same episode was crap. They need to get one that's better designed and have more secure features.

Was the thermal sensor defeated because of the reflectivity of the glass and the sheet? I wonder if a Mylar bag/covering would work too?
