I did once manage to see where my oven (cooking my dinner at the time !) was as it had heated the outside of a filled cavity brick wall just enough (0.2 degrees F say) and it was around freezing outside. That was with a fairly standard thermal imager (not a seeker).

Gives you some idea.

As Ryan says you do not see through anything solid (OK except chunks of Germanium... <g>) , what you can see with an imager are surface temperature differences and so might detect them with a seeker. What sort of detection level can these seekers do anyway ?

These cannot see through walls of any kind. The example used is from the manufacturer's website and it most likely refers to the ability to sense body heat down a hallway.

The heat seekers sense differences in temperature. The greater the difference, the more likely it is that the heat seeker will find it. A person wearing heavily insulated clothing may not be picked up, or a person wearing normal clothing on a 95 degree summer day. It will, hopefully, be able to sense a bonfire that has been lit in the middle of a frozen lake.

In the information section for AimSHOT HeatSeeker 3500 an example of usages is: Searching a building to find an armed felon. I'm tempted to chide you and ask you how it is able to determine whether or not a person is a felon or not, but I'll refrain. Seriously, though, I don't understand what is meant by the example. To what extent can the device detect heat on the other side of interior walls? Exterior walls?
