Can Infrared Sensors See Through Walls

Microwave is akin to radar.

Can infrared sensors see through walls.

In this way police can monitor human beings whose body temperatures are fairly consistent from a distance. Thermal imaging devices can t see through walls. Well annabee its got me puzzled. If you point a thermal camera at a wall it will detect heat from the wall not what s behind it.

Xandem s secret sauce is its use of radio waves. Moreover technicians use false color software to represent particular temperatures with a particular color. Walls are generally thick enough and insulated enough to block any infrared radiation from the other side. For most common materials used in buildings you cannot see through the walls.

The thermal image can also show missing insulation behind walls or above ceilings in the attic. No thermal cameras cannot see through walls at least not like in the movies. Heat sensing infrared systems don t have that weakness but they re prone to false alarms and can be blocked by anything that insulates body heat. A picture of a bedroom and its thermogram showing the framing members behind the drywall.

I think i can say with certainty that an infrared sensor cannot see through walls. You will only see emitted infrared radiation from the surface of the wall lwir swir regions or reflected infrared. The walabot is a new 3d imaging sensor that can detect movement and speed see through walls and analyze materials to tell you their composition. Infrared is similar in that it gives us an idea of the framing behind the wall in particular where framing members are relative to each other.

That s what the seek thermal camera does. Yes microvave can penetrate possibly a timber door but hardly a concrete wall and then pick up your movement on the other side.
