@6:48 "Of course we've got color palettes like everyone else *visible disinterest*" lmao. Interesting to learn about the cutoff filters in this setup.

Can you show us FLIR cams? I was told and have a hard time believing they can see people shapes from us walking around inside our brick houses. What can FLIR see?

Look at the windows in video… they even block the thermals … you have a better chance to look through windows with your bare eyes. Unless there is a really hot source or cold you wont see anything in buildings with retail thermals.

@@mace41canuck That was my thought but two cops (one a detective) and a tank turret mechanic told me otherwise and got belligerent when I didn't take them at their word.

@@mace41canuck BTW this was my first time seeing this channel and I didn't know when I subscribed it was basically a sales promo channel.

@@TobyCatVA i just ask AI and this is the response. Thermal cameras can detect heat signatures, which means they can indeed see people and warm objects through certain materials, but this doesn't extend to seeing through all types of walls and windows: - **Windows:** Typically, thermal cameras can see through regular glass windows quite effectively because glass is transparent to infrared radiation. However, if the window is coated with certain materials or films designed to block infrared, the camera's effectiveness might be reduced. - **Walls:** - **Thin or Lightweight Materials:** They might detect heat signatures through very thin walls or materials like plywood or some types of siding, especially if there's a significant temperature difference. - **Thick or Dense Materials:** For standard building materials like brick, concrete, or thick wood, thermal cameras will not see through them. These materials block or absorb infrared radiation, preventing it from passing through. - **Gaps and Insulation:** Thermal cameras can sometimes detect anomalies where heat might escape, like around windows, doors, or through poor insulation, but this isn't "seeing through" the wall so much as detecting heat loss patterns. - **Limitations:** - The thickness, density, and composition of the material significantly affect penetration. - The temperature difference between the object/person and the background is crucial. A greater difference makes detection more likely. - Interference from other heat sources outside the wall can confound readings. In summary, while thermal cameras are excellent for detecting heat differences and can sometimes give you information about what's on the other side of certain barriers, they are not capable of seeing detailed images or clear outlines of objects or people through solid, dense walls like those in most homes or buildings. They're more about detecting heat patterns and anomalies rather than providing X-ray vision.
