What materials can block infrared cameras and camera peeping

Infrared perspective photography mainly uses the principle of infrared thermal imaging, which only needs heat insulation. Thicker breathable clothing can shield it.

Another type of infrared detection equipment is manufactured using the principle of emitting infrared rays, reflecting them and then receiving them to detect objects. This can only be shielded with metal.

Current infrared cameras and cameras use the first method. Because the instrument in the second method is too large to be carried.
