Currently, civilian thermal imagers cannot penetrate walls to monitor others, so you can rest easy. Only military thermal imagers can achieve this, and they are not available for sale. While civilian thermal imagers cannot penetrate walls, there are some that can achieve low-light penetration, such as the Guide GL-25B.
Thermal imaging and low-light-level imaging are two typical night vision technologies, primarily used to observe surrounding conditions in dark environments with minimal or no visible light. Infrared imaging uses infrared light, invisible to the naked eye, radiated or reflected by objects to form an image on a photosensitive element, which is then displayed electronically. Since no object can reach absolute zero (-273 degrees Celsius), all objects have infrared radiation properties. However, infrared radiation, like visible light, has a longer wavelength and a spectrum outside the red wavelength. Therefore, visible light cannot penetrate opaque walls, and neither can infrared radiation. Only high-energy particles (in the far ultraviolet) can penetrate walls. The shorter the wavelength, the greater the penetration. For example, X-rays can penetrate the human body, alpha particles can pass through steel plates of a certain thickness, and neutron beams can even penetrate heavy metal!

Application Areas
Suitable for low-altitude economic operations, emergency rescue, counter-terrorism, reconnaissance, border defense, drug control, night vision, border patrol, border inspection station monitoring, water search and rescue, prison monitoring, night vision patrols, and epidemic prevention.
This shows that your concerns are unnecessary. Infrared cannot see through walls, and the image is infrared-specific. The hotter the area, the brighter the image, completely different from what you normally see!
