Every Camera Sensor has ability to see Infrared i.e. Thermal Part of The Light but Infrared Blocking Filter Inside Digital Cameras protects The CCD Sensor From burning with high energy Infrared light such as sunlight. Now, If We remove the blocking Infrared Filter the camera can also able to see Infrared Part of The Spectrum of Light that is the night vision camera. Which Is Pretty Cool Because After This Hack You Can See Hot Objects in Infrared camera With this Camera Glowing More As They Emit More Infrared Energy & Many Other Things You Can Do Like See Through Some Clothes , Black Objects Which Takes Tear down To a Next Level and use this as camera as infrared camera and night vision camera. aka camera infrarouge.
As a hobbyist ,considering i paid 5-10 $ for smartphone camera module and lens parts ,its something i can get my handson + it captures 4K and 240 fps slomo !
Please let me know your ideas to improve this camera , Thanks.

while it is *cool* it is not a thermal camera. technically any camera is a thermal camera, but we call thermal cameras those that see blackbody radiation in the LWIR or MWIR. a truly passive camera.
Your video is just clickbaiting at times. You seem to know enough to make a proper educational video about the topic but chose not to.

No need to be rude, you are always welcome to go and make a better video with a true cool camera.

As has been mentioned, it is possible for a normal CMOS-type camera to see the short wavelength radiation from very hot items that aren't hot enough to be incandescent and thus be visible to the naked eye. Here's a backyard example.
I had been burning some wood waste in my garden brazier earlier in the day, only leaving it after the flames had died down. Some hours later, well after dark, I was surprised to see it apparently glowing brightly on my security camera. It's just a cheap visible / near-IR auto-switch camera, nothing special, but it saw the heat from the brazier. Virtually nothing was visible to the naked eye; it wasn't even glowing dim-red. This implies it was cooler than the Draper Point (https://en.wikipedia.org/wiki/Draper_point) (~525°C, 977°F); as has been noted elsewhere, anything over about 400°C begins to emit a small amount of energy in the wavelengths that can be detected by silicon sensors (ie about 1.1µm or 1100nm).
