This device has a much larger temperature sensor and display resolution compared to devices in the same price range. This device is very useful for homeowners, travelers or spies. It can be used to find intruders/animals in the dark. It can also be used to quickly find anything that might be overheating when a fire alarm goes off for no apparent reason. Another good use is for finding spy gadgets/hidden cameras while traveling. All operating electronics generate heat. You can also see which security cameras are fake and which are real if you need to know such things. It can also tell you if someone recently drove a car, walked barefoot in an area, opened a door, or what buttons they pressed.
