Many people use burglar alarm systems for keeping their homes secure. The presence of these devices warns the occupants when intruders break in to the house. In many high-security complexes, the use of night vision cameras is popular. These cameras enable the viewers to spot intruders in low visibility conditions. These cameras typically work by amplifying the amount of light present in the area. As such, the viewers will easily be able to spot people even in the night. But, night vision cameras are of no use when the visibility levels are extremely poor or when they drop to zero.
In this scenario, thermal imaging cameras have caught the imagination like never before. Regular cameras take pictures of the object based on the amount of light present in the area. In contrast, thermal imaging cameras do not need good visibility for providing images. Instead of providing images of the object as regular cameras do, they produce thermal images of the object based on the quantum of heat emitted by the object. Any object will emit infrared rays. Thermal imaging cameras detect and capture this. Thus, even if you use drone thermal cameras in zero visibility, smoky or foggy conditions, they will produce images that are quite helpful.
There are two kinds of thermal imaging cameras. Some cameras feature cooled infrared detectors, while others do not have cooled detectors. Thermal cameras with cooled infrared detectors are ideal for use in cold temperature areas. They will provide the desired infrared sensitivity in areas experiencing temperatures ranging from 4K to below room temperature. But, these cameras feature cooling systems. This makes them both bulky and expensive. In contrast, cameras with uncooled infrared detectors are ideal for use in ambient temperatures. This ensures that they don’t need any cooling equipment for functioning. Because of this, these cameras are more compact and relatively more affordable than their cooled counterparts. But, these cameras typically produce images having lower resolution and image quality than their cooled counterparts.
