Depending on how much you're willing to spend on the cameras, they can be pretty beneficial. If you do install thermal imaging cameras, they will be able to pick up heat from bodies. It doesn't matter how dark it is also. Since the cameras work off of heat, there is not getting by these!
Thermal Imaging cameras work on a 14,000nm wavelength, which is perfect for working in poorly lit (dark) places due to their ability to capture heat emitted by objects (hence not requiring light for the camera to detect objects). Basic thermal imaging cameras cost $1,000-$2,000. Specialized thermal imaging cameras (such as those used by fire departments) cost around $9,000 each.
There are a number of different FLIR camera that have thermal imaging. In fact, all of FLIR's cameras have thermal imaging, and are used by military, police, and civilians.
FLIR is the global leader in thermal imaging infrared cameras.
Thermal imaging cameras are most commonly used by firefighters for finding the seat of structure fires, locating victims, spotting smoldering fires inside walls, and detecting electrical wiring that is overheating. They are also used for search and rescue operations in various low-visibility conditions. Thermal imaging cameras used by firefighters are highly durable. They are heat-resistant and contained in a rugged, waterproof housing.
Thermal imaging cameras are generally expensive. New ones typically cost at least $1000. However, you can get it lower if you buy a used one from Ebay or Amazon marketplace.
The emissivity of skin is important in thermal imaging because it affects how accurately the temperature of the skin is measured. Skin with higher emissivity will provide more accurate temperature readings in thermal imaging technology.
An infrared camera detects infrared radiation, while a thermal camera measures temperature differences. The main difference is in their intended use: infrared cameras are used for imaging, while thermal cameras are used for temperature measurement. This impacts their applications as infrared cameras are used for surveillance, medical imaging, and research, while thermal cameras are used for monitoring equipment, detecting heat leaks, and firefighting.
Fluke makes several different kinds of thermal cameras and thermal imaging devices. You can try www.fluke.com and just browse through them or follow this link to go directly to them www.fluke.com/fluke/usen/thermal-imaging/ti25.htm?PID=56723.
You can measure an object's temperature using a thermometer. Make sure the thermometer is in direct contact with the object to get an accurate reading. Other methods include using infrared thermometers or thermal imaging cameras.
FLIR systems sells some really well made thermal imaging cameras. Their prices aren't considered "cheap" but neither are their products. They last and work exceptionally well.
Thermal infrared cameras are used for many things. Examples of this are with firefighters. Firefighters use these cameras to see through smoke and possibly through walls. Also, police officers may use these cameras to seek out running criminals in the dark. People interested in the supernatural may additionally use thermal infrared cameras as it can help to see paranormal apparitions.
