Thermal detection cameras are designed to capture heat energy. The sensors on thermal detection cameras allow the user to view the otherwise invisible infrared spectrum, which exists at wavelengths between visible light and microwaves. In no light or low light environments, thermal sensors display warm areas at higher contrast with sharper clarity.
Cameras with thermal detection work best in darkness. Light may be detected at a depth of 1,000m in the ocean, but there is rarely any significant light beyond 200 meters. Subsea and underwater cameras offer options and features with integrated LEDs and LED light rings to assist in the detection abilities of these high performance, low light / no light cameras.
