How Do Various Maritime Agencies Utilise Infrared Thermal Imaging Cameras in their Day-to-Day Operations?

Thermography (or thermal imaging) is the process by which human beings are able to view things in the infrared portion of the spectrum. As mentioned previously, each object has a unique heat signature. Thus, each object emits some amount of thermal radiation at any given point in time. However, this energy or infrared radiation is not visible to naked eye. Therefore, human beings need to use devices that can capture images in the infrared portion of the spectrum. Infrared thermal imaging cameras render this possible. Many people feel that thermal cameras are synonymous with their night vision counterparts. But, this is not the case. Unlike night-vision cameras, thermal cameras can reveal objects in the darkest of nights. This aspect makes it ideal for viewing objects even if these objects remain obscured because of rain, snow, fog or smoke.

People in the military often use infrared thermal imaging cameras. These cameras usually come into deployment in the border areas. However, many maritime agencies use these devices as well. These devices are ideal for various purposes such as:

Maintaining Surveillance and Security Levels: Thermal cameras provide exceptional night vision. Thus, the security personnel in various maritime agencies use these devices for keeping a watch on the presence of intruders. In some cases, these agencies use these cameras for keeping an eye on the anchored boats and ships as well.
Conducting Search and Rescue Missions: Locating people who have fallen overboard can be difficult in some cases. In this scenario, using thermal IP cameras can be useful. These cameras produce images based on heat, not light. Thus, they can easily pick up variations in temperature levels. This makes it easier for the rescue personnel to rescue the unfortunate individuals easily.
Navigating the Waters on Night-Time Missions: On occasions, some maritime agencies (such as the coast guard), need to conduct surveillance missions at night. It is worth highlighting that not all parts of the coast will have sufficient levels of illumination. In this scenario, having thermal imaging devices could make it easier to identify the presence of unlawful elements. In addition, these devices could make it easier to navigate the waters by highlighting the presence of other vessels, structures, debris etc.
