The use of drones has become increasingly popular in various industries, including construction, agriculture, and filmmaking. One of the key features that make drones so versatile is their ability to capture high-quality images and videos from unique perspectives. But can drones see beyond the visible spectrum? In this article, we’ll explore the world of infrared cameras and their integration into drones.
What are Infrared Cameras?
Infrared cameras are specialized devices that capture images using infrared radiation, which is invisible to the human eye. These cameras are designed to detect temperature differences in objects, allowing them to produce images that reveal details not visible in the visible spectrum. Infrared cameras have a wide range of applications, including:
- Predictive maintenance: Infrared cameras can detect temperature anomalies in equipment, allowing for early detection of potential issues.
- Energy auditing: Infrared cameras can help identify areas of heat loss in buildings, making it easier to optimize energy efficiency.
- Search and rescue: Infrared cameras can detect the heat signatures of people, making it easier to locate missing persons.
How Do Infrared Cameras Work?
Infrared cameras work by detecting the infrared radiation emitted by objects. All objects emit some level of infrared radiation, which is a function of their temperature. Infrared cameras use a specialized sensor to detect this radiation and produce an image. The sensor is typically made of a material that is sensitive to infrared radiation, such as mercury cadmium telluride (MCT) or indium antimonide (InSb).
The sensor is usually cooled to a very low temperature using a cryogenic cooling system. This cooling system helps to reduce the noise in the sensor, allowing for more accurate temperature measurements. The sensor is then connected to a processing unit that converts the infrared radiation into a visible image.
Do Drones Have Infrared Cameras?
Yes, some drones are equipped with infrared cameras. These drones are often used for specialized applications such as:
- Thermal inspection: Drones equipped with infrared cameras can be used to inspect buildings, bridges, and other infrastructure for signs of heat loss or damage.
- Agricultural monitoring: Infrared cameras can be used to monitor crop health, detect moisture levels, and identify areas of stress.
- Search and rescue: Drones equipped with infrared cameras can be used to locate missing persons in a variety of environments.
Types of Infrared Cameras Used in Drones
There are several types of infrared cameras that can be used in drones, including:
- Uncooled infrared cameras: These cameras use a sensor that is not cooled, making them more affordable and compact. However, they are less sensitive than cooled infrared cameras.
- Cooled infrared cameras: These cameras use a sensor that is cooled to a very low temperature, making them more sensitive and accurate. However, they are more expensive and require more power.
- Short-wave infrared (SWIR) cameras: These cameras detect infrared radiation in the short-wave spectrum, which is less affected by atmospheric interference. They are often used for applications such as mineral exploration and environmental monitoring.

What is an infrared camera and how does it work?
An infrared camera is a type of thermal imaging camera that captures images using infrared radiation, which is invisible to the human eye. It works by detecting the temperature differences in a scene and converting them into visible images. This allows the camera to “see” objects and environments in complete darkness or through smoke, fog, and other obscurants.
Infrared cameras are commonly used in various applications, including surveillance, search and rescue, predictive maintenance, and environmental monitoring. They can detect heat signatures, track temperature changes, and provide valuable insights into the thermal properties of objects and environments. By using infrared cameras, drones can gather critical information that would be impossible to obtain with traditional visible-light cameras.
Do all drones come equipped with infrared cameras?
No, not all drones come equipped with infrared cameras. While some high-end drones, especially those designed for industrial or commercial applications, may have infrared cameras, many recreational drones do not. Infrared cameras are typically more expensive than traditional visible-light cameras, and they require specialized sensors and software to process the thermal data.
However, some drone manufacturers offer infrared camera upgrades or accessories that can be installed on certain drone models. Additionally, some third-party companies specialize in designing and manufacturing infrared camera systems for drones. These systems can be integrated into existing drones, providing users with the ability to capture thermal images and videos.
What are the benefits of using drones with infrared cameras?
The benefits of using drones with infrared cameras are numerous. One of the primary advantages is the ability to capture thermal images and videos in complete darkness or through obscurants.
