Long range LWIR and MWIR cooled and uncooled FLIR Airborne reconnaissance is a critical part of military strategy. Long range Thermal infrared cameras offer a detailed overview of the battlefield, even in complete darkness. SPI has developed the only true high-definition (HD) thermal infrared camera, with advanced features that make it ideal for aerial surveillance.

Airborne reconnaissance has been an essential part of military intelligence gathering since the First World War when aircrafts fitted with cameras took aerial photographs of enemy lines and activities. Since then, aerial surveillance has progressed rapidly in line with technological developments to include some of the most advanced cameras and sensors currently available.

Airborne Reconnaissance Fuels Military Tactics

Today airborne reconnaissance is critical for gathering battlefield intelligence and monitoring the movements of troops, vehicles, and weapons. Typically, aerial surveillance is conducted by unmanned aerial vehicles (UAV), and miniature UAVs (drones). More than 7000 drones with surveillance capabilities were deployed in Iraq and Afghanistan during wars in the early 21st century.

Recent technological developments have reduced the price of drones and increased their availability. As a result, aerial photography and surveillance have now found a plethora of non-military applications including environmental analysis, law enforcement, security, wildlife monitoring, wildfire surveillance, archaeology, urban studies, search and rescue.

Wide Area, HD Surveillance Provides a Detailed Overview of Entire Zones

Most aerial surveillance relies on video streaming to transmit images back to tactical command centers. However, optical video surveillance comes with several drawbacks. While videos can provide detailed images, their small field of view doesn’t provide a large tactical overview.

To achieve wide area surveillance and visualize the bigger picture, reconnaissance aircrafts use pods that combine many sensors to provide a series of images that are ‘stitched together’ to cover an area up to 39 square miles with high enough resolution to track individual people.

Thermal Imaging Cameras Can Visualize in Darkness

To have the upper hand in modern warfare, the military requires technology that can provide unblinking intelligence data from an entire conflict zone, day and night, in all weather conditions. Although optical cameras can now provide wide area surveillance, their images can be easily disturbed by darkness, smoke, fog, rain, and snow. The latest airborne reconnaissance aircrafts now combine optical video surveillance and passive thermal infrared camera arrays to provide a constant overview of the battlefield that is unaffected by weather and darkness.

Passive thermal imaging cameras, also known as Forward-looking infrared (FLIR) cameras, detect infrared radiation directly from objects such as people or vehicles, so no external illumination is required. The images produced correspond to thermal gradients in a scene, revealing people and objects from miles away, even in complete darkness and challenging conditions. What’s more, thermal infrared cameras can visualize objects and situations that may not be visible to the human eye, including gases and obscured objects.

Traditional surveillance and monitoring solutions often provide limited coverage, especially at night and in poor weather conditions. Mid-Wave Infrared (MWIR) cameras use thermal imaging or FLIR technology to provide an advanced solution for long-range imaging in all weather and light conditions.

Recent technological advances mean that MWIR mid wave infrared cameras are now widely accessible for applications from perimeter surveillance to laboratory research. SPI Corp supplies a wide range of MWIR cameras and components which offers compact size, best in class pricing and unrivaled performance. Our moray grade IR cameras will suit your needs. They are ideal for integrating into your new custom project or used as is.

Crime, terrorism, cross-border dangers, and increased awareness of potential threats mean that security, monitoring, and surveillance are more important today than ever before. Traditionally, closed-circuit television (CCTV) cameras have been used for perimeter surveillance and security imaging. However, CCTV cameras rely on detecting visible light, so their applications are limited in the hours of darkness. What’s more, perimeters and borders are often extensive areas and CCTV cameras can typically only cover areas up to 30 meter which means maintaining cameras and lights for large areas can be complicated and expensive.

Mid-Wave infrared (MWIR) thermal imaging cameras, which can operate in complete darkness and can cover many miles, and offer an advanced alternative to CCTV for round-the-clock surveillance. Furthermore, thermal imaging cameras can visualize objects and situations that may not be visible to the human eye, such as gas leaks and covered or obscured objects. Our long range thermal infrared cameras are available in gimbals, PTZ (Pan Tilt Zoom), and standalone platforms. These systems offer SWaP, military grade performance, low cost, low maintenance, reliability and ruggedness for 24/7/365 uninterrupted ISR.

Thermal Infrared FLIR Cameras Can be Used in Land, Sea and Air for manned or unmanned applications

Thermal imaging FLIR cameras have been widely used in military applications for some time, but until recently high costs have prohibited their further application. However, recent technological advances have resulted in thermal imaging systems that are less expensive, more compact, and more reliable than their predecessors.

Thermal imaging FLIR camera systems are now utilized in land, marine and airborne monitoring in applications including perimeter patrol, search and rescue, police searches, wildlife research, fault detection, leak detection, mine detection, and firefighting.

MWIR (Midwave) for Continuous Monitoring, Radiometry and Research

MWIR IR cameras excel at long-range surveillance applications including airport perimeter security, vessel traffic monitoring, and critical infrastructure protection. To be detected by passive infrared cameras, infrared radiation must travel through the atmosphere to the detector. The range of LWIR cameras is often limited by absorption, scattering, and refraction of LWIR radiation by water vapor and CO2 in the atmosphere. As MWIR radiation travels through the atmosphere, it is less affected by absorption and scattering than LWIR.

As a result, MWIR Thermal cameras provide the longest detection ranges, seeing about 2.5 times further than LWIR, enabling them to detect humans, vehicles, and objects many miles away.

MWIR FLIR cameras can operate in all weather conditions and environments, including high humidity. LWIR cameras are more affected by humidity than MWIR cameras, making MWIR particularly suited to marine and coastal environments. Furthermore, MWIR cameras are also typically smaller and lighter than LWIR cameras with similar optics, making them the obvious choice in applications with space or weight limitations, such as airborne operations.

MWIR thermal imaging cameras provide superior sensitivity and contrast with low sensor noise, resulting in high-quality images. Clearer images are possible with MWIR as thermal contrast if often greater in the MWIR band than the LWIR band. Furthermore, the noise equivalent delta temperature for an MWIR camera with long-range optics is typically better than an LWIR, resulting in sharper images.

For tracking fast moving targets or targets with a wide temperature ranges, MWIR delivers wide dynamic range with short integration times to track and visualize the target more clearly than LWIR. MWIR cameras provide superior sensitivity and flexibility, making them ideal for use both in the field and in the laboratory.


Slant Range is one of the most important operational considerations for selection of an airborne infrared thermal FLIR camera system.

The slant range is the straight line distance from camera to target. In long range airborne imaging applications, slant range often greatly exceeds the ground range or altitude (AGL) because of the look angle of the optics necessary to stay on the target. To maintain persistent surveillance of a stationary target or to effectively search for targets, it is necessary to vary the look angle of the optics and thus the slant range can change significantly during a flight. A common misconception is to consider only altitude (above ground level – AGL) or ground range in camera selection.


SWIR (Short Wave InfrarRed) technology has long been used for a vast multitude of applications because of its distinct features.

Some Industrial applications (solar cell inspection, bottling plant inspection, fruit inspection, fire fighting, etc.) and military applications (laser guiding systems, camouflage detection, surveillance, night vision, boarder monitoring, etc.).

The principle advantages of using SWIR technology in military applications is that SWIR IR imaging cameras generally “see through” and image higher contrast images compared to visible through haze, mist, rain, fog and challenging atmospheric conditions. Visibility can be achieved in long rage distances as far as 36 Kilometers.

For instance, A simple way of thinking about this is imaging a sunset. As the sun lowers towards the horizon, less and less blue, green and yellow light permeate the atmosphere as they have shorter-than-red wavelengths. Red light, with a longer wavelength is not scattered so easily (and infrared light even less so), so the sun appears red. Therefore, as the concentration of particles of water vapour in the atmosphere increases, shorter wavelengths are scattered more than longer wavelengths are. This makes imaging in visible, UV and X-ray very difficult or impossible through bad weather.

SWIR can also be used for night vision ISR applications, with and without specialty waveband lasers between 1060 nm and 1550 nm. These high power lasers also have the advantage that they are eye-safe at very long distances.

Good surveillance operations rely on robust equipment that can handle any environmental conditions. This is why government and private services worldwide are turning to SWIR technology for naval, air and ground security.

SWIR for Counter-Aerial Surveillance

Modern fighter jets are equipped with the latest stealth technology making their presence virtually undetectable with even cutting edge RADAR surveillance systems. When they are at their fastest before attack, as they are travelling well beyond the speed of sound, the noise of a fighter’s engine will arrive only after the attack is completed.

It is for these reasons that optical technologies are being incorporated into more and more anti-air systems. As an aircraft accelerates, the air temperature of the exhaust can exceed the minimum “visible” temperature with SWIR imaging.

How Do FLIR Thermal Infrared Imaging Work?

Passive thermal imaging cameras, also known as Forward-looking infrared (FLIR) cameras, detect infrared radiation directly from objects such as people or vehicles, with no external illumination required.

The electronic images produced correspond to thermal gradients in the observed scene. The infrared light detected by passive thermal FLIR imaging cameras falls into two ranges: Long-Wave Infrared (LWIR, 8µm to 12µm) and MWIR (3µm to 5µm). LWIR and MWIR cameras each have their advantages and disadvantages and which camera you should choose depends on the demands of your specific application.

Compact, Uncooled LWIR FLIR Cameras for Airborne Reconnaissance

There are two types of thermal imaging FLIR cameras: Long-Wave Infrared (LWIR), which detect light in the range 8µm to 14µm, and Mid-Wave Infrared (MWIR), which detect light in the range 3µm to 5µm. While MWIR cameras offer several advantages such as increased range and less disturbance by atmospheric conditions, they usually require cooling systems that can be heavy, bulky, and expensive.

Uncooled LWIR cameras are smaller, lighter, and significantly cheaper than cooled MWIR or LWIR cameras, making them ideal for use in airborne reconnaissance using drones.
