The use of the thermal camera in countering IEDs

In the modern operational context, the threat posed by improvised explosive devices (IEDs) continues to be one of the most insidious challenges for the armed forces, civil protection units, and security operators. In this scenario, the use of the thermal camera has established itself as a strategic tool for preventive detection, tactical verification, and support in neutralization of IEDs.

What is a thermal camera and how does it work

The thermal camera is an optical device that detects the infrared radiation emitted by objects, transforming it into thermal images. Every body emits heat differently, and these variations can be visualized to identify thermal anomalies indicative of tampering, burials, or suspicious presences.

Operational applications in countering IEDs

The use of thermography in countering IEDs is structured in several operational phases:

• Detection of concealed devices: IEDs buried or hidden under natural or artificial surfaces alter the thermal distribution of the ground. The thermal camera allows these anomalies to be detected, especially under conditions of differential solar heating.
• Inspection of vehicles and infrastructure: thermal analysis of engines, internal compartments, and structural surfaces can reveal hidden compartments or active devices.
• Support for robots and drones: thermal cameras mounted on UGV/UAVs allow remote inspections in high-risk environments, reducing direct exposure of operators.
• Verification of suspicious packages and containers: an active IED can generate residual heat from batteries, timers, or circuits. Thermography allows for an initial non-invasive assessment.

Advantages and limitations

Advantages:

• Remote and real-time operation
• Compatibility with other sensors (GPR, metal detectors, spectrometers)
• Usable in nighttime or low-visibility scenarios

Limitations:

• Sensitivity to environmental conditions (wind, rain, homogeneous surfaces)
• Need for qualified personnel to interpret images
• Does not replace other C-IED tools, but integrates with them

Integration into NATO protocols

Thermography is an integral part of NATO C-IED protocols, particularly in the pillars:

• Defeat the Device: detection and neutralization
• Prepare the Force: training and education
• Attack the Network: forensic analysis and technical intelligence

Conclusions

The use of the thermal camera in countering IEDs represents a technological and methodological evolution that strengthens the prevention and response capabilities of operational units. In a context where speed, safety, and precision are fundamental, thermography proves to be an indispensable tool for the protection of forces and the population.
