Thermal vision systems sense and image the IR emissions from objects that make vision possible in total darkness, through smoke, fog, and other bad weather with no illumination at all. Thermal sensors cover a range of products including portable surveillance and weapon sights, static and mobile cameras, thermal scopes, and small OEM boards. The technology is split into cooled devices offering greater sensitivity for military targeting purposes at greater ranges, and uncooled microbolometers for the civilian and industry as well as basic defense market segments. Thermal radiation is categorized by wavelength bands such as SWIR, MWIR, and LWIR.
The strategic value of thermal imaging has grown because three different operational needs for counter-UAS systems border security operations and industrial predictive maintenance programs have created separate requirements for new system acquisition. Military and police agencies now require thermal imaging as an essential standard instead of treating it as an optional upgrade. European Union industrial facilities are increasing their use of thermal cameras because they need to meet regulatory energy efficiency requirements for their electrical and mechanical inspection programs. The automotive original equipment manufacturer market now establishes a continuous flow of thermal pedestrian detection systems which will increase throughout the projection period.
In 2024, Teledyne FLIR expanded its Boson uncooled thermal module platform targeting defence, automotive, and industrial OEM customers requiring compact, integration-ready thermal sensor solutions at commercial production scale.
Recent Developments
In February 2024, The Teledyne FLIR company has unveiled an increase in the manufacture of the Boson and Neutrino thermal module platforms, which are meant to serve the OEM customers in the defense, automotive, and industrial markets. This increase is informed by the continued need for ready-to-integrate thermal sensor modules among systems manufacturers who do not require the whole camera to be assembled.
In May 2024, Safran Group announced contract awards for cooled thermal imaging systems targeting European military vehicle and aviation platform upgrade programmes. The contracts demonstrate NATO member countries' increasing military budgets because they require high-sensitivity cooled detectors for fire control operations and long-range target acquisition tasks which uncooled technology fails to deliver as operational performance standards demand for vehicle-mounted and airborne fire control systems.
In September 2024, Leonardo DRS announced advanced thermal weapon sight deliveries under US Army infantry modernisation contracts targeting soldier systems integration programmes. The US Army thermal imaging program which provides standard thermal equipment for infantry soldiers has delivered multiple thermal weapon sights to Leonardo DRS which the company will use to produce the equipment over multiple years of the program.
In January 2025, The Axis Communications has recently launched a new range of thermal cameras that are dedicated to protecting the infrastructure and the perimeters of industrial sites. This launch is in response to the rising number of requests from utility companies, oil and gas facilities, and security teams at industrial campuses for thermal cameras in areas where visual surveillance cameras cannot operate.
Market Dynamics
Defence modernisation and counter-UAS demand are driving sustained global thermal imaging procurement growth.
What drives the commercial growth potential of thermal imaging products is the overlap between investment into defence modernization and counter-Unmanned Aerial System (UAS) capabilities on behalf of military and security actors worldwide. Rising NATO military expenditure after 2022 and increasing military investments in the Indo-Pacific region create a need for thermal purchases in the segments of vehicles, infantry, aircrafts, and stationary observation devices alike. Counter-UAS operations also lead to additional budgets dedicated specifically to the procurement of thermal imaging equipment capable of detecting drones at night and beyond visual range.
High cooled detector costs and ITAR export constraints limit programme accessibility and market expansion pace.
The military targeting systems that operate at long distances require cooled thermal systems which have high unit costs as their main limitation and face export control restrictions under ITAR which delays technology transfer to partner countries. The existing prices of cooled systems exceed the budget limits of law enforcement agencies and commercial businesses which need cost-effective solutions. ITAR compliance overhead adds programme timeline complexity for US suppliers serving international defence procurement, creating competitive space for European alternatives in allied nation contracts where technology transfer restrictions create commercial friction.
Industrial predictive maintenance and automotive thermal integration create high-volume new commercial demand.
The implementation of industrial predictive maintenance creates a continuous growth path for thermal imaging solutions because manufacturing plants begin using thermal cameras to inspect electrical panels and monitor bearings and identify process anomalies. The establishment of every new EU industrial energy efficiency compliance requirement results in additional thermal inspection procurement needs for facilities that must conduct ongoing thermal auditing. The thermal pedestrian detection system developed by automotive OEMs creates a new high-volume embedded sensor procurement channel which will grow substantially throughout the forecast period because of expanding EV and autonomous vehicle programs.
Commoditised uncooled sensors from Asian manufacturers intensify pricing pressure on established Western suppliers.
The threat faced by the existing thermal imaging providers is the emergence of the uncooled detector manufacturing industry in China, which is producing thermal cameras that are competitive in terms of cost compared to the products offered by the existing companies. The government’s preference to purchase domestically-made thermal devices for the US and European markets provides some relief, but the margins of both the commercial and export markets will continue to erode due to the emergence of Chinese thermal devices with capabilities approaching those of the Western devices.
AI-integrated thermal analytics and multi-sensor fusion are reshaping thermal imaging system value propositions commercially.
The commercially most relevant technology development is the addition of AI-driven analysis capabilities to thermal imaging equipment, allowing for automated detection and identification of anomalies, which turns thermal cameras from merely passive observation devices into proactive decision support tools. Multi-sensor fusion involving thermal and visual detection, as well as radars or acoustic detectors, is providing capabilities that cannot be provided by a single sensor alone. Such capabilities allow for continued high prices in the security and critical infrastructure markets while also generating service revenues.

Dominating Segments
Uncooled thermal technology leads by volume through cost efficiency and broad commercial application accessibility.
Uncooled detectors have been segmented more dominantly than cooled ones due to volume units and also they are experiencing greater growth rates compared to their cooled counterparts in business, law enforcement, and basic defense applications. The manufacturing cost of microbolometers has been decreasing steadily throughout the last ten years; therefore, it is now affordable in industries such as industrial inspection, border control, firefighting, and vehicle integration in which cooled sensors were too expensive for use before. Lack of requirement for cooling sensors has resulted in removing the maintenance requirement and hence making it available on platforms other than military ones for which cooled sensors require expertise for operation.
In February 2024, Teledyne FLIR expanded its Boson uncooled module platform targeting automotive and industrial OEM customers, reinforcing uncooled technology's dominance in volume commercial thermal imaging procurement.
Aerospace and defence vertical leads thermal imaging revenue through defence programme scale and system value.
