Infrared Detector Market Opportunity

THE INTEGRATION OF INFRARED DETECTORS IN THE INTERNET OF THINGS(IOT) AND SMART DEVICES

The integration of infrared (IR) detectors on the Internet of Things (IoT) and smart devices presents a significant opportunity for the growth of the infrared detector market. As IoT and smart technologies continue to gain momentum across various sectors, the demand for advanced, energy-efficient sensors, including IR detectors, is rapidly increasing. IR detectors can enhance the functionality of IoT devices by enabling non-contact temperature measurement, motion detection, and environmental monitoring, contributing to smarter and more responsive systems. 

A real-time example of this opportunity is the use of IR sensors in smart home devices. Companies like Nest (owned by Google) integrate IR-based motion sensors in smart thermostats and security cameras. For example, the Nest Thermostat uses an IR sensor to detect the presence of people in a room, adjusting the heating or cooling based on occupancy, thus optimizing energy consumption. Similarly, IR sensors in smart security cameras, such as those offered by Arlo, enable motion detection and night vision, allowing homeowners to monitor their property efficiently in both daylight and darkness.

In industrial applications, IR detectors are being integrated into IoT systems for predictive maintenance. For instance, infrared sensors embedded in industrial machines can detect temperature variations, signaling potential equipment failures before they occur. This capability is being adopted in industries like manufacturing, where companies such as GE and Siemens are using IR sensors as part of their IoT-enabled predictive maintenance systems to reduce downtime and prevent costly breakdowns.

Furthermore, in the healthcare sector, the integration of infrared detectors into wearable devices is offering new opportunities for continuous health monitoring. For example, devices like fitness trackers and smartwatches are incorporating IR sensors to monitor body temperature, helping users detect early signs of illness or fever without the need for physical contact. In summary, the integration of infrared detectors into IoT and smart devices is a growing opportunity within the market, with real-time examples across smart homes, industrial maintenance, and healthcare. These technologies not only improve the functionality and efficiency of devices but also offer users enhanced convenience, safety, and energy savings.

Infrared Detector Market Segment Insights

Infrared Detector by Type Insights

Based on Type, this segment includes Thermal Infrared Detectors and Photonic Infrared Detectors. The Thermal Infrared Detectors segment dominated the global market in 2024, while the Photonic Infrared Detectors segment is projected to be the fastest–growing segment during the forecast period. Thermal infrared detectors are devices that measure temperature changes caused by infrared radiation. thermal detectors are to take advantage of the thermal effect to heat the detection element and cause heat transformation of some physical properties so that the IR radiation energy can be detected. 

Thermal detectors are frequently used in spectral regions which are difficult to access with photon detectors – in particular, for long-wavelength infrared light. Also, they are used where their low speed, moderate sensitivity and low dynamic range is no serious problem – for example, as optical power meters for lasers. The thermal detector works at room temperature. During its operation, there are temperature changes, which may have slow response, and a relatively low sensitivity compared with photon detectors.

Infrared Detector by Wavelength Insights

Based on Wavelength, this segment includes Near-Infrared (NIR), Mid-Wavelength Infrared (MWIR), Long-Wavelength Infrared (LWIR). The Long-Wavelength Infrared (LWIR) segment dominated the global market in 2024, while the Mid-Wavelength Infrared (MWIR) segment is projected to be the fastest–growing segment during the forecast period. Long-wave infrared and technology get used in actual military operations. These cameras detect thermal emissions from people, animals, and vehicles when they emit heat at higher temperatures than the surrounding atmosphere.

LWIR are less sensitive to thermal “noise” in the environment and thus are useful outdoors. They can “see” through foliage to detect heat emissions from enemy fighters, dangerous predators, or hidden vehicles. They can also detect roadway hazards in very dark conditions helping to avoid collisions with animals or vehicle damage by unexpected potholes or washed-out areas. Long-wave infrared or LWIR is a subset of the infrared band of the electromagnetic spectrum, covering the wavelengths ranging from 8µm to 14µm (8,000 to 14,000nm). This is the radiant heat that uncooled thermal imaging cameras see. Uncooled LWIR thermal imaging can be more affordable than cooled MWIR thermal imaging, as the sensors require fewer complex components and less ongoing maintenance.

Infrared Detector by Materials Insights

Based on Materials, this segment includes Indium Arsenide (InAs), Indium antimonide (InSb), Indium Gallium Arsenide (InGaAs), Mercury-Cadmium-Tellurium (MCT), Vanadium oxide (VOx), Amorphous silicon (α-Si), Others. The Vanadium oxide (VOx) segment dominated the global market in 2024, while the others segment is projected to be the fastest–growing segment during the forecast period. 

Vanadium Oxide (VOx) is a material used in uncooled infrared detectors, known for its temperature-dependent resistance. It is widely used in microbolometers for thermal imaging and IR sensing. VOx-based detectors offer high sensitivity and cost-effectiveness. They play a key role in applications like automotive, healthcare, and security.

Infrared Detector by Application Insights

Based on Application, this segment includes Security and Surveillance, Gas Detection, Temperature Measurement, Others. The Security and Surveillance segment dominated the global market in 2024, while the Gas Detection segment is projected to be the fastest–growing segment during the forecast period. Infrared detectors play a crucial role in security and surveillance applications, offering advanced monitoring capabilities that are not reliant on visible light. These detectors can detect infrared radiation, which is emitted by objects based on their temperature, allowing them to "see" in complete darkness.

In security systems, infrared detectors are commonly used in motion sensors, night-vision cameras, and perimeter surveillance systems to monitor areas even under low-light conditions or at night. They can detect human presence, vehicle movement, or unauthorized activities, providing real-time alerts to security personnel. The ability to detect heat signatures ensures enhanced surveillance, making it harder for intruders to evade detection. Additionally, infrared detectors are often integrated with thermal cameras, improving the effectiveness of security systems in diverse environmental conditions, including fog, smoke, and darkness.

Infrared Detector by End-User Industry Insights

Based on the End-User Industry, this segment includes Defense and Aerospace, Automotive, Healthcare, Industrial Manufacturing, Others. The Defense and Aerospace segment dominated the global market in 2024, while the Automotive segment is projected to be the fastest–growing segment during the forecast period. Infrared detectors play a critical role in the defense and aerospace industries, where they are used for a variety of advanced applications such as surveillance, targeting, navigation, and threat detection.

In defense, infrared sensors are integral to night-vision systems, allowing military personnel to observe and track targets in low-light or complete darkness by detecting the infrared radiation emitted by warm objects. They are also used in missile guidance systems, where they help accurately track and lock onto targets based on their heat signatures. In aerospace, infrared detectors are used in various applications, including aircraft and spacecraft thermal imaging, detecting engines or structural malfunctions, and monitoring environmental conditions.
