In recent years, infrared cameras have become a hot topic in the tech world, with many industries, including smartphone manufacturers, incorporating this technology into their products. Infrared cameras, also known as thermal cameras, use infrared radiation to capture images, providing a unique perspective that traditional cameras cannot replicate. From detecting heat signatures to monitoring temperature changes, infrared cameras have opened up new possibilities for various applications.
Why Do Phones Need Infrared Cameras?
Before we dive into the list of phones with infrared cameras, let’s explore the benefits of having this feature in a smartphone. Infrared cameras can enhance a phone’s capabilities in various ways:
- Thermal imaging: With infrared cameras, you can capture heat signatures, which can be useful for detecting temperature changes, monitoring energy efficiency, and even identifying heat-related issues in electronic devices.
- Night vision: Infrared cameras can produce clear images in low-light conditions, making them ideal for outdoor activities like camping, hunting, or surveillance.
- Health monitoring: Infrared cameras can measure skin temperature, allowing for accurate health monitoring, such as detecting fever or inflammation.
- Industrial inspection: Infrared cameras can help identify issues in industrial settings, such as overheating equipment or electrical faults.

How Do Infrared Cameras in Phones Work?
Infrared cameras in phones work by detecting the infrared radiation emitted by objects. This radiation is then converted into an image, which can be displayed on the phone’s screen.
Infrared Camera Types
There are several types of infrared cameras used in phones, including:
1. Uncooled Thermal Cameras
Uncooled thermal cameras use thermopiles or thermocouples to detect temperature changes. They are commonly used in smartphones due to their low power consumption and small size.
2. Cooled Thermal Cameras
Cooled thermal cameras use a cryogenic cooler to detect temperature changes. They are more accurate than uncooled cameras but require more power and are typically larger in size.
3. Quantum Dot Cameras
Quantum dot cameras use tiny crystals to detect infrared radiation. They offer higher sensitivity and faster response times than traditional thermal cameras.
Challenges and Limitations
While infrared cameras in phones offer many benefits, there are also some challenges and limitations to consider:
1. Cost
Infrared cameras are still relatively expensive to manufacture, which can drive up the overall cost of the phone.
2. Accuracy
Infrared cameras can be affected by environmental factors, such as temperature and humidity, which can impact their accuracy.
3. Resolution
Infrared cameras often have lower resolutions than traditional cameras, which can result in lower image quality.
Conclusion
Infrared cameras in phones are a rapidly evolving technology, offering new possibilities for various applications. From thermal imaging to night vision, these cameras can enhance the capabilities of a smartphone. While there are still challenges and limitations to consider, the phones listed above demonstrate the potential of infrared cameras in the mobile industry. As the technology continues to advance, we can expect to see more phones featuring infrared cameras in the future.
Are infrared cameras the same as thermal cameras?
Infrared cameras and thermal cameras are often used interchangeably, but they are not exactly the same. While both types of cameras detect heat signatures, infrared cameras typically use a different type of sensor to detect near-infrared radiation, which is just beyond the visible spectrum. Thermal cameras, on the other hand, use thermal sensors to detect and measure the temperature of objects.
Infrared cameras are often used in applications such as night vision, surveillance, and remote sensing, where the goal is to capture images in low-light environments or detect heat signatures. Thermal cameras, on the other hand, are typically used in applications such as predictive maintenance, building inspection, and medical imaging, where the goal is to measure temperature and detect thermal patterns.
Which phones have infrared cameras?
Several phones have infrared cameras, including some high-end smartphones and specialized devices. For example, some Cat phones, such as the Cat S62 Pro and the Cat S61, have built-in thermal cameras that use a FLIR sensor to detect heat signatures. Other phones, such as the Huawei P30 Pro and the Honor 20 Pro, have infrared sensors that can be used for applications such as temperature measurement and thermal imaging.
It’s worth noting that not all phones with infrared cameras have the same capabilities. Some may only have basic thermal imaging capabilities, while others may have more advanced features such as temperature measurement and thermal analysis. When shopping for a phone with an infrared camera, it’s important to research the specific features and capabilities of the device to ensure it meets your needs.
What are some common uses for infrared cameras on phones?
Infrared cameras on phones can be used for a variety of applications, including home inspection, predictive maintenance, and outdoor activities such as hunting and fishing. For example, a contractor might use an infrared camera to detect heat leaks in a building, while a maintenance technician might use it to detect overheating equipment. Outdoor enthusiasts can use infrared cameras to detect heat signatures of animals or track their movement.
In addition to these specialized use cases, infrared cameras on phones can also be used for more general purposes such as taking thermal selfies or detecting heat sources in the environment. Some apps even allow users to create thermal videos and share them on social media.
Can I use an infrared camera on my phone to detect thermal defects in my home?
Yes, an infrared camera on your phone can be used to detect thermal defects in your home, such as heat leaks, insulation gaps, and moisture damage. By scanning your home with an infrared camera, you can identify areas where heat is escaping or where there are thermal anomalies that may indicate a problem.
To get the most accurate results, it’s important to follow some best practices when using an infrared camera on your phone. For example, make sure to calibrate the camera according to the manufacturer’s instructions, and take multiple readings from different angles to get a comprehensive view of the thermal patterns in your home.
How accurate are infrared cameras on phones?
The accuracy of infrared cameras on phones can vary depending on the type of camera and the specific application. Generally, high-end infrared cameras on phones can provide accurate temperature readings and thermal images, but they may not be as accurate as specialized thermal cameras used in industrial or commercial settings.
To get the most accurate results from an infrared camera on your phone, it’s important to follow the manufacturer’s instructions and take the time to calibrate the camera correctly. Additionally, it’s important to understand the limitations of the camera and the specific application you are using it for.
Can I use an infrared camera on my phone for medical purposes?
While infrared cameras on phones can be used for some medical purposes, such as detecting skin temperature or tracking fever, they are not suitable for all medical applications. Infrared cameras on phones are typically not FDA-approved for medical use, and they may not provide the level of accuracy or detail required for medical diagnosis or treatment.
However, some specialized apps and devices are being developed that use infrared cameras on phones for specific medical purposes, such as detecting skin cancer or monitoring wound healing. These apps and devices are typically designed for use by medical professionals and are subject to strict regulations and guidelines.
Are infrared cameras on phones secure?
Infrared cameras on phones can raise some security concerns, particularly if they are used to collect sensitive information such as thermal images of people or objects. To ensure security, it’s important to follow best practices when using an infrared camera on your phone, such as only using the camera for authorized purposes and storing thermal images securely.
Additionally, phone manufacturers and app developers must also take steps to ensure the security of infrared cameras on phones, such as implementing encryption and secure data storage protocols. Users should also be aware of the potential risks and take steps to protect their privacy when using infrared cameras on their phones.
