What is a Thermal Drone?
A thermal drone is an unmanned aerial vehicle (UAV) equipped with a thermal camera that detects infrared radiation (IR) to measure temperature differences in the environment. Unlike standard cameras that capture visible light, thermal cameras visualize heat signatures, which makes them useful in various applications where temperature variations are critical.
How Thermal Drones Work
Thermal drones operate by utilizing specialized lenses and sensors to detect and visualize infrared radiation (IR), which is emitted as heat by various objects. The process involves the following steps:
IR Detection: The thermal camera's lens captures IR radiation emitted by objects.
Thermal Sensor: This radiation is processed by a thermal sensor, usually a microbolometer, which measures temperature differences.
Image Processing: The sensor's data is converted into a visual format, displaying different temperatures in various colors (e.g., red for hot areas and blue for cold areas). Advanced image processing algorithms enhance the clarity and detail of the thermal images.
Data Transmission: The processed thermal images are transmitted to a ground control system where they can be monitored in real-time by the drone operator.
Thermal cameras are often mounted on a gimbal to stabilize the image and allow for comprehensive area coverage. The gimbal ensures that the camera remains steady and can rotate to capture a full 360-degree view, providing detailed and accurate thermal imaging from various angles.

Space Blanket: A Mylar space blanket can block infrared radiation. It reflects your body heat back, preventing it from being detected by thermal cameras. However, prolonged use can cause heat to build up inside, making this a temporary solution.
Thick Woolen Blanket: Similar to a space blanket, a thick woolen blanket can provide temporary concealment by trapping body heat. It's less effective than a space blanket but can be useful in short-term scenarios.
Choose the Right Background: Blending in with environments that have a similar temperature to your body can help mask your heat signature. For example, staying near warm surfaces like sunlit brick walls or ground can be effective.
Warm Clothes: Wearing warm clothing can help reduce the contrast between your body heat and the environment. Covering exposed skin with cool dirt can also help, though it's a temporary measure.
Burn It Out: Creating multiple heat sources, such as setting small fires, can confuse thermal cameras by creating a complex thermal environment, making it harder to identify individual heat signatures.
Thick Netting: Using netting materials can disperse your heat signature, making it harder for thermal cameras to detect a clear image.
Stationary vs. Movement: Remaining stationary can make you less noticeable than moving, as moving objects are easier for thermal cameras to detect.
Can Thermal Imaging See Through Walls?
Thermal imaging cameras cannot see through walls. They detect heat emitted by objects and visualize temperature differences. Walls, especially those made of materials like concrete and brick, block most infrared radiation, making it impossible for thermal cameras to see through them. What these cameras can do is detect heat patterns on the surface of walls, which might indicate the presence of heat sources like pipes or electrical wiring behind the wall. However, the actual imaging of objects behind a solid wall is not possible with thermal cameras.
Can Thermal See Through Smoke?
Yes, thermal imaging can see through smoke to a certain extent. Thermal cameras detect infrared radiation emitted by objects, which allows them to visualize heat signatures even through smoke. However, the effectiveness of thermal imaging decreases with thicker smoke layers, as the smoke particles scatter the infrared radiation, making it harder for the camera to detect objects behind the smoke.
What is the Difference Between 12 Micron and 17 Micron Thermal?
The main difference between 12 micron and 17 micron thermal sensors lies in pixel pitch, which directly impacts image resolution, sensitivity, and overall performance of the thermal imaging device.
Key Differences
| Aspect | 12 Micron Sensor | 17 Micron Sensor |
|---|---|---|
| Pixel Size | Smaller pixels | Larger pixels |
| Resolution | Higher resolution | Lower resolution |
| Sensitivity | Detects smaller temperature differences | Less sensitive |
| Field of View | Narrower | Wider |
| Power Efficiency | Less efficient | More efficient |
| Cost | More expensive | More affordable |
12 Micron Thermal Sensors: Offer higher resolution and better image detail, making them suitable for applications requiring precise thermal imaging. However, they are generally more expensive and consume more power.
17 Micron Thermal Sensors: Provide a wider field of view and are more power-efficient, making them a cost-effective option for users who need reliable thermal imaging without the highest resolution.
