Drone Thermal Camera Reviews

THERMAL CAMERAS FOR DRONES

‘There’s more to it than meets the eye’. How many times have you heard this phrase? If you’re familiar with the concept of thermal imaging then you’re aware there’s only so much the naked eye can see. 

Visibility is impaired in certain situations for instance at night. But that doesn’t mean there’s nothing happening in the invisible spectrum. Thanks to thermal imaging cameras certain important but hidden aspects are brought to “light”. And then add that to a drone. The drone thermal camera innovations can transform TIC applications.

Below we review some of the best ones. But how exactly does the technology work?

What is a Drone Thermal Imaging Camera?

You’ve heard of a thermal imaging camera but what exactly happens when you combine that with a drone? Here’s a definition that might assist:

  • Drone: A drone is a technologically equipped device that can hover and fly overhead. A drone can be fitted with smart technology such as GPS navigation and infrared cameras.
  • Thermal imaging camera: This is a camera that can detect objects or hotspots in dark environments which can be impossible to detect with the naked eye or a visual camera. It detects infrared radiation and temperature detection to locate an object or person. This is slightly different than night vision cameras that magnify the light; in contrast, thermal imaging cameras use infrared detection to create images.

How Does it Work?

Did you know: All objects absorb, reflect and transmit energy at different levels. While the ordinary human eye can’t pick up this energy, specialized infrared equipment can detect this energy and display it as an image.

Thermal imaging cameras see through darkness and ignore visual camouflage. Also they need no light whatsoever to produce a clear image. So how then do they produce it? They rely on emitted heat instead of light to create an image.  

This is done by recording minute differences in the heat emission temperatures and translating that information into a visible image. Because they rely on thermal instead of visible contrast it means they’ll provide perfect vision even when darkness renders normal eyesight useless.

Drone Thermal Camera Uses:

Drone thermal imaging cameras are particularly useful in these instances.

Building Inspections:

By focusing this camera on the roof of a building, technicians can see where thermal insulation is faulty. Apart from detecting overheating circuits and heat leaks they can also determine how effectively a roof is insulated. 

Having this information helps them fix any problematic wiring and consequently prevent power surges. End result - safer buildings.

Farm Inspections:

Thermal imaging camera sensors help farm owners manage crops, soil, fertilizing and irrigation effectively. How? The cameras use infrared wavebands to capture both visible & invisible images of crops and vegetation. Identifying the health of soil & crops with the naked eye is very limited. Drone cameras allow farmers to see further than the naked eye and gather more data by:

  • Identifying pests, diseases and weeds
  • Providing data on soil fertility by detecting nutrient deficiencies
  • Locate livestock at night 
  • Count plants and determine spacing issues

Electrical Line Inspections:

Power line maintenance technicians use drone thermal camera setups to locate overheating joints & parts to eliminate potential power failures.

Safety:

Even citizens benefit from use of these cameras where safety is concerned. How? Law enforcement uses them to:

  • Manage surveillance activities
  • Locate and apprehend suspects
  • Investigate crime scenes
  • Conduct search & rescue operations

Fire Fighting:

As mentioned earlier this concept allows for improved visibility in dark or visibly impaired environments. As a result fire fighters use them to see through smoke and consequently find people in need of rescuing. Also it helps them localize hot spots of fires so they know where they need to be.

Hunting:

Ask any serious hunter and they’ll tell you many animals are mostly active at night - using darkness to remain undetected. Unfortunately they can’t hide from the drone thermal imaging camera. Why? All warm blooded animals will show up clearly in the thermal image, regardless of intensity of darkness or weather conditions.

Additional Buying Information:

1. Resolution & HD:

Ideally the most effective camera must have both high resolution thermal and high definition color imaging integrated into one if you need clear images for your work.

2. Wide Field of View:

This is the extent to which your camera can see and it’s measured in angles. Angles between 140 to 170 degrees are quite impressive.

3. Video Stabilization:

The last thing you need is a shaky video. Make sure you pick a camera with stabilisation if most of your footage will be recorded in video mode as opposed to still pictures.

4. Video Quality:

The quality determines how clear and smooth the video is. Pick a camera which uses real/native resolution and a frame rate of at least 30fps for clear videos.

5. Durability:

Because your drone will be venturing into all sorts of weather conditions, in dire circumstances it might end up on the floor or worse - shredded into pieces. You don’t want to lose your footage if this happens. To avoid this, a weather & shock proof camera is ideal.

6. Weight:

If it’s too heavy it’ll affect the drone’s center of gravity and it won’t fly properly. Simply put: the lighter, the better.

Drone Mounting

How you mount your drone will depend on whether it’s compatible with the camera or not.

Compatible with Action Cameras

For this one simply pop it in the frame or attach it on the mount.

Not Compatible

To mount your camera to your drone you can either buy a Gimbal or DIY kit.

  • Buying a Gimbal: A gimbal is a device you attach to your drone then to your camera. It stabilizes the shot your camera records. Your camera must come with mounts which you connect and tape on the bottom of your drone. After this you can use Velcro or Zip ties to secure it in case the tape gives way.
  • DIY: If it doesn’t come with mounts use Blue tack or Zip ties. You simply place it at the bottom of the camera and you’re good to go.

Final Thoughts:

The support the thermal drone affords to industries such as agriculture, construction, public safety, and real estate is revolutionary. It has completely transformed how professionals in these industries plan and execute their tasks.

The usefulness of a thermal drone like the Parrot Anafi Thermal can't be ignored any longer if you want to succeed in your profession. Of course, it's not only used in a formal setting but offers enjoyment to the avid hunter, dedicated photographer, and tech enthusiasts.
