Looking for the right thermal camera is not an easy job. With all the available models, you can't make the right choice. Making the wrong one will leave you with nothing but expenses and subpar work.
But don't worry because this guide will help you find the best thermal camera for you. We will detail the things you need to know and where you can find the best one. By the end, you will know exactly what you need to purchase.
So, let's get started.
Understanding Thermal Cameras
A thermal camera is a device that detects heat instead of visible light. It works by capturing infrared radiation and converting it into an image that shows temperature differences. This makes it useful for spotting issues that are invisible to the naked eye, such as electrical faults, water leaks, or even animals in the dark.
Unlike regular cameras, however, light is not needed for thermal imagers. They can even operate under complete darkness, smoke, or fog, making them useful for various applications like security, firefighting, and house inspection.
Understanding how the camera works and its core features will also help you make the right choice. Let's now discover what you need to pay heed when buying a thermal imaging camera.
How to Choose the Right Thermal Camera?
Picking the right thermal camera can be overwhelming when you know nothing about how they work. Whether you need one for residential inspection, for hunting, for industrial use, or for security, the improper camera can give you inaccurate readings and your hard work for nothing.
To make the best investment, here are the things you need to prioritize the most:
Resolution: Clear is Better
Thermal cameras illustrate things through heat signatures, but not all will display sharp, detailed images. Resolution is the gauge by which the sharpness of the image will depend upon the camera.
- Low Resolution (80×60 or 160×120 pixels): Suitable for general applications like searching for leaks around your property or general use for the outdoors.
- Mid-Range Resolution (320×240 pixels): Suitable for professional residential inspection, electrical work, and routine upkeep.
- High Resolution (640×480 pixels and greater): For high-grade industrial, scientific, or military applications where small things matter.
Higher resolution means better accuracy, especially when detecting small temperature differences. If your job involves analyzing fine details, avoid low-resolution cameras as they may not provide enough information.
Temperature Range – Know Your Limits
A thermal camera's range is the range over which the camera can measure temperature. Select the right range for the job you need the camera for.
- -20°C to 300°C: Especially suitable for residential inspection, energy audit, and HVAC equipment inspection.
- Up to 650°C: Suitable for the measurement of overheat machinery, electrical faults, or automobile diagnostics.
- Above 1000°C: For processes like metalworking, smelting, and firefighting for industries.
A camera with a high-temperature range will provide you with greater flexibility, assuming you will use the camera for multiple functions.
Thermal Sensitivity – Feeling the Smallest Differences
Thermal sensitivity (NETD) is the measure by which the camera can sense very small temperature changes. This is essential for the inspection of insulation gaps, small leaks, or electronic overheating.
- ≥0.05°C (50mK): Ideal for professional use and high-resolution thermal imaging.
- ≥0.10°C (100mK): For general inspection where small temperature differences are not very significant.
If you need very sensitive temperature measurements, use one with high thermal sensitivity.
Field Of View (FOV) – Broad or Narrow?
The Field Of View (FOV) is the portion of space the infrared camera can perceive all at once.
- Wide FOV (i.e., 45° x 34°): Especially useful for sweeping over larger surfaces, such as building inspection, heat-leak detection, or security surveillance.
- Narrow FOV (i.e., 18 x 24°): Provides high-resolution, close-range thermal imaging. Specially suitable for the inspection of machinery, electrical panels, and small target spotting.
Choosing the right FOV will enable you to make the best possible use of your thermal camera.
Battery Life – Don't Get Caught Off Guard
A thermal camera will need to have enough battery life for your work not to need non-stop recharge.
- 2–4 hours: Entry-level models for residential use.
- 4–6 hours: Mid-range models for professional inspectors doing inspection or workmanship jobs
- 6+ hours with Replaceable Batteries: Ideal for industrial use, long-duration fieldwork, or emergency services.
If you're shooting remotely or shooting outside, use one with good battery life or replaceable cells to avoid lost shooting opportunities.
Display and User Interface – Readable and Usable
A high-quality IPS or LCD screen allows for easier analysis of the heat images. Even high-end cameras now allow for touchscreen operation for easier handling.
Look for:
- Large screen (3 inches and bigger) for good visuals.
- High brightness for daylight exposure.
- An intuitive interface so you will not struggle through settings when inspecting.
Connectivity – Saving and Sharing Images Made Easy
Modern thermal cameras also support multiple connectivity options for the convenience of transmitting images and reports.
- WiFi/Bluetooth: Allows for instant sharing to cell phones for real-time tracking.
- USB: Simple and secure for copying photos onto the computer
- SD Card Storage: Convenient when you require storing significant quantities of thermal data for analysis later.
For professionals, the WiFi-enabled cameras save you time by enabling you to send the results immediately to clients or colleagues.
Durability – Built for the Job
If you will be operating your thermal camera under harsh circumstances, choose one with a robust build that can withstand drops, dust exposure, and exposure to water.
- IP54 or greater guarantees dust and water spray protection.
- Shock-resistant housing guards against impact from accidental drops.
For industrial or exterior applications, you require a heavy-duty thermal camera.
Where to Buy the Right Thermal Camera
Finding the appropriate retailer where you can buy the thermal camera is also very important. An ethical seller ensures you get a high-quality camera, good customer support, and the best price.
