The Best Thermal Camera for Phones: A Buyer’s Guide

Thermal imaging cameras for smartphones have become increasingly popular, whether you’re a building inspector, DIY enthusiast, or simply curious about the invisible world of heat around you.

These handy gadgets can help detect electrical faults, energy loss, or even find a lost pet in the dark. Our in-depth guide will walk you through the essential attributes to consider, making sure you find the best thermal camera for phone use.

Resolution

Resolution stands out as a critical factor when picking a thermal camera for your phone. Just like with regular cameras, higher resolution means more detailed images. In thermal cameras, you’ll often see the resolution listed as a set of numbers, like 160×120 or 320×240.

The higher these numbers, the clearer the thermal image. For professional use, like detecting electrical faults or building inspections, a higher resolution is invaluable. However, if you’re just using it for fun or simple tasks, you might get away with lower resolution. Remember, higher resolution often comes with a higher price tag, so weigh your needs carefully.

Sensitivity

Sensitivity, or thermal sensitivity, refers to the smallest temperature difference the camera can detect. This is usually measured in millikelvins (mK). A lower sensitivity rating indicates better performance. For instance, a thermal camera with a sensitivity of 50mK can detect smaller temperature differences than one rated at 100mK.

If you need to find minute temperature changes in electrical components or insulation, a more sensitive camera will be essential. But if you’re just curious about general heat sources, sensitivity may not be as crucial. Make sure to consider what you’ll be primarily using the camera for when evaluating sensitivity.

Field of View

The camera’s Field of View (FOV) is another key aspect to consider. It determines how much of the scene you’ll capture in a single shot. A wider field of view is perfect for scanning larger areas, making it ideal for building inspections or landscape surveys.

However, if you’re focusing on specific, smaller objects or details, a narrower field of view might serve you better. It’s essential to match the FOV with your intended use to ensure you’re getting the most out of your thermal camera for your phone. Remember, you can’t zoom in on details without losing resolution, so choose wisely.

Compatibility

Compatibility can be a deal-breaker when considering a thermal camera for your phone. Not all thermal cameras work with every smartphone model, so ensure the camera you choose is compatible with your device. Most manufacturers will list compatible phone models in their product descriptions.

Furthermore, check whether the thermal camera app is available for your phone’s operating system, be it iOS or Android. Also, consider how the camera attaches to your phone. Some connect via USB-C or Lightning ports, while others might use WiFi or Bluetooth. A little research here will save you a lot of hassle later.

Refresh Rate

When evaluating thermal cameras for your phone, don’t overlook the refresh rate. This is typically measured in hertz (Hz) and indicates how often the camera updates the image. A higher refresh rate will result in smoother images, which is vital if you’re dealing with rapid temperature changes or moving subjects.

Most consumer-grade thermal cameras offer refresh rates between 9Hz to 30Hz. A higher refresh rate will usually mean a higher price and might be subject to export restrictions. Consider your needs: if you’re in fast-paced environments, a higher refresh rate will be very beneficial.

Battery Life

Battery life might not be the first thing you think of, but it’s definitely important. Some thermal cameras for phones draw power directly from the phone, while others have their own batteries. If your thermal camera relies on your phone’s battery, expect your phone to drain faster.

On the other hand, cameras with their own batteries can operate independently, giving you more flexibility. Check how long the camera can last on a single charge, especially if you’ll be using it for extended periods. A camera with a decent battery life or efficient power consumption will save you from constant recharges.

Price

Last but certainly not least, let’s talk about price. Thermal cameras for phones can range from under $200 to over $1,000 depending on the features and specifications. While it might be tempting to go for the cheapest option, remember that you often get what you pay for in terms of image quality and functionality.

Think about your budget and what features are most important to you. For occasional use, a mid-range thermal camera might suffice, but for professional use, investing in a higher-end model could save you money in the long run by providing more accurate and reliable data.
