Buying Guide – Things To Consider

When deciding which is the best thermal camera for your needs, you should consider a few features that will enhance your experience with the product.

1. Temperature Range

Typically, the manufacturer of these devices will show you the minimum and maximum temperatures their products are accurately able to read. When it comes to these cameras that you attach to your Android device, they typically have a thermal sensitivity of between -4 and +248 degrees Fahrenheit.

When shopping for such compact devices, consider what the lowest and highest temperatures will be when you conduct an inspection.

2. Thermal Resolution

Thermal resolution is vital to consider because it helps you to quickly identify any potential problems.

Cameras with a low-thermal resolution will help you to find where the problem is but will not show the extent of the problem. Alternatively, thermal cameras fitted with a high-resolution camera can better identify how big or small the problem is.

A high-resolution camera will also provide a more detailed image or video. Choosing a camera with a thermal resolution of upwards of 120 x 60 pixels is best. However, the best would be one with a thermal resolution of 320 x 240 pixels.

3. Accuracy and Repeatability

You should look closely at the camera’s plus and minus temperature ranges. It is this feature that will help you to determine if there is a problem with your hot water boiler or not.

The readings given by these devices for heat detection purposes are generally provided to you in degrees Fahrenheit or Celsius.

Several factors are taken into consideration by these thermal cameras when producing a reading, and these will affect how the infrared energy being produced is read.

The factors that are taken into consideration include the following:

  • Ambient temperature
  • The camera’s response to the temperatures
  • The emissivity transmittance
  • Atmospheric temperature

The results produced by these devices must be repeatable, ensuring that the camera is more accurate.


How accurate is a thermal camera?

The accuracy of the readings provided by a thermal camera will differ from one make and model to another. But generally, you will find that the average one has an accuracy of between plus or minus four degrees Fahrenheit.

Can I use a thermal camera to see through walls or concrete?

Unfortunately, most thermal cameras do not have the capabilities to provide thermal readings through walls, concrete, or other hard surfaces. This is because these kinds of surfaces can block infrared radiation.

Can a thermal camera detect plumbing leaks?

Yes, this is one of the many ways this equipment can be used. It detects these kinds of problems by being able to read subtle differences in the temperature of the water in the pipe or where it is leaking from.


A thermal camera that you can connect to a smartphone isn’t just for use by professionals like plumbers or electricians. It can prove to be an effective tool that you can use yourself to help reduce repair costs to your home.

Whatever it is you need to check in your home, whether you think you have a water leak or a problem with your electrics, thermal cameras for Android devices can prove helpful in identifying hot spots.

Not only could these devices save you a lot of heartaches, but also a lot of money as you will be able to identify any problems before they get any worse.
