Choosing a Thermal Imaging Camera for Fire Service and Firefighting: Factors to Consider

Given the very important benefits associated with the use of thermal imaging cameras, firefighters all over the world are adopting this technology in their daily tasks.

Therefore, there is need to choose the correct thermal imaging camera in order to make sure that they can serve the daily needs of firefighters.

Let’s look to the 11 factors below that should be considered when choosing a thermal imaging camera for firefighting or fire service.

As additional resource, you can check out thisPerformance Metrics for Fire Fighting Thermal Imaging Cameras” by the National Institute of Standards and Technology (NIST).

1. Durability

Durability is one of the most important factors that should be considered when one is looking forward to buying a thermal imaging camera for firefighting. When putting out a fire, firefighters are usually in very harsh conditions, which means that your camera too will be subjected to the same harsh conditions.

In order to be sure of the durability of the camera, you need to pay attention to the information provided about the drop, shock, heat and water test results. These tests are actually the conditions that the firefighter may go through when trying to put out a fire and to rescue victims and items. Therefore, you need to evaluate several different models, and most especially consider the test results that have been provided by the manufacturer.

2. Features

Different models of thermal imaging cameras can have different features. However, you may find there are cameras that have the same features installed in them, but they differ in their implementation, for example, certain features such as high heat colorization and temperature measurements are installed in all thermal imaging cameras, however, their implementation differ from one camera to the other.

Certain features such as the color scheme help to provide results at different temperatures. The color scheme increases when it reaches a certain temperature threshold or decrease when the temperatures start decreasing. Also, there are other models that allow the user to adjust or simply change the color scheme at different exposure to heat.

3. Image Quality

This can be termed as the most important factor that you should consider when buying a thermal imaging camera for firefighting. Every firefighter knows the importance of having a camera that has a great image quality when they are going about their operations. They definitely know that they want something that is very powerful and not something that will give them a poor image quality.

If the picture is very clear, it becomes easier for the firefighting personnel to perform their activities. More often than not, you will hear firefighters saying they want a camera with a great screen that will provide the clearest displays. For you to evaluate the image quality of a TIC, several tests should be done in various different situations, including outdoors, indoors and in environments subjected to high heat.

The imaging performance details of a thermal imaging camera can be tested on various aspects. The imaging performance metric of a TIC can be shown on the following factors:

• The contrast: A contrast test is done in order to identify the maximum possible contrast that can be displayed on the screen of a thermal imaging camera.

• Uniformity of the image: Here a uniformity image test is done to evaluate the ability of the thermal imaging camera to display an image that is perfectly uniformed.

• Effective temperature range: the temperature shows the minimum and the maximum temperature a thermal imaging camera is able to measure. A temperature test is usually done which provides an effective temperature range. The results provide useful information to firefighters when choosing the correct TIC for their activities.

• Thermal sensitivity: A thermal sensitivity test is usually done at different temperatures in order to identify the smallest temperature difference that can be shown by the camera’s display screen.

• Spatial Resolution: the results provided after a spatial resolution test is done usually shows the level of detail that is provided by a thermal imaging camera.

4. Built-in Visible-light Camera

When any firefighting personnel is going about the firefighting activity, they all know the importance of having a tool that does not interfere with their activity or convenience. You don’t have to carry an extra tool along your thermal imaging camera in order to capture the spots that you want to capture in order to perform your rescue better.

There are so many models of imaging cameras that come have a built-in visible light feature that helps to simultaneously capture a thermal image and a visible light image. This provides more detailed images even those that have been taken in darker areas.

Therefore, you the user will be able to provide a detailed report about the situation and also share with others. There are those with built-in laser markers that makes it able for the camera to show the difference between the target spot surrounded by other components that look similar to the spot, thereby showing a problematic electrical equipment that is emitting energy which you need to keep some distance from. The built-in laser markers provide reliable information too.

5. Form Factor and Weight

When it comes to choosing any tool for firefighting, considering its weight and size is very important. This happens also when choosing a TIC. There are those thermal imaging cameras that are smaller and lighter can easily be held in a palm of your hand. The smaller ones may have smaller displays. There are also the larger ones which have larger displays and have handles to allow the user to hold it better. TICs may have side straps or handles, while others may not have the straps.

6. Ergonomic Features

Some thermal imaging cameras have ergonomic features that improve their ease of use. Those that have interactive controls, like the direct access menus and dedicated buttons are usually the most popular.

You will need to choose a thermal imager that has more buttons that are well positioned so that it becomes easier for you to access the options that you want, rather than just relying on one button. There are those models that have integrated touch screens which are meant to improve your access to the options or features.

7. Maximum Operating Temperature and Temperature Range

The temperature range of a thermal imaging camera is very important and should always be considered when buying one. To identify the temperature range of a TIC, a temperature range test is done at different temperatures and the results are provided by with the manufacturer.

The temperature range shows the minimum and the maximum temperatures that a thermal imaging camera can measure. For fighting activities, you will need to select a temperature that is wide enough in order to capture all of the images at different temperatures.

8. Accurate and Repeatable Results

TICs are able to provide the differences in heat by actually measuring those differences. Therefore, you will need a camera that can provide accurate and consistent measurements. The accuracy and consistency of the measurements are very important factors that you should consider in order to buy a thermal camera for firefighting.

For accurate and repeatable results you will need a thermal imaging camera that has some inbuilt tools that allow for entering both emissivity and displayed temperature values. A thermal imaging camera that meets or goes beyond plus or minus 2% accuracy will provide good image that a firefighter may need.

9. Storage and Output Supported by Standard File Formats

A thermal imaging camera that is able to store the captured spots is a good camera, however, that is not enough because you may need to transfer the images to a computer and share them with others. Therefore you will need a camera that provides an output that is broadly supported by standard file formats. There are those models that provide images in JPEG but they may lose temperature information. Some models may have the same JPEG storage capacity but with full temperature analysis integrated, thereby, you will be able to share the images without losing vital temperature information.

10. Reporting Software

A reporting software is a good factor to consider when choosing a thermal imaging camera for firefighting. Most fire departments want models of TICs that have a software which allows them to perform proper image analysis in order to create reports that are simple.

11. Value-Added

You need to consider the length of the warranty of a thermal imaging camera and the service repair times as well. You need to compare the warranties of different manufacturers so that you can get the warranty in terms of coverage and value. The warranty of a TIC can help you make the final decision after considering all the other factors.
Considering the above important factors will help you buy the correct thermal imaging camera for firefighting that meets your need. However, you will need to have a better understanding of how to use the camera in order to go about your activities better.
