What is IR Thermal Imaging Camera?

Based on body heat, every object in the universe emits infrared energy and that emitted heat or infrared energy is taken as its signature of heat. This emitted energy increases based on the body heat of an object.

A thermal imager often called Infrared Camera is basically a heat vision sensor that uses thermal imaging technology which can detect very little differences in the temperature without any ambient light even in extreme darkness.

The temperature camera receives the overall heat energy from the objects in the screen and produces an electronic image based on the collected temperature information. Other thermal devices like thermal scopes, thermal monoculars, thermal imaging goggles, and thermal binoculars are also working based on this technology.

A thermal image camera can detect each individual object in the scene and create different thermal images if there are any temperature abnormalities due to leakage in the objects or living beings hidden in the scene. These heat sensitive cameras are used to figure out the temperature differences and heat leaks in buildings and electronics. There are thermal imaging security cameras used in home and industries to ensure the safety. They are also used in army and hunting.

How much does a Thermal Camera cost

You have many valuable thermal imaging cameras within $1000 whereas you also have the thermal cameras that offer basic thermal imaging features for as low as $250. The thermal imaging add-ons for mobile phones are available from $100 to maximum of $500. The best thermal imaging camera brands such as Seek, Flir, Fluke, and Dewalt are pricing up to $3000.

What Makes It Expensive?

The thermal imaging cameras are priced according to the features they come with. Apart from the basic features such as the temperature range and sensitivity, thermal imaging camera cost varies with respect to the infrared resolution, multiple modes, touch screen display, battery life and other advanced special features they have equipped with.

Based on the cost of thermal imaging camera you can divide the brands into two classes: Thermal cameras with many additional features and a wide range of benefits that costs high and those cameras that are built with basic thermal imaging features that cost less.

Renting VS Owning

Below are some of the advantages of owning and renting a thermal camera.

Advantages of Renting

The most common reason why people renting a camera is “It’s cheaper”. If you have a limited budget and will need a camera for very particular uses then you can rent a camera from the best Renting companies. The rented thermal camera offers you the same qualities and features what an owning one will provide but for a short period.

Another advantage of renting is you can try out different brands and products with which you will get the experience and knowledge about the thermal camera and what are all the features you are requiring. This will helps you when you planned to own a thermal camera.

Advantages of Owning

If you are a frequent user of the thermal camera for your regular home inspections and any repair jobs, you could own a camera instead of renting it adequately.

Owning a thermal camera will help in any emergency situations. Imagine that you feel sudden heat increase in your darkened basement and you are not sure what would be the cause. In this case, you can’t take the risk of getting into the basement only with a torch, here you will need a thermal camera at least to have the guts to look into.

So these are all the advantages of renting and owning a camera. You have to decide based on how often you will need it and how much you can afford.

What Are The Types Of Thermal Imaging Cameras?

The thermal imaging cameras are classified into two different categories depending upon the temperature they require for working; the thermal cameras with cooled infrared detectors and the uncooled infrared detectors.

Cooled Detectors Thermal Camera

The cooled thermal imaging cameras require cold temperature for operation. The temperature can be 4K or below in order to get benefitted with the infrared sensitivity. Using this type of camera will offer you crisp and clear images with great quality. However, they are a bit expensive and heavy.

This picture shows very fast capture result of a tire rotating at 20mph captured by the cooled detector.

Uncooled Detectors Thermal Camera

The uncooled detectors require an environment with the room temperature to perform the operation. They do not necessitate additional equipment for working. The quality of the images produced by these detectors is low when compared to the cooled detectors images. But, these are cheaper than the cooled detectors.

This picture proves uncooled detector has very low capture rate when capturing the rotating tire.

Irrespective of their type, both the cameras use a single color channel for visualization. They reproduce the object with different shades of colors to denote the temperature of the particular object or body. They represent the warmest parts of the object with bright colors, usually white.

The areas that are not hot are represented with yellow and red colors. Further, the areas with the coolest temperatures are represented in the darker color shades particularly black. It also displays the color scale depending on a particular temperature.

The difference between cooled and uncooled thermal imager in various fields of areas and applications are explained here. For further more technical details about the types of thermal cameras, check out this Wiki page. 

Handheld Thermal Imaging Camera

Thermal imaging cameras are available in different shapes and sizes. The handheld thermal camera helps to do the thermal survey for a long time just by holding them in one hand. The shape of the device is similar to the Infrared Thermometer which is used to find the body temperature.

US national library for medicine uses thermal cameras in the reconstruction of lower limb after skin cancer surgery. Some of the other applications of thermal imaging cameras are detecting the heating parts of complex mechanical devices, finding heat loss or gain in the skin, veins and other body parts of animals to treat them, doing non-contact temperature analysis of confusing electrical tools and machinery, and helping security and police officers to trap and find the criminals in critical climatic conditions.

Thermal Imaging Cameras for HVAC/R

Just as with the normal electrical and mechanical applications, today’s thermal cameras with simple use and affordable price allow them available tool to use on other applications such as HVAC/R (Heating, Ventilation, Air Conditioning, and Refrigeration) industry.

A thermal camera sees the HVAC air flow.

Thermal imaging cameras are now used to find the leaking pipes, improper circulations in engine radiators, pipe disconnections in floor heating systems, defects in electrical and mechanical parts, poor airflow and temperature diffusion in the frozen cabinets.

HVAC/R unit is used to ensure the safe environment in terms of humidity, ventilation, and temperature. This is needed by an occupant to live in an acceptable environment with health and comfort and also make sure the health of the building and reduce energy costs.

In energy surveys, checking surface temperature becomes a major part as the surface temperature value can help to find the current condition of the building, HVAC/R, plumbing, mechanical and electrical.

Hence, blocks in pipes, air leakage, structural deficiencies behind the walls can be detected and recorded using thermal imaging camera.

Now, the periodic maintenance of HVAC/R unit becomes usual in many industries where they developed various strategies to monitor all the features of units from piping, plumbing, motors, radiators, engines, and bearings.

Thermal imaging camera for the HVAC/R system is easy to use and provide understandable pictures about where the issues are. This is important if you are working on HVAC/R and you need to prove your customer that you have fixed the heat or temperature problems.

Some of the various applications of thermal imaging camera on HVAC/R system are listed below.

In Air Ducks

  • Find leaks at joints
  • Identify the insulation loss

  • Find overheated connections

Thermal Imaging Cameras for Roofing

In the roofing industry, thermal imaging technology helps to find the wet insulation in the flat roofs and fasten the search of the leak source.

Thermal imaging camera detected the hotspots of insulation in the roofs.

Infrared camera for roofing is an excellent way to find the problematic wet areas in roofing systems. This minimizes the cost of replacing the entire roofing system by detecting the heat spots or leaking areas and allowed to fix those particular areas. The Infrared scanning for roofing system able to quickly estimate the durability of the roof without destructive testing.

Why Thermal Imaging for Roofing is Important

Let look into the valuable reasons why thermal imaging for the roofing system is important.

» Safety

The roofing system can get corrode or damage due to the moisture which will compromise the structural integrity of the roof. The rusted roof affected by the hidden trapped moisture would be a serious safety problem for workers working on the roof.

» Damage to other systems

The roofing system with water intrusion also damages interior parts due to leaks. With no wait, this will affect the other electrical and mechanical systems in the building.

These roof leaks also hit the contents of the building and collide the operations.

The strong formation of mold is possible in the roofing system because of the trapped moisture.

» Cost Savings

The replacement of the roofing system is expensive. The regular infrared monitoring of the roof is a cost-effective way to check the roof for health and issues. As thermal scanning is easy to use and take less time, it helps to repair the parts quickly and avoids the replacement.

How Roof Thermal Imaging Works

Thermal imaging camera spot the heat energy generated by the moisture in the roof and project the different radiations levels.

When compared to other parts of the roofing system, this trapped moisture takes time to cool so they can be seen on the infrared camera.

Thermal imaging cameras detect the heat energy radiated from the roof surface and other surrounded objects in real time.

The IR thermal camera identifies the heat signatures over surfaces by detecting the IR radiation of objects and processes it into visible light.

Types of Thermal Roof Imaging

Thermal roof imaging should be done on right conditions to get the accurate results. Based on these conditions there are two types of Thermal Roof surveys.

⇒ Warm Weather Scans

Warm weather scan used to check the temperature difference between wet and dry roof insulation.

This scanning process usually held after the sunset. The roof gets heated by the sun during the day thus the wet insulation also heats. After the sunset, except the wet areas, the other dry areas get cooled. So you can see the wet areas as ‘hotspots’ on the thermal camera.

⇒ Cold Weather Scans

Cold weather scan is usually done on an early morning before the sun heats up. This survey is held to find the difference between outdoor and indoor temperature.

Wet roof insulations have a thermal conductivity higher than the dry insulation so when the inner building is warmer than the outer, the wet insulation will pass more heat out of the building than the dry roof insulation.

Thermal Imaging Cameras for iOS

Thermal imaging for iOS devices is possible with Special Thermal Imagers that can be attached to the smartphones and accessed via mobile application. The first thermal imager for smartphones was FLIR ONE which is the mobile add-on device that can be used in Android and iOS devices like smartphones and tablet.

After FLIR, Seek thermal imagers are popular among users using thermal imaging on phones.

Though these thermal imagers are not as perfect as the featured thermal cameras, they have the ability to provide accurate thermal detection that can be used in home inspection.

What Are The Criteria That Should Be Met By The Best Thermal Imaging Cameras?

As there are various features and capacities built with a thermal imaging camera are varying brand to brand, selecting a particular camera becomes a complex task. However, you have to look into some basic features in any of thermal camera before choosing for any purpose.

Image Modes

The primary work of thermal imagers is to produce the thermal image of a suspected object. Most of the thermal cameras from a few years back have come with a feature of providing only the visual images which can help in identifying the defect in a particular location clearly. But now the thermal cameras have comprised of a unique mode called the fusion mode, with which both the thermal and the visual images can be obtained and it will help in identifying the problem and get the clear temperature information about it.

Picture Quality or Resolution

As the thermal imaging cameras are used to identify the defect or fault in a particular area, having a clarified picture with quality is essential. The resolution is determined with the help of the Focal Array Plane sensors present in the thermal camera that are not available in the digital cameras and is measured in pixels.

Purchasing a thermal imager with low resolution will result in a visual image which looks similar to the one from the digital cameras. Most of the thermal imagers offer a picture resolution capacity of 120×120 or 140 × 140 in terms of pixels. The best thermal imager will offer a resolution of 180×180 pixels thereby providing accurate images which are useful for detecting even the minute defects.

Screen and Display

Most of the cameras come with a screen size of about 3 inches which is good but the camera that has a screen size ranging between 5- 7 inches in size and are highly capable of displaying images with the higher quality. Higher the screen size, greater the accuracy and enables easy identification of the problems and defects. We recommend screen display size no smaller than 3 inches.

The next important feature of the display is the refresh rate. In general, the thermal imagers come with a refresh rate of 9 Hz and 60 Hz. Choosing the 9 Hz thermal camera is not a bad idea though the thermal camera which comprises of the 60Hz refresh rate is the best option as it enables proper focus.

Accuracy and Sensitivity

The thermal imaging cameras, with their infrared detector arrays are capable of offering accuracy with temperature sensitivity up to 0.1°C which is useful in detecting more accurate information. However, thermal imagers with the -20°C to 350°C temperature sensitivity and delivers precise measurements are considered extraordinary.

User-friendly

Usually, the cameras can be operated with the help of the buttons and triggers they are built with. A user can navigate through those menu buttons to the required function or operation they wish to perform.

The normal cameras may constitute only a few buttons and make the functioning get complex, whereas the best thermal cameras will constitute of several buttons with an intuitive menu, each of which is coded to perform a specific operation and are capable of navigating easily to the desired functions.

Battery

The capacity of the battery to hold the power, as well as the availability of the spare battery, is quite essential criteria that have to be considered before purchasing. A thermal imager’s battery should be easily removable and replaceable when it runs out of power. We would not recommend going with thermal cameras with inbuilt batteries that cannot be removed and result in depending upon the power cord or circuit.

When the lifetime of the battery ends, it has to be sent to the service shop and be checked for the availability of the replacement. But, the best thermal heat camera will have the removable Lithium-Ion battery and is readily available for replacement and holds the power for a maximum of 5 hours.

Durability

Thermal heat cameras, regardless of the field they are used in, has to be light in weight and compact to be held in a single hand. Only then, the user will be capable of using it for a longer period of time.

Further, the cameras should also come with a dust resistant cover and should have an exterior that is made of materials that offer grip in order to hold it in continuous working hours.

Image Format

The format that the image gets stored in the camera has to be considered while purchasing the camera. Generally, the thermal imaging cameras use two types of image formats; JPEG and BMP.

The BMP image formats will strip down the temperature information to preserve them and for sharing separately. In the cases of purchasing a camera with a BMP image format, you will have to face compatibility issues as most of them require software to convert them into the readable form. This will make the process of sharing to become complex and tedious.  But, those with the JPEG format are compatible with almost all the devices as it can be transferred and shared easily when at the workplace itself.

Image Storage

When in work, you will require downloading more and more images of visual, thermal and fusion types. The best thermal imaging camera with the higher resolution obviously consumes more space to be stored in the camera which will, in turn, hang the camera when the memory gets filled. This will result in cleaning up space often.

But with using a camera that has more than enough memory for storage will reduce the strain of deleting the images often to create space.

Visibility

The thermal imagers should be capable of producing images under any lighting conditions so as to be the best product. In the case of low light or darker areas, using a camera without proper vision will not help in identifying the defects properly. So, the best thermal imaging camera brands have come up with the option of including the thermal illuminator light which will help in providing images with picture clarity.

In A Nutshell

The thermal imaging cameras are such devices that use thermal imaging technology to visualize the defects in the pile systems, wiring, or any other places. They have a wide range of applications in almost every field. Thermal imagers work with the help of the detectors that are built with it and with respect to which the temperature they are capable of working with depends on upon.

When purchasing a thermal image camera for usage, you have to consider all the above factors and choose the one that has the most reliable qualities. Consider purchasing a product only according to your needs and necessities which will prevent you from spending extra bucks.
