Infrared Cameras, Thermal Cameras, Thermal Security Cameras or Thermography Cameras – What Are the Differences and Which One Do I Need?

Thermal Cameras, Thermal Security Cameras and Thermography Cameras – What Are The Differences and Which One Do I Need?

By Tjaart Broodryk

Broadly speaking there are really two main types of Infrared Cameras, and then a third although the third is not that important in the mainstream marketplace. The three main types then are:

THERMAL IMAGING or THERMAL SECURITY Cameras – Cameras that are designed to output an infrared image only – these cameras cannot measure temperature.
THERMOGRAPHY CAMERAS – Cameras that output a Radiometric infrared image and can measure temperature or quantify electromagnetic radiation in several different units.
SCIENTIFIC INFRARED CAMERAS that allow users an open framework camera, necessary for Advanced Radiometry and allows total access to the setup, calibration and outputs of the camera.

Main uses of these cameras (there are off course more) in the mainstream are:

THERMAL IMAGING or THERMAL SECURITY Cameras that cannot measure are used for security / military purposes, or similar applications such as hunting – where detection is key and temperature measurement just does not matter.
THERMOGRAPHY CAMERAS that can measure are used for maintenance or condition monitoring purposes or similar where detection of heat radiation differences and the temperature are important.
SCIENTIFIC INFRARED CAMERAS – for users mainly in Research and Development applications where radiometry, accuracy, frame rates or camera speed and synchronization requirements are key.

Optical Gas Imaging (OGI) detects gas leaks, a fairly recent development in thermography camera development, possibly a new category camera on its own and is not discussed further here. If you need any information on Optical Gas Imaging Cameras, please contact our team directly.

The internet, however, has become slightly confused, and mainly because the terminology to distinguish between these main types of infrared cameras have not been standardised – not between OEM’s and not even internal to OEMs.

Point and shoot thermography camera — Entry level Thermography

Not that this matters much to users looking for security or personal use Infrared cameras – where the bulk of the market sits today. It does however matter a lot if you are looking for a camera that can measure temperature (accurately) and produce a report from captured data. Searching the web when you need something other than a straightforward Thermal Imaging camera can be frustrating as terminologies are used incorrectly by suppliers that do not really know or care

There are few people / companies out there that know enough about Infrared Cameras to be able to explain the differences, and even fewer that can accurately match your needs to a specific model. Infrared Camera prices will range from cheap to very high, buying wrong happens daily. There are literally thousands of Infrared Camera models available, and even more OEMs and distributors arrive daily.

The differences and the specifications between the main types – and then between the models of each type are not always clear. Save to say that there is a nice and confusing bunch of specifications that accompany all three types of cameras. I will not go into the specifications here – that is saved in a future blog – and I am not an expert on the security type cameras, but when it comes to Thermography cameras, we know a lot. Which specifications matter? And why? Look for a future blog here or call us today if you need to know right now!

Latest Generation FLIR Handheld Security camera
“Professional Thermal Monocular”

This article aims to quickly give an overview of the three main types of cameras, the trick is that if you are going to use the camera for professional services – not so much personal – then buy from the supplier that has best knowledge, offers training and can support these cameras with spares and calibration services for at least the warranty term – which with FLIR Cameras is up to 10 years!

The difference between the three types of Infrared cameras lies mainly in their intended end-use, features, and application environments, even though all three sense and convert infrared radiation (heat) rather into a visible light image.

I am not going to elaborate on types of detectors, spectral ranges, temperature ranges, speed or optical specifications. This article is intended to highlight the basic differences only for users who need a quick guide around the type of Infrared Cameras available. Below are a few tables intended to summarise this text and to give a little more information in bite size chunks.

USD$ 1,000,000 savings on a primary crusher
Optimizing Lubrication Management with Advanced Predictive Maintenance.

Previously, traditional predictive maintenance tools failed to detect early bushing damage in a primary crusher, resulting in a catastrophic $1,000,000 failure. To enhance their lubrication management, the customer integrated Atten[2]’s OilWear S sensors after a thorough assessment of predictive maintenance technologies.

Before this, lubrication cycles took over a week, requiring sampling, lab analysis, and decision-making. With the new sensors, real-time monitoring now streamlines maintenance, reduces downtime, and improves equipment health.

Download Case Study

CHALLENGES:
- Short time interval from start of damage to catastrophic machine failure
- Damage difficult to detect with conventional monitoring technology
- Possible mistakes during oil sampling
- Long response time of the lab
SOLUTION:

Given this customer’s needs, Atten[2] recommended the installation of OilWear S sensors. The ISO code display and real-time particle shape classification enabled quick decision-making:
- The lubrication management cycle went from one week to one or two days, reducing risks in sampling, reducing lab and labour costs, and thus increasing machine lifetime.
- The sensors also optimized asset management and prevented a catastrophic failure that would have shut down the mine production.
SEQUENCE OF FAULT DETECTION

May 20th, 2021

“Baseline” of primary crusher operation was set to an ISO code 22/20/19, as seen in the box, the average data before the failure began.

May 22nd, 2021

At the precise moment when the values showed a notable deviation, increasing beyond the normal ISO code (24/23/21), an increase in sliding wear was detected.

Armed with this information and mindful of the previous catastrophic bushing failure, the operator conducted on-site inspections, leading to the discovery of a fault in one of the bushing.

* Note: The increase in fatigue wear (natural wear) is not in itself an abnormality that requires attention!

May 23th, 2021

The graph shows a sustained upward trend in the ISO code (25/24/22). Similarly, the classification of particulate matter indicates a continuous increase in cutting and sliding particles.

To stabilize the crusher’s performance, several corrective actions were implemented, including partial lubricant changes, enhanced lubrication practices (such as lifting and balancing the bushing with additional oil supply), reducing the machine’s operating speed, and maintaining frequent filter replacements.

June 06th, 2021

Thanks to continuous monitoring, an issue with a bushing was detected, associated with the presence of cutting and sliding particles deviating from normal operating parameters. Without Atten[2]’s imaging technology and shape analysis, detecting this damage in time would have been impossible or very difficult. The ability to provide reliable measurement results even with high oil viscosity and strong bubble formation in lower ISO classes, compared to con-ventional particle counters, is another key advantage that enables early damage detection under harsh conditions as given here with this particular crusher.

Prompt actions were taken to rectify the situation, allowing production to proceed as planned. On June 6th, 2021, corrective measures were implemented during the scheduled plant shutdown, replacing the bushing. After the crusher’s startup process, it returned to its established ‘normal line’ of operation, indicated by the ISO code (22/20/19). During the monitoring period, a bell-shaped curve in fatigue particles was noted, a typical phenomenon linked to the machine’s startup phase.

CUSTOMER ́S BENEFITS

An unexpected failure in this type of machine significantly impacts the mine’s operation, leading to substantial production losses. Atten2 technology played a crucial role in early fault diagnosis, allowing timely decisions and actions to prevent a catastrophic breakdown. This proactive approach not only extended the machine’s lifespan until the next planned shutdown but also helped the mine avoid potential failure-related costs amounting to USD$1,000,000.

This same event occurred years ago at the primary crusher, resulting in the customer reporting losses and expenses of approximately one million dollars. This includes direct costs of production hours and expenses associated with the shutdown.
