What Makes Infrared Cameras Great for Detecting Thermal Anomalies

Published on by Alex Banner

Construction sites are more and more relaying on early diagnosis of issues with the building capacity and performance as the best method to prevent any potential problems and delays with the project and thus avoid unnecessary costs. These days, among the most advanced tools for doing diagnostic tasks on a constriction site are thermal imaging cameras. Thermal imagining is a method that can help building technicians and engineering managers perform detailed monitoring on the construction process and troubleshooting on different machines and applications. It's particularly useful for the assuring the quality of construction of low energy structures and buildings.

What Makes Infrared Cameras Great for Detecting Thermal Anomalies

The main purpose of thermal technology is to detect and monitor infrared radiation which is basically the amount of heat emitted by objects, in this case the walls of the building. For instance, a wall should have a consistent temperature from top to bottom, but in some instances there are considerable differences in temperature which are known as thermal anomalies. These can occur due to bad design but usually most of the anomalies are accidental. By using a thermal imaging camera construction technicians can identify the exact location of heat leaks which cause anomalies in the thermal insulation of the building.


Designed for both instant diagnosis and detailed inspection thermal cameras are advanced devices that detect the heat emitted by a certain object by converting thermal energy into visible light. Their specialized software allows for accurate heat evaluation and report output. The final result is an image displaying the thermal variations of the object's surface. The process used for analysing the image is know as thermography, while the produced image is called a thermogram. The efficiency of a thermal camera depends on various factors the most important ones being its thermal sensitivity and the resolution of the detector. The resolution of the detector refers to the number of pixels of the image produced where every pixel comes with a particular temperature range associated with it. The smallest difference thermal variations that the camera is able to detect represent the thermal sensitivity.


To obtain the best results technicians should opt for a practical camera with easy adjustment options. One of the best model of thermal camera currently available on the market is the FLIR E4 infrared camera which comes with various adjustments and measurements modes, thus providing the highest level of precision and accuracy. This is an advanced point and shoot camera designed to make the process of temperature monitoring as easy and efficient as possible. The high resolution sensor and focus-free lenses deliver enhanced images, while the bright colour display provides easy and quick menu navigation. The thermal sensitivity of 150mk detects small temperature differences allowing the technician to efficiently identify hot and cold spots on the structure.


The URL (FLIR E4 infrared camera) features an advanced reporting software and detailed image analysis which give a comprehensive thermal report. The camera is easily portable and lightweight yet has a rugged construction that makes it very durable. It's powered by quality Li-lon rechargeable battery and has a great storage capacity enabling technicians to store up to 500 sets of images. With its advanced inspection capability, practical design and different measurement options the FLIR E4 infrared camera can take the process of thermal imaging to the next level.
