Infrared Camera and Thermal Imaging Camera Reviews by Experienced Infrared Thermographers
Thanks for visiting infraredcameras.net.au, This site is dedicated to the review of ALL the major brands of thermal imaging systems on the market. Our Chief Editor, Brenton Ward is a level III Thermographer with more than 15 yearsexperience in thermography. Brenton provides thermal imaging services in Australia and is a certified trainer for the Infraspection Institute.
“As a provider of training and unbiased certification in the Australian market i see my customers struggling to find unbiased information and genuine feedback to make decisions on equipment purchases. With limited experience it isdifficult to consider real world situations and equipment suitability. Understanding design and performance limitations only comes with years of real world experience. Hopefully, this site will provide them with the feedback and insite they need to make an informed decision” – Brenton Ward

Infrared Cameras or thermal imagers are now widely used for electrical and mechanical predictive maintenance, building diagnostics, forensics, research and development and many process control applications. Traditionally, thermal imaging systems have been very expensive. Just 10 years ago it would not have been uncommon for a system to cost over $100,000, however now prices start at just a few thousand dollars.
Recently the market has changed dramatically seeing high resolution infrared cameras drop by 50% or more (helped also by the strong Aussie dollar). Consequently most contractors can now afford a high resolution cameras (320×240 detectors or higher). In a market that has been flooded by low resolution detectors (160×120 or less) this has several implications. Firstly new purchasers of high resolution thermal imagers are now presenting high quality images to customers. Aesthetically, this is very pleasing to the human eye and no doubt wins great favour with end users. This makes it much more difficult for existing thermographers to provide a comparable report with their older, more expensive low resolution thermal cameras. As the market embraces high resolution thermal imagers, this will become more difficult for older thermal imaging systems to compete. Secondly, and beyond the aesthetic component, we have a significant increase in measurement accuracy due to smaller spots sizes due to the higher resolution. We now regularly hear from customers who have traditionally used lower resolution infrared cameras reports that they now measure significantly higher temperatures with their new high resolution infrared camera.
Higher resolution thermal imagers are always required where we need to measure small targets, distant targets or a combination of the two. Generally, the higher the resolution thermal the better the distance to spot measurement ratio. To put this into perspective, most 160×120 sized resolution thermal imagers will have a distance to spot ratio of approx 50:1, 100:1, 150:1 while high resolution thermal imgagers can have distant to spot ratios of 300:1, 400:1, 500:1 or higher. A thermal infrared camera with a distance to spot ratio of 100:1 can measure a 1cm target from a distance of 100 cm (1 meter). This ratio can be applied to any measurement.
