Today, the challenge to CCTV professionals is to make sure that video footage is effective on a 24/7 basis, 365 days a year. Securing an area during the daytime is one thing. But what can be detected if CCTV cameras are blinded by the sun? And in weather conditions like fog, rain and snow? And what happens during the night, in total darkness?

How Far Can You Measure? Considering Spot Size Ratio is Key... If you recently bought a thermal camera, you might be wondering how far you can measure with it. Or maybe you’re interested in purchasing one, but you aren’t sure which one will both accurately measure your target and fit within your budget. The answer to “how far can you measure?” depends on factors such as resolution, Instantaneous Field of View (IFOV), lenses, the size of the object, and more. You can compare it to a visual exam at the doctor’s office. When you look at the eye chart from...

A thermal imaging camera records the intensity of radiation in the infrared part ofthe electromagnetic spectrum and converts it to a visible image. What is infrared? The visible light spectrum. All other forms of electromagnetic radiation, such asinfrared, are invisible to the human eye.The existence of infrared was discovered in 1800 by astronomer Sir FrederickWilliam Herschel. Curious to the thermal difference between different lightcolors, he directed sunlight through a glass prism to create a spectrum and thenmeasured the temperature of each color. He found that the temperatures of thecolors increased from the violet to the red part of the spectrum.After...

We’re s’not kidding when we say this is a whale of a story! The Massachusetts-based Ocean Alliance has been using a unique and innovative thermal imaging-equipped research drone with a a series of petri dishes that collect whale blow, or, snot. Cleverly named the ‘SnotBot,’this modified DJI Inspire drone is equipped with a FLIR Vue Pro thermal imaging camera and is flown into the blow from whales to collect samples. The whale blow collected by SnotBot contains DNA, micro biomes, pregnancy hormones, and stress hormones and helps researchers to better understand these massive mammals. Interestingly, with the Vue Pro on...

George Powell, Director of Wildlife Conservation at World Wildlife Fund shares how they are using drones equipped with thermal to aid the organization's research and conservation efforts of large and endangered species in Africa. Q: Tell us about your project?A: We are testing the limits of small drones as a tool for managing national parks and other protected areas while working to expand those limits through strategic R&D. We have focused mostly in African savanna, where populations of large animals, including elephants, rhinos, and lions, are experiencing such severe rates of decline that they will likely disappear if these trends...
