If you work in the security industry, the uses of a thermal image camera are well known. But thermal image cameras, meaning night vision cameras, are used in a multitude of businesses, and also, for hobbies. Any sophisticated security system makes use of thermal image cameras and/or videos, and security companies work directly with night vision equipment specialists. An ordinary roofer, plumber or electrician may need a night vision piece of equipment too, for nighttime emergency work, or for going into a deep, dark ceiling or a deep, dark basement. The food industry can use night vision equipment and in fact, all industries may need night vision equipment for one reason or another. And then there are the hunters or the safari guides, who need night vision cameras or night vision videos. This can be for work but it can also be for play and a hobby.
Difference between thermal image and night vision equipment
These two things are basically the same. Thermal cameras are cameras that are used at night. They work off heat and movement and can detect things up ahead of them, in the dark, through heat and motion. They do not need light to operate. A night vision video camera is set up near a waterhole, for example, but the animals are unaware of it. A security system has night vision cameras that can capture somebody breaking into a house, or similar, without the person being aware he or she is being photographed. And then a night vision camera can help a roofer see, a hunter target an animal, and an electrician to do his or her job properly!
Like a security company, get the night vision equipment you need from the suppliers directly. You can get a thermal image camera at a good price and of good quality.
