Infrared cameras allow you to conduct inspections from a safe distance. That means you may not have to shut down the operation or suit up in full personal protective equipment. They save production time as well as help prevent exposure to hazardous environments. However, for some applications, you need to capture images of objects that would be very difficult to get close enough to without entering a danger zone, climbing a ladder or maybe even using a lift or a helicopter. You are going to need a lens add-on for your camera. High-quality telephoto and macros lenses are often called “smart lenses”, as they require no calibration for use with a specific camera. They can also be used interchangeably with other compatible infrared cameras.
