Depending on what temperature you need or expect to detect with a CCTV with thermal imaging, you will choose a professional or a conventional one. Professional models are more expensive, obviously, and there's no point investing in them if you don't anticipate needing to scan extended temperature ranges. A conventional model, on the other hand, will be cheaper and allow temperature recognition in a much narrower range, usually between -20 degrees Celsius and 50 degrees Celsius. So please choose according to your actual needs because it would be sad to invest in a professional model and never have the opportunity to use it to its full potential.
