A common misconception about IR security cameras is that they somehow send out infrared scanning waves. Thermographic cameras work on essentially the same principle as traditional photographic cameras. This means that IR security cameras are every bit as flexible as regular CCTV surveillance cameras. Generally, they’re used to extend the range of surveillance equipment in low light areas. There are countless models available, and each of these is best suited for use in a particular type of installation. That being said, they still use a type of photography, so IR security cameras are just as safe to use as any other type of surveillance camera.
