A good example of this would be the infrared camera. Unlike our own eyes, infrared security cameras can 'see' using light in the infrared wavelength spectrum. This means that infrared cameras are very useful in security monitoring situations. Areas that we would say are in total darkness (a Lux 0.0 condition) are visible through an infrared security camera. Businesses and industries, banks and warehouses have been monitored with infrared security cameras for many years. They have proven to be an effective crime-deterrent. But increasingly, they have been used in the home as well as in industrial and business environments. People with especially large, darkened back yards, for example, will use infrared security cameras to monitor their property for intruders - whether they be human or animal (stray deer, dogs, rodents, wolves). The really nifty thing about infrared security cameras is that they can be located in the darkest of environments, yet still provide a camera image. And this is certainly bad news for the professional thief, who typically seeks out darkened rooms and homes for a break-in. They assume that the darkness will make it impossible for them to be detected. But infrared security cameras will catch them every time! Make sure that any infrared security camera that you purchase has an 'auto-scan' function. When a camera is set to auto-scan, it will move back-and-forth, covering the same area repeatedly. So you can set up several of these cameras to monitor a specific area continuously. In this way long and large areas, such as hallways, driveways and entrance lobbies can be monitored effectively. Unlike regular security cameras, which need the light of the sun - or a light bulb - to provide an image, infrared security cameras generate their own light. They do this in one of 2 ways: They can either shine a beam of light out into the area from the camera unit itself, or they can rely on an external infrared emitter, which when turned on shines the (invisible to us) infrared light into the environment, so that an image can be captured. Please do NOT confuse infrared security cameras with so-called 'low light' cameras. Low light cameras are capable of capturing images in very low levels of ordinary light - during the early morning hours, or at dusk, for example. Also keep in mind that infrared security cameras work best in monitoring small areas rather than really big lobbies and parking lots. Some models are dual-function cameras: they combine infrared technology with a 'regular' security camera unit - the infrared capability will switch on when the other technology cannot function.
