Surveillance and CCTV closed circuittelevision have become a booming industry over the last few years. Cameras are being installed everywhere; locations such as trafficsignals, parking lots, corporate and small businesses, supermarkets,industrial plants, hospitals, airports, all the way to the plains ofthe Serengeti for viewing PTC Heaters Suppliers wildlife via a wireless IP camera.
The simple fact isthat there is probably some form of CCTV in every public place thatwe travel to and from. At the moment, CCTV is mainly used forsecurity surveillance. Most standard security cameras have whatsknown as night vision; which means when darkness falls, the camerashave a built in infrared illuminator that uses infrared light insteadof the regular lighting spectrum in order to produce better images incomplete darkness or low light conditions. This type of night visioncamera only records in black and white, but some cameras will recordcolor during the day. The main drawback to this type of infraredilluminator camera, is that the viewing distance of the camera islimited to the range of the infrared light emitters project. Donot confuse an infrared camera with a day/night camera. Day/nightcameras can record in low light, but not in zero light and do not useinfrared lighting that actually sees into the infrared spectrum.
True infraredcameras do not use IR illuminatorsinstead they use a microbolometer; this is a special type of sensorthe camera uses to see light from a different region of theelectromagnetic spectrum than we normally use to see. This type ofcamera is not dependant on any light source to see. Now with severalnew advances in infrared technology; we are discovering new fields ofuse for true full spectrum infrared cameras integrated with CCTVunits. Since all warm-blooded animals exude heat; Infrared cameraswork great for security systems. Even at thezero light level, an infrared camera will still see the normally nonvisible light from your heat signature.
Obviously theability to see at night without any light necessary is an excellentboost to any security system. But what other benefits can infraredcameras offer with surveillance systems? CCTV is now being used withinfrared camera systems to monitor industrial equipment or anythingtemperature relevant, this can be used in a multitude ofapplications. Many industrial plants have been using this method tomonitor temperature related situations; such as the temperature of apipe or the liquid flowing through that pipe, analyzing simple orcomplex machinery, circuitry, or wiring to view what component isrunning above or below operation tolerances for the devicesoperational runtime.
In short, theInfrared CCTV cameras can be applied in many different modes. Remoteor local security CCTV can operate in low or nonexistent lightlevels, especially at night. Infrared CCTV also has otherapplications such as, constant operational runtime monitoring,diagnosing, troubleshooting, and analysis.
