These programs are used to code and decode data or signals from one format to another so that the end devices are able to interpret and play the signals. Media like audiotapes and VHS/Betamax tapes use analog signals to store the files while CODECs are meant to store digital files. Thu, 05 Jul 2007 articles/codec-devices.html articles/infrared-sensors.html Infrared (IR) sensors are used in night vision cameras and goggles to detect heat emitted by objects. Since ambient light is absent, radiations emitted by the object are picked up by the sensors and used to form an image of the object. These devices can detect the presence of an intruder and are very important in guarding sensitive infrastructure. They are also used for non-contact temperature measurement.
