Using infrared sensors, the fingerprint acquisition system, cameras and LED digital tube, such as device design Infrared thermal fingerprint visualization entrance guard system.It uses the infrared thermal device to feel light and temperature ’s change. The sensor send the real-time ray signal to control circuit, which will lock LED human body induction switch according to the signal value.The control signal can be output when the human body go through the device with using a series of circuit processing,which can open or close automatically camera device in order to achieve visual purposes.The system has very big development space and practical value because of its the advantages of settings and simple operation, functional excellence.
