Description
Technical field
The utility model relates to the infrared imaging field, specifically is to have warning function infrared network video camera.
Background technology
Infrared ray is a kind of electromagnetic wave, and its position in the electromagnetic wave continuous frequency spectrum is the zone that is between radio wave and the visible light.Infrared radiation is a kind of electromagenetic wave radiation the most widely that nature exists, it is based on any object all can produce molecule and the random motion of atom of self under conventional environment, do not stop eradiation and go out the thermal infrared energy, the motion of molecule and atom is more violent, the energy of radiation is bigger, otherwise the energy of radiation is littler.The object of temperature more than absolute zero all can give off infrared ray because of the molecular motion of self.
Thermal infrared imager is that the infrared energy distribution pattern that utilizes Infrared Detectors and optical imagery object lens to accept measured target is reflected on the light-sensitive element of Infrared Detectors, thereby the acquisition Infrared Thermogram, this thermography is corresponding with the heat distribution field of body surface.Generally thermal infrared imager is exactly to change the invisible infrared energy that object sends into visible heat picture.The top different colours of heat picture represents the different temperatures of testee.
At present and since infrared video camera have the misty rain of overcoming ability strong, to temperature characteristics such as comparatively sensitivity and smog penetration power be strong, therefore obtained in the forest fire protection field in recent years greatly using.But general infrared video camera can only be realized transmission of video signals at present, lacks necessary alarm, and especially when some dangerous situations occurring, reporting to the police just seems particularly important.
