Analysis of the Seven Advantages of Infrared Thermal Imager

[ Huaqiang Security Network News ] Infrared cameras have an absolute advantage:
Infrared camera
1. The distance of action is far. General infrared light products have an imaging distance of less than 100 meters. The thermal imager images the infrared rays radiated by the object, and is not limited by the ambient light and the illumination light. Generally, the telephoto thermal imager can observe more than 3 kilometers of people and vehicles of more than 6 kilometers.
2, strong concealment. It completely receives the signal passively and does not actively transmit the detection signal, so it is not easy to be discovered by anti-reconnaissance means.
3, strong penetration. Infrared heat radiation has stronger ability to penetrate fog, haze, rain and snow than visible light, so the imaging effect of infrared thermal imaging system under severe weather conditions is almost unaffected. In particular, the long-wave infrared thermal imager that acts on 8-14um has a stronger ability to penetrate fog.
4, all-weather work ability, anti-glare interference. Infrared thermal imager imaging does not rely on illumination and ambient light, but on the target and background radiation to produce a scene image, so the infrared thermal imaging system can work 24 hours a day, and will not be exposed to visible light like other night vision devices. interference. Low-light cameras cannot be imaged without ambient light.
5, can identify hidden targets. Ordinary camouflage is based on anti-visible observation. The crimes committed by ordinary criminals are usually hidden in the grass and woods. Due to the harshness of the wild environment and the visual illusion of people, it is easy to make false judgments. Infrared thermal imaging can detect hidden thermal targets through camouflage and grass leaves. The temperature and infrared radiation of human body and vehicle are generally much larger than the temperature of the vegetation and infrared radiation, so it is not easy to disguise and it is not easy to make false judgments.
6, fire monitoring. The general fire is caused by an inconspicuous igneous fire. With the existing common methods, it is difficult to find such hidden fire signs. Since the infrared thermal imager is a device that reflects the surface temperature of the object and is imaged, the infrared thermal imager is used to find the fire point through the smoke, so that early prevention and early suppression can be achieved.
7, low power consumption and long life. Laser illumination or infrared lamps require active illumination, and the power consumption of the whole machine is relatively large. In some special power supply situations, a low-power infrared camera system must be used. Since the heat dissipation problem of active systems such as infrared lamps is not well solved, the life of ordinary infrared lamps is only 1000 hours, and the life of laser illumination is about 10,000 hours, but the life of uncooled infrared thermal imagers can reach 45,000 hours.
