Today, I will introduce the seven advantages of high resolution thermal imaging camera monitoring, mainly from seven aspects to explain in detail. With the continuous development of the security industry, optoelectronic information, microelectronics, network communications, digital video, multimedia technology and sensor technology are more integrated into the field of video surveillance. Among them, thermal imaging technology has been widely used in key security fields such as banks, airports, oil fields, prisons, military facilities, ports, waterways, and public security law enforcement with its advantages of all-weather ability and high sensitivity.
Ⅰ. Classification of high resolution thermal imaging camera
When it comes to thermal imaging technology, we have to mention a high resolution thermal imaging camera, which is also called a thermal imaging camera. However, don't be confused. Thermal imaging cameras are generally divided into two categories, one is used to measure temperature, and the other is used for security monitoring. The latter is also called thermal imaging camera. Due to the limitations of price and maturity of use, high resolution thermal imaging camera has not achieved rapid development.
Ⅱ. Advantages of high resolution thermal imaging camera
In recent years, as people's monitoring requirements continue to increase, there are more and more monitoring requirements for all-weather and harsh environments. Although there are many types of cameras on the market, such as infrared cameras, low-light cameras, strong light suppression cameras, and Wide-Dynamic cameras, etc., are used to meet people's monitoring needs in low-light or even completely dark environments, but the monitoring effect is not satisfactory.
In this context, thermal imaging cameras have become popular, and they have gained the favor of the market for their long range of action, strong penetrating ability, and ability to identify hidden targets. So, what are the advantages of high resolution thermal imaging camera compared with technologies such as low illumination, laser lighting and infrared lamps? Let's analyze it below:
1. Long range
General infrared light products have an imaging distance of less than 100 meters. The high resolution thermal imaging camera images the infrared rays radiated by the object without being restricted by ambient light and illumination light. Generally, a telephoto thermal imaging camera can observe people over 3 kilometers and vehicles over 6 kilometers.
2. Strong concealment
The high resolution thermal imaging camera receives signals completely passively and does not actively transmit detection signals, so it is not easy to be detected by counter-reconnaissance means.
3. Strong penetrating ability
Infrared thermal radiation has a stronger ability to penetrate fog, haze, rain, and snow than visible light, so the imaging effect of high resolution thermal imaging camera under bad weather conditions is almost unaffected. In particular, the long-wave infrared thermal imaging camera that acts on 8-14um has a stronger ability to penetrate fog.
4. Ability to work around the clock, resist strong light interference
High resolution thermal imaging camera imaging does not rely on illuminating light and ambient light, but relies on the radiation of the target and the background to produce scene images. Therefore, the thermal imaging camera can work 24 hours a day, and it will not be exposed to visible light as other night vision equipment. interference. The low-light camera cannot image without ambient light.
5. Ability to identify hidden targets
Ordinary camouflage is based on anti-visible light observation. The crimes committed by criminals are usually hidden in the grass and woods. Due to the harsh outdoor environment and human visual illusions, they are prone to misjudgment. The high resolution thermal imaging camera can detect hidden thermal targets through camouflage and grass and leaves. The temperature and infrared radiation of the human body and vehicles are generally much greater than the temperature and infrared radiation of the vegetation, so it is not easy to camouflage, and it is not easy to make mistakes.
6. Fire protection monitoring
Normal fires are caused by unobvious hidden fires. Using existing common methods, it is difficult to find signs of such hidden fires. Because the high resolution thermal imaging camera is a device that reflects the surface temperature of an object, it uses an infrared thermal imaging camera to find a fire point through the smoke, so that it can be known and prevented and extinguished early.
7. Low power consumption and long life
Because laser lighting or infrared lamps require active lighting, the power consumption of the whole machine is relatively large. In some special power supply occasions, a low-power infrared thermal imaging system must be used. Since the heat dissipation problem of active systems such as infrared lamps is not easy to solve, the life of ordinary infrared lamps is only 1,000 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.
