Attention when installing explosion-proof infrared camera

In the selection of explosion-proof infrared cameras and the installation and installation process, the key personnel should make a simple induction and analysis. Explosion-proof infrared camera installation position to avoid strong light (such as sunlight, lights, etc.), otherwise it will easily lead to excessive bright or light (not a fault), it will also affect the life of the CCD; In addition, infrared light has the same reflection as visible light , refraction and other characteristics, so in the absence of a good reflective environment around the target scene (such as buildings, walls, signs) should consider a certain distance margin; different media transmittance and reflectivity are different, so different protective glass, especially Glass with automatic defrosting coating will cause some attenuation of infrared light, and special attention must be paid to construction. Explosion-proof infrared cameras should be kept away from humid, dusty, extremely hot, cold, and strong electromagnetic radiation. Weather conditions such as rain, fog, and dust are all factors that restrict the distance from the infrared light. In addition, the differences in the reflectivity of the on-site environment and the monitoring target will also make the night vision effect very different. Therefore, it must be tested before installation. The camera is well tested.

Explosion-proof IR cameras and low-light-proof explosion-proof cameras can perform all-weather monitoring tasks in some places where flammable and explosive gases exist. Especially in the dark environment at night, ordinary explosion-proof surveillance cameras cannot work normally, while explosion-proof infrared cameras and low-light-proof explosion-proof cameras can perform normal monitoring work. It is precisely because they all have the characteristics of normal work in a very low light environment, making them a rival in the night vision explosion-proof monitoring market, but can the two really replace each other? What kind of connection and difference do they have?

The low-light-proof explosion-proof camera does not rely on the auxiliary light source. With its advantages of self-sensitivity and digital signal processing, it can be monitored in an extremely low-light environment. The quality selection of low-lightness explosion-proof camera devices is higher than that of ordinary explosion-proof cameras, and some unique technologies are also applied to further enhance the low-illuminance performance. Therefore, the cost of low-lightness explosion-proof cameras is high. Explosion-proof infrared cameras use LED lights for auxiliary lighting, so that they have sufficient illumination to complete the monitoring, so its cost is relatively low. Under night vision surveillance sites without special requirements, explosion-proof infrared cameras with relatively low cost are generally used. However, because the explosion-proof infrared camera requires the use of infrared light for auxiliary lighting, in some occasions it is not suitable to use explosion-proof infrared cameras for monitoring, and only use low-intensity explosion-proof cameras for monitoring.

Explosion-proof manufacturers continue to increase, and more and more explosion-proof infrared camera brands. However, the conditions for factory testing, technology, and testing instruments and equipment of related products are not all the same. Users should choose more explosion-proof infrared cameras for comparison. Explosion-proof infrared cameras on the market are mostly used in the two infrared bands of 850nm and 940nm, and the infrared wavelength band of 850nm is more stable; in addition, users are advised to choose explosion-proof infrared cameras with electronic control switching devices, whose fuzzy logic capability can effectively control ICR- The working status of the CUT filter can make the infrared light compensation effect more stable. Some manufacturers of infrared explosion-proof infrared cameras have no irradiation distance parameters, only the number of power, which is a very vague concept, because the power consumption is converted into infrared light energy, it also includes power heat loss, circuit heat loss, light source heat loss , filter glass infrared light efficiency and so on. That is, the same power of the infrared projection lamp, the irradiation distance may be very different. The user should consult the manufacturer carefully for the relevant parameters when selecting.

The low illumination explosion-proof camera and the explosion-proof infrared camera are complementary products. The low illumination explosion-proof camera has the advantages of high cost, high quality, and no need of auxiliary light to make up for the blank of the explosion-proof infrared camera in certain places for night vision monitoring, but it must be noted when selecting. Manufacturer's qualifications, while the explosion-proof infrared camera because of the low cost of the advantages of occupying the special explosion-proof night vision surveillance market.
