Analysis of Infrared Light Wavelength and CCD Photosensitive Capability

[ Pacific Security Network News ]
As we all know, the infrared light panels used in the security monitoring industry mostly use infrared light with a spectral frequency range of 850 nm to 940 nm. The infrared light panels sold on the market are mostly 850 nm wavelength light panels. For the wavelength range of the infrared lamp, we found through testing and research that the same CCD board machine has different sensing powers for different wavelengths of infrared light. Below we take 850nm and 940nm as examples to analyze the infrared light wavelength and CCD board. Photographic ability.
Friends who know the characteristics of the spectrum know that the shorter the wavelength of a particular light, the more energy it carries. Take the ultraviolet light we are familiar with. Its wavelength is relatively short compared to visible light. Therefore, it is very penetrating and carries a lot of energy. It can break the cellular structure of the human body, so people must prevent it. Ultraviolet light.

The infrared wavelength is the same as the ultraviolet light. When the wavelength is shorter, the light energy is larger and the penetration is stronger. Through this principle, we found that 850nm infrared light can be more perceived by the CCD board. Later, people found that the infrared light penetration ability of 850nm wavelength is more than 5 times stronger than the infrared light of 940nm wavelength.

Therefore, many surveillance cameras use 850nm wavelength infrared light as the camera night vision light source. In addition to strong penetrability, more importantly, it is more sensitive to the camera CCD board machine.

Welded Wire Mesh Rolls

Welded WIRE MESH Rolls: Welded wire mesh rolls are flexible rolls of wire mesh that are made by welding steel wires together at their intersections. They come in various widths and lengths and are commonly used for a wide range of applications, including fencing, animal enclosures, garden protection, and reinforcement in concrete. Welded wire mesh rolls offer strength, durability, and ease of installation, making them a popular choice for both residential and commercial projects.
Hot-Dip Galvanized Welded Wire Mesh: Hot-dip galvanized welded wire mesh is a type of welded wire mesh that has undergone a galvanizing process. In this process, the mesh is immersed in a bath of molten zinc, which forms a protective coating on the surface of the wires. The zinc coating provides excellent corrosion resistance, making hot-dip galvanized welded wire mesh suitable for outdoor applications where exposure to moisture and harsh environments is expected. It is commonly used for fencing, construction, and industrial purposes.
Hot-Dip Zinc Welded Wire Mesh: Hot-dip zinc welded wire mesh is another term used for hot-dip galvanized welded wire mesh. It refers to the same type of mesh that has been galvanized through the hot-dip process, resulting in a protective zinc coating. The zinc coating helps prevent rust and corrosion, ensuring the long-term durability of the wire mesh. Hot-dip zinc welded wire mesh is widely used for various applications, including fencing, animal enclosures, and reinforcement in concrete structures.
Hot Dip Galvanized Iron Wire Mesh: Hot-dip galvanized iron wire mesh is a type of wire mesh that is made from galvanized iron wires and has undergone the hot-dip galvanizing process. The iron wires are immersed in molten zinc, resulting in a protective zinc coating on the surface. This coating provides excellent corrosion resistance, making hot-dip galvanized iron wire mesh suitable for outdoor applications, especially in environments where rust and corrosion are concerns. It is commonly used for fencing, agriculture, and industrial purposes.
These different types of wire mesh, including welded wire mesh rolls, hot-dip galvanized welded wire mesh, hot-dip zinc welded wire mesh, and hot-dip galvanized iron wire mesh, offer varying levels of corrosion resistance and durability. The specific choice depends on the intended application, environmental factors, and the level of protection required.
