[ Huaqiang Security Network News ] Speaking of not laser infrared light, I don't know if you will use it? At the same time, in the process of using, we must also avoid some misunderstandings. This article will give you a detailed introduction to the three major misunderstandings of laser infrared lamps : 
Analysis of the three major misunderstandings of laser infrared lamps
1. Misunderstanding of supporting camera products
At present, many engineering companies get the laser infrared light. In the actual test process, the ordinary color-turning black camera is used to sense the infrared light of the laser infrared light. It is found that it is completely insensitive or very weak, and there is a feeling of being deceived. Otherwise, because the ordinary color-to-black camera adopts the filter technology, the infrared light except the 850 nm infrared light of the LED infrared lamp is filtered out, and the infrared light of the laser infrared lamp is the infrared wavelength of 808 nm, and the filter is used. Do not hesitate to filter out. Therefore, it is impossible to sense or the induction is weak.
Cameras that can be retrofitted with laser infrared lamps are almost always using dual-filter switching IRC technology, but the use of this technology is generally relatively expensive, so there are only a few internationally renowned brands. Cameras like SONY, Samsung, Panasonic, LG, etc. almost all series of products use this dual filter switching technology, and there are also some manufacturers in China such as Jingyang, Hongtianzhi, Xiangfei, Lerong, Topang, Siyat Some series of products use dual filter switching technology, and most manufacturers have begun to use the filter band of the modified filter to pass the 810nm laser infrared light, or directly find the filter manufacturer to order the 808nm laser infrared light. The filter is compatible with the laser infrared light at a lower cost to adapt to the night vision trend of the future infrared light toward the laser direction.
2, misunderstanding
People often understand the laser infrared light with the knowledge of LED infrared light. LED infrared light characteristics are not directional, the beam angle is large, and a plurality of LED lights can be gathered together to achieve near-interval omnidirectional illumination, but LEDs do not have directionality, so only a few tens of meters apart can be achieved. illumination.
With this understanding, I hope that the laser infrared light and the LED infrared light can achieve all-round illumination at 100 meters, 200 meters, 300 meters and 500 meters. In fact, there is no laser infrared technology available in the world. Interval omnidirectional illumination can only achieve a local range of illumination at medium to long intervals.
Of course, the laser technology continues to advance, and it is a matter of morning and evening to achieve a larger area of ​​illumination within 300 meters. The zoom laser infrared light NG250B recently launched by Dapu Company can realize the lighting needs of both far and near.
3. Misunderstanding of engineering installation
Most customers have the understanding of the installation of LED infrared lamps, and bundle the LED infrared lamps with the camera to achieve near-interval wide-angle illumination. Because of the close interval, if the LED infrared lamp is not bundled with the camera, it will produce obvious aperture phenomenon. Will produce bad results.
With this understanding of LED infrared light, to understand the laser infrared light, because the contact with the laser infrared light is not deep, imagine that the laser infrared light can achieve more than 100 meters of all-round illumination, of course, the laser infrared light and the camera bundle Do engineering installation together.
Some pragmatic technology companies are clearly familiar with the market demand. The COSCO interval laser infrared lamps have a certain range of illumination. The effect of binding the laser infrared lamps to the camera is not necessarily the best, and the engineering cost. The difference is reflected here.
In the realization of remote interval monitoring, if the design of the scheme is not ideal, it may not achieve good monitoring and the cost of the project will increase. This time, the engineering installation technical strength of large-scale engineering companies is reflected. How to install the laser infrared light and the camera separately in different directions according to the project site environment to achieve a more reasonable installation plan, has become a technical problem in front of the major engineering companies.
At the same time, this is also a technical difference that reflects the engineering installation of small equipment wholesalers of large engineering companies.

Clout Nails
Clout nails are a kind of large head Roofing Nails. Also known as shingle nails or felt nails. A clout is a relatively short, thick nail with a large, flat head used for attaching sheet material to wooden frames or sheet. A typical use is fixing roofing felt to the top of a shed. Clouts are also used in timber fence palings. They are usually made of galvanized mild steel, but copper clouts are also available.
