As a video image signal acquisition device, a road monitoring camera is specifically used to monitor target objects such as vehicles, drivers, pedestrians, and markers in a moving road. It requires all-weather continuous operation and can be captured in real time and clearly. The target object's feature information. The development and urgent needs of the domestic intelligent transportation industry have further deepened the application of road surveillance cameras in the transportation sector and continue to play a significant role. Because the use environment of the road surveillance camera is more complex, harsh, and unpredictable, its design, production, and manufacturing standards are more stringent than other common surveillance cameras. It must ensure effective use in a variety of complex road environments, and the quality of captured video images is clearer and more accurate. The performance requirements of road surveillance cameras are also increasing, and the product form is also more specialized and serialized. In recent years, new high-tech products such as high-definition cameras, infrared cameras, automatic tracking cameras, network cameras, high-light suppression cameras, and wide dynamic cameras have been introduced in accordance with various application requirements.
1, high-definition monitoring. As the city's "watcher", it must have a pair of bright eyes to see more "clean" and more "far". High-definition surveillance is the first choice and must-have product for road surveillance cameras. As the demand continues to increase, the image resolution also increases. If the main road for urban traffic, the camera image reaches 540 lines or even 600 lines. How to look farther, we must use a zoom camera, optical zoom 18 times, 25 times, etc., can meet the needs of long-distance monitoring.
2, SNR and color reproduction. Road surveillance cameras are all-weather surveillance and have strict product requirements. Especially in extreme weather or poor weather conditions, surveillance cameras with high signal-to-noise ratio can meet the monitoring standards. If the signal-to-noise ratio is 50 db, the image has a small amount of noise, but the image quality is good; if it is 60 db, the image quality is good and no noise occurs. The signal-to-noise ratio of general road surveillance cameras must be greater than 50db. Considering the quality of a camera also depends on its color reproduction - white balance, so as to ensure the image output.
3, with the ability to deal with extreme weather. Road surveillance cameras are located outdoors and must have hard skills when dealing with extreme weather. In current road surveillance cameras, there are more and more cameras with wide dynamic and infrared night vision effects. Not only can they guarantee surveillance capture in low light conditions, but they can't escape the "electronic*" method at night. If you live in a city like "Fog", you may be able to see one of the reference factors for the night vision of the camera's fog.
4, excellent shell and waterproof, explosion-proof function. The road all-weather surveillance camera must have a strong metal shell, can withstand years of wind and rain. The product's waterproof, explosion-proof, and anti-fog functions should also be prominent. In addition to the above-mentioned special features, these manufacturers are required to be more skilled in the process. The integrated camera is a good choice.

SSS: Spunbond non-woven fabric + spunbond non-woven fabric + spunbond non-woven fabric = 3 layers of fiber web hot rolled; S non-woven fabrics, SS non-woven fabrics, SSS non-woven fabrics can be produced, according to non-woven fabrics Cloth performance can be used for: surgical gowns, protective clothing, disinfection wraps, masks, diapers, civilian wipes, wipes, soft towel rolls, beauty products, sanitary napkins, sanitary pads and disposable sanitary cloths Cloths, tablecloths, bed sheets, bedspreads; clothing linings, fusible linings, wadding, shaped cotton, various synthetic leather base fabrics, industrial filter materials, insulating materials, cement packaging bags, geotextiles, covered cloths, crop protection cloths, seedling cloths , Irrigation cloth, thermal insulation curtain, other space cotton, thermal insulation materials, linoleum, cigarette filters, tea bags, etc. Mainly used in disposable hygiene products industry, medical health industry, beauty care and other industries.In terms of environmental protection, the raw material of most of the non-woven fabrics currently used is polypropylene, while the raw material of plastic bags is polyethylene. Although the names of the two substances are similar, their chemical structures are far apart. The chemical molecular structure of polyethylene is very stable and extremely difficult to degrade, so it takes 300 years for plastic bags to be decomposed; while the chemical structure of polypropylene is not strong, the molecular chain can easily be broken, which can be effectively degraded , And enter the next environmental cycle in a non-toxic form, a non-woven shopping bag can be completely decomposed within 90 days. Moreover, the non-woven shopping bag can be reused more than 10 times, and the pollution degree to the environment after being discarded is only 10% of that of the plastic bag.
