This diameter of this series glass bead is two or three times bigger than regular beads. The surface part beyond paints is higher than regular beads; hence the reflectivity of road marking has been increased, especially in rainy, foggy areas.
The glass bead can be produced based on the standard of countries or areas, such as EN1423/1424, AASHTO M247, BS6088, JIS R3301 and KS L2521 etc.

Infrared camera installation considerations
First, installation precautions
1. Debug infrared light must be performed at night. The infrared beam illumination position is adjusted at night through an imaging device such as a monitor. And can effectively adjust the lens aperture settings.
2. The infrared light can't directly face the camera. The infrared light seen by the camera is the same as the sunlight that humans see.
3. The infrared lamp is not necessarily installed in the same position as the camera. If the camera is far away from the illuminated object, you may consider installing the infrared lamp between the two. The best way to install in the same location is to install the infrared lamp and the camera in an overlapping manner.
4. The installation height of the infrared lamp should not exceed 4 meters, too high will affect the reflectivity of light. The angle should be from the top down angle of 20 degrees, and the elevation angle is too large to reflect.
5. The working indicator of the infrared lamp must be guaranteed (see the product specification for details). For example, the power of the infrared lamp must be higher than the working power of the infrared lamp itself.
6. The user must first read the instruction manual carefully when using the infrared light, especially the precautions to ensure personal safety. Check whether the supporting aspects mentioned in the previous section meet the requirements. Whether the influencing factors that should be taken into consideration should be taken into consideration, if not meet the requirements, the equipment used can be adjusted in time.
The diameter is 850-1400mm (20-14mesh) with ≥80% of roundness. The special coating on the surface of glass bead can improve the adhesion between paint and glass beads, thus the longevity can be increased.
Infrared camera installation
At present, China's security industry is moving from the start-up period to the development period, the industrial chain has basically been formed, and the management chain is also being established. As the market demand continues to increase, the security industry will usher in a broader space for development. Infrared monitoring is an important application in the field of security monitoring and is rapidly developing under the tide of the Internet of Things.
