Tempered Glass is often used in applications where using standard glass could pose a potential danger. Tempered glass is stronger than standard glass and does not shatter into large shards when broken. This is important, because it can greatly minimize potential danger in the case of a break. Manufactured through a process of extreme heating and rapid cooling, tempered glass is much harder than normal glass.
Tempered or toughened glass is a type of safety glass processed by controlled thermal to increase its strength compared with normal glass. Tempering puts the outer surfaces into compression and the interior into tension. Such stresses cause the glass, when broken, to crumble into small granular chunks instead of splintering into jagged shards as plate glass (a.k.a. annealed glass) does. The granular chunks are less likely to cause injury.
Clear tempered glass is most widely used windows, doors, partitions, shower room, table top, glass wall and so on. It is substrate, it can be processed into printed tempered glass, back painted tempered glass, frosted tempered glass and so on.

Panoramic camera application advantages <br> <br> currently panoramic cameras are mainly used in outdoor vision places, such as road traffic, open-air plaza, residential buildings, ports, etc., some places even up to monitor the width of meters above, see the At the same time when the panoramic image is dispatched, it is impossible and incapable to look at the details such as face and vehicle license. These occasions only need to install a fisheye camera at the high point to meet the panoramic monitoring in a place. Compared with traditional surveillance cameras, the advantages of panoramic cameras include:
Ultra-wide viewing angle monitor <br> <br> a fisheye lens are collected in a 360-degree panorama, it can replace traditional multi-camera support: users need only a special fish-eye lens will be able to directly view the entire space around the image once Take a panoramic view and completely eliminate the dead ends.
Reduce costs <br> <br> panoramic camera of this 360-degree panoramic view real-time monitoring capabilities, making it unnecessary to cover the entire area and installation of monitoring multiple cameras, thus saving the camera hardware investment. The number of surveillance camera channels is greatly reduced, which can save the cost of supporting equipment, such as lenses, protective covers, wiring, power supply, video, display and other related accessories and equipment. It can also reduce the difficulty of construction wiring, save installation time, labor costs and follow-up maintenance costs .
Virtual PTZ PTZ technology <br> <br> virtual technology, a monitor image can be enlarged or moved within the field of view region, change direction observed when the other image areas, does not emit any noise, hidden and difficult to detect. Because there are no mechanical moving parts and no mechanized operation is required at any time, the panoramic camera will not suffer any wear and the product will be robust and long-life. The image distortion correction of the panoramic view can be performed on a plurality of image areas. Thus, unlike the mechanical PTZ camera, the panoramic camera can simultaneously observe and record a plurality of different areas.
Panoramic camera panoramic camera installation points <br> <br> very high in integrated circuit technology, using a panoramic camera, you must first understand the panoramic surveillance cameras, the following small series will introduce you to the installation point panoramic camera.
1. The ceiling installation should be centered in the monitoring space. Because the panoramic camera can restore the image after stretching to more than 2-4 plane images. If the camera installation position is not centered, the restored image will have edge image asymmetry, and there will be focus monitoring area offset. Happening.
2. Avoid ceiling fixtures. Panoramic cameras should avoid close to ceiling fixtures or chandeliers when ceiling mounted. The panoramic camera has strong light in the foreground, and it easily diffuses the light and light fields into a single curved image. Although the panoramic camera has wide dynamic (WDR) and strong light suppression (BLC) functions, it is often under wide dynamic and backlight motions. The brightness of the edges of the image will be less than the effect of no bright light; and the starting transformer frequency of the lamp is often the culprit of the interference of the camera image signal, and this situation should be avoided as much as possible.
3. Avoiding the indicator light When installing the ceiling camera, the panoramic camera should avoid the front of the emergency exit lighting fixture and the front or the top of the red indicator light of the fire box. The panoramic camera has these lights in the foreground, and it is easy to spread the light field. For a group of music images, the clear effect of image monitoring is affected.
4. Avoid air conditioning vents Panoramic cameras should not be installed on the edge or in front of the air conditioning vents when installed. In past experience, everything was working as usual after installing a panoramic camera in the winter, but in the summer, the group of panoramic cameras was after 10 a.m. The camera lens will produce a mist-like condition, which is caused by the front of the air conditioner.
5. Avoid the entrance and exit electric door The panoramic camera installation position should be avoided above the entrance door. If the camera is installed at the top of the electric door or in front of the door, the camera window will produce condensation drops due to the temperature difference, which will affect the video monitoring effect. .
6. PoE-powered panoramic cameras should use PoE power supply as much as possible, because the aesthetic treatment of a single cable is simple and easy. If a DC power supply is used, the power supply and the line must be preset before installation. Will damage the decoration, and in the follow-up maintenance, if the power supply failure, but also damage the decor, which is quite unfavorable to the maintenance costs.
7. Use expansion screws to fix the panoramic camera. When installing on the ceiling of the fiber, it must be fixed with expansion screws. It cannot be fixed with ordinary screws. In order to isolate the electromagnetic interference in the ceiling, the panoramic camera has a considerable weight. If it is fixed on the ceiling, it is not fixed by expansion screws, and there is no pre-installed safety cable. After the project is completed for a period of time, the camera will fall. .
A panoramic camera is a camera that can perform global image monitoring in a surveillance location. It can be called a panoramic camera, which means that a fisheye lens or a multi-shot camera with multiple cameras and a multi-channel video fusion chip can be used as a panoramic camera.
