Panoramic surveillance camera installation
The installation and construction conditions of the panoramic network cameras are similar to those of conventional surveillance cameras. Due to the requirements of ceiling mounting and wall mounting, the following points need to be taken into consideration when cooperating with the environment:
1. Avoid ceiling lighting The panoramic network camera should avoid close to ceiling lamps or chandeliers when ceiling installation. 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 irradiation; 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.
2. The ceiling installation should be centered in the monitoring space. Because the panoramic surveillance camera can restore the image after the image is stretched 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. Case.
3. Avoiding air-conditioning vents Panoramic network cameras should be installed without installing them on the edge or in front of air-conditioning vents. In past experience, everything was working as usual after installing a panoramic camera in winter, but in the summer, the group of panoramic cameras was at 10:00 am After that, the lens of the camera will have a misty appearance, which is caused by the front of the air conditioner.
4. Avoiding the indicator lamp 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 of light. For a group of music images, it affects the clear effect of image monitoring.
5. 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.
6. Use expansion screws to fix the panoramic camera. When installing on the ceiling of the fiber, it must be fixed with expansion screws. Do not use it 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. .
7. Avoid the entrance and exit electric gates. The panoramic network camera installation position should be avoided above the entrance door. If the camera is installed above the electric door or in front of the door, it will cause the camera window to condense due to the temperature difference, affecting the video monitoring. effect.
The above 7 points are some important considerations for the installation of the panoramic network camera. 
Efficiency factor <br> <br> panoramic camera panoramic camera due to the network is not the same imaging principle with ordinary surveillance cameras, image correction reduction is an issue that needs to be considered. It is generally recommended that front-end cameras build their own software systems, which can ease the pressure of network transmission and back-end storage. Surveillance cameras have a characteristic. Generally, wide-angle cameras are relatively close to the surveillance distance. This is also true for a panoramic camera such as a fish-eye surveillance camera. Although the field of vision is wide but the line-of-sight is very short, it is necessary to consider both the visual field and the distance. Consider the skills and capabilities of our construction personnel.
Therefore, panoramic surveillance cameras have more factors in installation than traditional surveillance cameras, and mastering the installation method of panoramic cameras can only give full play to its performance.
