Hemispherical camera, as the name suggests, is a hemispherical shape, which is only named for the shape. Hemispherical camera is suitable for workplaces and places with high decoration level because of its small volume and beautiful appearance. At that time, the generation of hemispherical camera pictures was mainly from CCD hemispherical camera. CCD is the abbreviation of charge coupled device. It can change light into charge, store and transfer the charge, and also take out the stored charge to change the voltage. Therefore, it is an ideal camera element. The CCD camera composed of it has small volume, light weight and is not affected by magnetic field It has the characteristics of anti shock and impact and is widely used.

Composition of hemispherical camera
Hemispherical camera is composed of a hemispherical shield, built-in single panel camera and infrared lamp (optional). It is generally divided into colorful hemispherical camera, day and night hemispherical camera and infrared hemispherical camera.

Precautions for use
Hemispherical cameras generally need 24-hour uninterrupted operation, so doing a good job in the protection of hemispherical cameras can prolong the service life of cameras and ensure the stability of camera pictures. For the installation of monitoring system, it is recommended to pay attention to the following points in detail.

Pay attention to the voltage stability of the hemispherical camera, otherwise it will affect the function of the picture and even cause the camera to be damaged;

*Often check whether the wire is damaged and aging to prevent the occurrence of abnormal conditions;
*Try to prevent direct sunlight or strong light for a long time to avoid damage to the camera CCD;
*For hemispherical cameras, the dust on the surface of the camera shell is often cleaned, and the shell shall not be opened as far as possible. If it needs to be opened, the power shall be cut off first;
*Establish hemispherical camera files for easy viewing and inspection in the future.
