First, the ball machine uses power: AC24V. The input voltage of the dome will be indicated on the base of the dome or the corresponding location.
Second, the inside of the ball machine is precision optics and electronic devices. In the process of transportation, storage and installation, it is necessary to prevent incorrect operation methods such as heavy pressure and severe vibration, otherwise it may cause damage to the product.
Third, please do not disassemble the internal components of the dome, so as not to affect the use, there are no user-repaired parts.
Fourth, the use must comply with various electrical safety standards, with the dedicated power supply that comes with the machine. RS-485 and video signals should be kept at a sufficient distance from high-voltage equipment or cables during transmission. If necessary, prevent lightning protection and surge protection.
5. Do not place the high-speed ball directly for outdoor use to avoid the rain or damp of the ball machine. Please do not use it in wet places. Assuming that it is installed outdoors, a sealed enclosure must be used, and it is absolutely forbidden to use it alone in the open air.
6. Do not use this product outside of the specified temperature, humidity or power supply specifications.
7. Regardless of whether the dome camera is powered on, do not aim the camera at the sun or an extremely bright object. Do not aim the camera for a long time or monitor the bright stationary object.
8. Do not clean the main body of the intelligent high-speed dome camera with a strong or abrasive detergent. When cleaning the dirt, it should be cleaned with a dry cloth. When the dirt is not easy to remove, it can be wiped clean with a neutral detergent.
9. Intelligent high-speed dome cameras should be used with care and should be protected from shock or vibration. If used improperly, it will be damaged.
10. When installing an intelligent high-speed dome camera, install it in a position that is sufficiently durable.
XI. Assume that there is dust on the lens. Please use special lens paper to wipe.

Double-Convex Spherical Lens
Double-Convex Lens, also named Bi-Convex Lens,composing of two convex surfaces, has a positive focal length. DCX Lens is most suitable where the object and image are on opposite sides of the lens and the ratio of the image and object (conjugate ratio) distances is between 0.2 to 5. It is used in beam expanders,projection optics systems, optical viewers applications etc.
We also supply kinds of plano-convex spherical lenses,plano-concave spherical lenses,bi-convex spherical lenses,bi-concave spherical lenses,meniscus spherical lenses,special spherical lenses,achromatic spherical lenses,ball lenses,sphere lenses etc..
