Common malfunctions
1. Infrared hemisphere series machines have poor image illuminance, whitishness or bright white aperture at night.
This phenomenon is caused by improper assembly of the machine. During assembly, the photosensitive device (photoresistor) is too far away from the hemisphere, which will cause the infrared light to start incompletely.
Causes the machine to have poor night illumination; the image appears white or bright white aperture phenomenon is mainly because the infrared light emitted by the infrared light-emitting tube is refracted to the lens through the dome cover
As a result, the solution to this phenomenon is to avoid refracting the infrared light to the surface of the lens. A sponge ring is usually used to isolate the lens from the infrared light.
Be sure to close the dome cover to the foam ring.
2. The night vision type infrared waterproof camera has normal images during the day and turns white at night
This phenomenon is generally caused by reflectors in the environment of the machine or used in a small space. It is caused by the reflection of infrared light. The first thing to do to solve this phenomenon is to
Determine whether there are reflectors in the use environment, and improve the use environment as much as possible. Secondly, check whether the effective infrared distance of the machine is the same as the actual use distance.
Should; if a long-distance infrared machine is used in a small space, the machine image will become white due to the strong infrared light.
