Background
All WUUK products support B&W night vision with infrared LED lights.
When the camera turns on the infrared LEDs at night, it is prone to problems such as unclear night vision images, "fog", and "aperture/bright spots". Generally, they occur because of the specific environments and scenes.
This article mainly introduces the common causes and solutions to poor night vision.
I. The night vision is blurry
Analysis:
The monitoring environment is too large or empty, with few reflective objects and low ambient illumination, which may cause dark and blurry night vision.
Solution:
1. If it's convenient, you can supplement the light properly, but don't make the light directly hit the lens.
2. Kindly try to adjust the angle of the lens or change the location of the camera.
II. The night vision is "foggy" and dark
Analysis:
When the camera is installed on the wall(or ceiling & eaves), if the angle is too biased towards the wall, the infrared light reflected by the wall will be too strong, and the wall will be overexposed. If the wall is overexposed, the camera will keep the overall average brightness of the picture by reducing the exposure time of the shutter, so the other side of the picture will be too dark.
Solution:
1. Kindly try to adjust the angle of the lens and move the lens a bit away from the wall.
2. Try to install the camera in other spots.
III. "Spots" or "Aperture"
Analysis:
There is an obstruction near/ in the front of the lens (whether it appears on the screen or not) or a strong light source, which will reflect infrared lights back into the lens, causing an aperture.
Solution:
1. Make sure that the protective film has been removed completely.
2. When installing, try to avoid obstructions such as cables/cables, brackets, poles, utility poles, branches, cupboards, etc. near/ in the front of the lens.
3. The lens should maintain a certain angle with the wall, ceiling, beam, etc. Kindly try to adjust the angle of the lens and test if the same situation persists.
4. If it is installed near light sources such as street lamps, spotlights, and light box advertisements, it should maintain a certain height difference from the light source.
