What is the effective distance of cameras in public places? In the case of street lights at night, can a camera of more than ten meters see the face of the Chu people clearly?

1. The effective distance of the lens depends on the focal length and precise focusing of the lens. 2. Portrait shooting at night, as long as the naked eye can see it, the camera will definitely see it, that is to say, if there is light reflection, the camera will definitely receive light. Use a slow shutter only when the light is dim. If the light is very dark, the slowest shutter speed of the camera is 30 seconds, which is not enough to shoot a clear portrait. It is recommended to use door B and open the shutter until it is considered successful.
