Camera is out of the box in that I just mounted and set it up. The trick with license plate capture with this camera is to set the max shutter at 1/200th and gain about 75. Do this for night, and daytime use the standard default exposure. You can set different settings on this camera in the image menu, the top option, set it time switch instead of auto switch. Then you can set the start/end time for day and night exposure (this is not related to day/night IR filter switch). Also, i set WDR during the day when there's a lot of contrast from the sun, but set WDR off at night.
As for this shot, I picked it because the big headlights and it pointing toward the camera. Most of my plate capture are not as close to the curb and headlights not pointed towards the camera.
