License Plates at Night

Postby tscheifler » Sun Nov 04, 2018 11:10 pm

I'm using a IP2M-858W. At night, I am unable to read license plates. The headlights and taillights seem to "overwhelm" the picture. Can anyone recommend settings that would improve this issue?

Suggestions:
Go to settings/camera/configuration/BLC mode,select HLC mode and adjust it. There are many other factors that will affect reading the license plate including zoom, distance, angle from camera to plate, speed of car, exposure time, and IR light. If you have to use IR and the plate is too bright, try using IR setting of ZoomPro or Smart IR. Also, on the 858 camera, you can try changing the Iris setting found at the PTZ controls. Google camera license plate (or something similar) to learn more.

Thanks Jack! I was looking for the HLC config last night but had not yet located it.
I will try variations of the items you mention.
Thanks again.

After trying many different settings and combinations of settings, I was able to get great night time plate images by simply changing the Exposure to Manual - Shutter Speed 1/1000. All other camera settings I left as the default values.
Here is a sample image of two vehicles approximately 20 feet from the camera. For privacy, I have masked the right half of each plate. The plate on the left is a vehicle moving at approximately 25 mph. The plate on the right is a parked vehicle.
