Does Anyone have some advise or a good settings for the Color4K-X 2.8mm? I messed around with mine and I'll post a picture where I have my settings and it's the best I found that works at night and day time for clearness. I was wondering if there's another way I can tweak these cameras even more? About 20ft I zoomed in and could barely read a license plate not sure if that's normal or not with these style of camera's. I'm always willing to try differnt settings to see hope someone can help thanks.

That isn't the way LPR works....except on TV. You might get away with a little digital zoom, but not much.

You need optical zoom not digital zoom. You might get away with a little digital, but not much.

We need higher focal length cameras to make the field of view basically be the size of a car.

Your field of view is WAY TOO BIG. You have a 2.8mm or 3.6mm wide angle lens. That is good for plates at maybe 4-6 feet unless the car is parked with lots of light and then you might stretch it to 15ish feet. At 20 feet you need about a 10mm lens

Regarding plates, keep in mind that this is a camera dedicated to plates and not an overview camera also. It is as much an art as it is a science. You will need two cameras. For LPR we need to OPTICALLY zoom in tight to make the plate as large as possible. For most of us, all you see is the not much more than a vehicle in the entire frame. Now maybe in the right location during the day it might be able to see some other things, but not at night.

At night, we have to run a very fast shutter speed (1/2,000) and in B/W with IR and the image will be black. All you will see are head/tail lights and the plate. Some people can get away with color if they have enough street lights, but most of us cannot. Here is a representative sample of plates I get at night of vehicles traveling about 45MPH at 175 feet from my 2MP 5241-Z12E camera (that is all that is needed for plates):

And since the 4K/X cannot see infrared, you would need stadium quality light to get plates at night.

See the LPR subforum.
