Welcome to the forum.
I am back to 155 on my cameras, or rather one is down to like 70.80 degrees or so, but thats done by fitting another lens ( 8 mm ) to the camera.
I have done some experimenting on the digital zoom of the camera, and all seemed to be working allright.
But there is really only one way to get things a little closer and thats using optics.
Here is a fresh video from the x camera with the 8 mm lens, as you can see/ feel it give a more up and personal experience, and in the footage you can read plates ahead of you just about as far as you can in the car usiog your eyes.
I think its really cool to have this in the windscreen, but you really got to have a wide angle camera there too cuz you loose a lot on the side.
On the other hand having been experimenting with this lens for some weeks now it seem to me that your chance of capturing a plate is higher at least in low light and weather like rain.
I would like a better 8 mm lens, this one is not a high grade lens, still its not all that bad.
In this video first you get the 155 degrees, and after that the same from the camera with the 8 mm lens.
And another one with me comming up on a beemer-boy at a intersection, as you can see the rear of the BMW fill the screen just about as it do in my little snub nosed car
