ANPR Camera Lane Limit

[jannes258]

Hi all

I'm currently looking at the following ANPR camera.
DHI-ITC413-PW4D

What would be the lane limit of this camera, I've searched everywhere but can't really find a proper answer.

The reason for the question being, I want to put it up next to a busy road with the hope of it capturing plates from both lanes.

Any feedback or help would be greatly appreciated!

Have a great one!

Maybe because its a variable focus camera.

You're gonna have to do maffs and a bit of trial and error based on your scene.

Specs are pretty well spelled out

Generally these are installed above the lanes of traffic and about 14ft+ above, so if you're going to have it on the side of the road, its going to be a little different.
Height will be a key factor, and the two model versions have much different lenses. Depending on the width of the lanes and the speeds you may have trouble getting both lanes (it is two lanes right?
