Speed Bump LPR Camera That Works Well With Milestone LPR?

It's been my experience that speed bumps are best left as speed bumps.  I've seen trucks jam their brakes to dislodge poorly installed speed bumps.  Do you have options for another trigger such as a gate arm, a photoelectric sensor, inductive loop traffic sensor, or in-camera motion sensing?

you need a camera which make photo of the License-Plate when a truck or car cross the speed bump?

Hanwa(Samsung) - SNO 6084R

Axis - P13 series

Hikvision - DS-2CD4A26FWD

Dahua has also LPR camera`s with outputs but they aren't supported yet by Milestone, which I don't like because we only install Dahua cameras.

But licenses for Milestone are to expensive and the programm isn't really easy to use.

P.S: i search at Milestone under Corporate so i don't know which version you are using.

I installed a ANPR (AutomaticNumberPlateRecognition) from Dahua , where i selected a green motion area with a yellow recognition area to automatic get all licenseplates from that yellow area. 

Not the best quality, something wrong with Youtube.
