difference between LPR CCD modules and standard day/night ?

[HeadsUp 0]

Hi people

 

i have spoken to a few manufacturers about obtaining LPR camera modules and i have a feeling that the same base CCD modules and board is used for both LPR use and standard day/night CCD's

 

obviously there will be different settings used in WDR settings to cancel out headlight flaring

 

can anyone confirm this or are there too many models covering a wide scope of applications between manufacturers ?

 

opinions please ??

 

note : i am not including ANPR cameras in the above statement , just basic LPR CCD's

They are essentially the same. There are two types of LPR cameras that I know of but if I am not up to date, please correct me:

 

1. Regular camera - regular day and night camera with DSP and IR LED tweaks to optimize high contrast images for easier license plate reading.

2. Ambient Light Rejection camera - companies like Bosch and Pixim manufacture specialized license plate reading cameras.

To answer your question, YES they are made of identical or similar image sensors and DSPs.
