IPC-B54IR-Z4E-S3 optimisation for night time LPR

[brianthesnail]

apologies if this is in the wrong forum - mods please point me elsewhere if appropriate

following all the recommendations in these forums I've bought a IPC-B54IR-Z4E-S3 from andy, specifically to dedicate to the job of LPR.
Its located at a height of about 4m (adjacent to an upper floor window of 2 storey UK house) about 30m from the target spot. Angle of about 30 degrees to the traffic.
Its on full zoom.

In the day its giving good results (depending on vehicle speed , mostly they are slow because they have to be)
In the night I have blown out reflection on the plates.

I only installed this cam yesterday so still learning how to tune this camera- in order to get a headstart, is there a set of best practice settings for a dedicated LPR use case?
I've already dialled the shutter speed down to 10msec, should I go lower? what else to tweak?

these are UK plates.

thanks

Use the Manuel Mode and a higher shutter. Illuminator mode : manuell 100/100%

Try 0 - 0,5 or 1 shutter and lower gain.

so I now have for Exposure set6tings:
:

not clear to me how to use that gain setting? what are the two values for? on other cameras I only have one value for gain.

I've now got a much darker picture which I know is expected - not had any cars yet (late night bad weather everybodys hiding) so will leave it recording overnight and see

I wonder sometimes if it might be worth it for some to spend the extra money on an actual lpr vs trying to make something that’s not meant for it do the job. I guess it comes down to what is your time worth

Actually you have to go thru the same process to some extent. The only difference is the LPR can read and log the plates.
