Thanks to pozello at post #88 and #90. I'm using his settings. Day images are very good, but night images just ok depending on the speed of the car. I noticed around the time the ir's go off or on the focus and images aren't very good. I'm zoomed in about 60 feet @8.2x at about 30 degrees to the direction of cars going past. Camera is mounted about 8'-6" high. I have it currently set at 15fps. When I review the images it can take looking at a few frames to get all the characters identified - especially at night. I will continue to experiment and tweak the settings.Decided to try one of the v2 cams as LPR. Can anyone share ideal configuration? I seem to be getting either overexposed or underexposed picture when attempting with manual configuration.
I was thinking about it, but that means reducing lifespan of the leds possibly and extra 6 watts of power usage...can you just leave it in black/white mode 24/7? If you have another camera that can see the road in the daytime it'll get the vehicle's color for you.. loosing the focus on a plate reader is really detrimental.
var http = require('http'),
Cam = require('onvif').Cam;
new Cam({
hostname: <CAMERA_HOST>,
username: <USERNAME>,
password: <PASSWORD>
}, function(err) {
this.gotoPreset(5)
});
});
how about setting up separate presets that differ only in the focus for day/night and find a way to switch between them automatically at dusk/dawn?
yes, I set focus to manual in camera's UI and created separate presets for day & night
(same view - differ only in focus), then in BI camera properties/ schedule/ event schedule...
add events relative to sunrise & sunset that switch the cam to the appropriate preset.
