IPC-HFW5241E-Z12E What is going wrong?

yep :) i turned the iris down, maybe move up to 1/2000 shutter speed?
 
depend of the car speed for day i use this :

But you can use manual settings to fix Gain , you have to test

Its only 1/2000. During the daytime with the range being 0 - .5s it will never hit 1/2000 anyway except at dawn and dusk when it starts to get dark. It will be much faster than that during daylight hours. If I were to force it to 1/2000 during daytime it would be overexposed.
 
the value of the shutter will go from 1/2000 to infinity. If the sky is gray, the shutter will not slow down because its adjustment range is between 0 ms and 0.5 ms!
you must consider the average speed of the vehicles to adjust the shutter

I'm not sure I follow. As I understand it, the range value lets camera adjust the shutter speed as needed. So setting the lower value to zero allows it to operate as fast as possible when needed (during daylight) but allows allows it to slow down a bit when daylight begins to fade. I have it capped at 1/2000 as the slowest I want it to run during my daytime profile. I have a script that flips the camera to its nighttime settings 30 minutes before sunset. Those settings are vastly different than my daytime settings.

Yes you have understood the setting correctly if you put a value between 0 and 0.5 it means that the shutter will vary between 0 milliseconds and 0.5 milliseconds, so 0.5 is the slowest setting. But ... if one day the sky is gray 0.5 may be a little fast, especially if your vehicles are not moving fast! In my street the vehicles are traveling at a maximum of 50 km / h so I have a setting of 0 - 2 ms and I never have a problem with noise in the image even when the sky is gray as often in winter. Today the camera sensors are constantly evolving, the 5442 series is an excellent series from Dahua with 1 / 1.8 "sensors if you try the same settings with a 1 / 2.8" sensor you will have a bad image with these settings. .

Ok I understand. I may play with a 1/1000 setting during the day now that you have peaked my interest!

yes the best way to master everything is to do tests, tests and more tests :)

What is also important is the angle of the camera that must be respected, a maximum angle of 30 degrees vertically and 20/30 degrees horizontally.
And 200 pixels / meters to have good results.
if you have a resolution of 1920 X 1080 the maximum width of the scene must not be greater than 9.6 meters or you have to use more zoom.
1920 / 9.6 = 200 pixels.
