Hi All,
I have a Dahua SD5A425XA-HNR.
At night, it has a strong IR light and lights the scene well. What I've discovered of course is that since licence plates are highly reflective, they are overexposed and unreadable. Default Exposure Compensation is set at 50. (Scale 0-100). This works brilliantly except for the licence plates. I can change it to 0 then plates read well, but the scene is dark. This is a zoom camera that is directed by another overview cam.
The security issue is suspicious vehicles parking for periods of time up to 2 hours. I need both licence plates as well as a well lit scene.
So, I was looking to make a rule on my software (NXWitness) that would reduce the exposure via a htpp/api request for the first 2 minutes of the alert for example, and then to change back to standard exposure.
Does anyone have any experience in adjust a Dahua camera exposure via http?
Cheers,
Tristan
