Hi
I have an application where I am running custom Linux code that grabs images and processes them. I need to be able to discard images where the ambient light level is too low to produce reasonable quality images.
With previous cameras I have done this by measuring the brightness of the image, but with the HIKVision, image brightness can rise as ambient light falls. When it is quite dark, the images still have a lot of noise that makes the image look brighter than it should.
Has anyone found a way to interrogate the cameras with software to read status, shutter speed, etc etc?
