I have managed to configure my Ezviz camera gui to access the contrast/brightness/DVL/BLC settings etc.

Now the dark objects that pass through my yard at nighttime with the IR camera light on are not always detected due to the lack of contrast, dark on dark even with a wall light on.

I am assuming increasing the contrast of the camera setting for night time will help distinguish these objects.

Is this correct?

Shall I keep brightness at default and increase contrast?
Also looking at enabling the BLC setting as there is an exterior light right in the center on the back wall and seems to focus on this. The back light compensation I believe will enhance the other areas. Not sure on the left/right/up/down/center options for BLC.
I put it at 'down' for now. Does this mean anything below the light will be enhanced?

Thanks
