AWB and AE settings in "tricky" situation

Recommended Posts

Hi,

 

I have a couple of Sunell anti-vandal dome cameras mounted at a height of ~ 5m overlooking an inner yard. Outside the fence, lets say maybe 8-10 meters from the cameras are the city's street lights. They are sodium-vapor lamps emitting a reddish/yellow light. The building is made out of bricks, amplifying the red hue.

This image pretty much describes the situation: 278323_1.jpg

 

During daytime, each camera works great, but at nigh, when the lights turn on each image has a different tint. Its definitely something wrong with auto-exposure and/or WB.

 

For WB i can choose form:

AWB-PRO,

AWB-TEMP,

AWB-AI,

AWB-GW,

AWB-CCT

 

The options for AE are:

Smart-AE

Global

Center

Center Weig,

BLACK Light,

Front Light

Lower 1/3.

 

Each camera also has an Wide Dynamic Range option, albeit digital.

 

What are the differences between each WB option and AE? Which one should i choose in my situation?
