I have a Telpix dome camera http://www.telpix.com/camera/dome/50dn/
There are two round pods that can be adjusted with a screwdriver. and 8 dip switches. The dip's are for setting AGC, Flicker, etc. But I'm not sure what each one corespondes too, and the sane goes for turnable pods.
Any one have experience. I could call the distributor, but was trying to avoid the hassle.
UPDATE: I called Tepix, and they had no idea what I was talking about. But they told me who makes them. http://www.powert.net/products/cameras/dome/standard/large/pdl50dn/
