Just FYI, I bought the 1.3 MP 20x no-infrared PTZ from milkisbad some time last year when it was on sale and tried it with the longest exposure settings. It does brighten up the image a lot at night but anything that moves much is pretty blurred. For the best night-time use, get a model with infrared built in!Could you PM me with your catalog and prices. I'm particularly interested in the high end, low light, PTZ domes.
