I have a DS-2CD2185FWD-I camera. And by day i'm happy with it, but at night I have a small light on just a few meter away. When that is on I have trouble with my night vision. I can only see clear a few meters. Is there a guide or something that could help me get the best off my camera with the light on? Or should I switch to a different type of camera. Any tips? There is a person left in the picture, but he's very hard to see. I don't think its good enough with light off and only night vision as well..
