I have a Hik ds2cd2232-i5 with a 4mm lens. I'd like to put a 6mm lens in it but I haven't found a source for them. Does anyone know where to get them? thanks

There's so much to choose from and different levels of quality........... Anyway, I'm looking for an outside dome camera with IR that can see 80' out and about 40' horizontal. After I have it set up I wouldn't need to change it so I don't need PTZ. I could easily run the video and power to a PC. Wouldn't ever need to call it up on my cell phone or remote view it though. The one concern I have is that there would be a light source on one edge of the field of view at night. Would that screw up the night picture? Any camera/setup recommendations most appreciated. thanks
