Hi ive been looking at what a good lens would be for a arecont 5105. need to be between 3-5mm and its a indoor camera with quite a bit of light. Ive looked at a few and not sure what to go with. seen a few that are IR, day and night but im not sure if you can use a IR lens on a NON ir camera (sorry im sorta new to this), its a bit confusing being that camera is a 5 megapixel and there is few lens' that are rated to 5 megapixel.
Any information would be great. Thanks
