I am new to this but I brought this one >> http://www.newegg.com/Product/Product.aspx?Item=N82E16881338096 I also replaced two of the cameras with these >> http://aposoniccctv.com/index.php/camera/fixedlens/193 After finding this site and doing some reading I should have done it different. Anyway the picture looks ok but really not as clears as I thought it should be.I have installed each camera at all four corners of the house. My question is I would like to replace two of the camera with one that has a clearer picture. Any suggestion. BTW I want it hard wired and not cost a arm and a leg...Thanks, Mike
