i currently have a system. 4 bullet cameras w/480 lines of hor res. but it is good at only 40 ft night monitoring, the problem is that it is not clear enough, what i see on the monitor as i watch real time is not what i get after recording. so, is it the camera or the dvr. i want to catch the bad guys on my street. night time is when they come out and i need clarity. can someone help pleas.
