SEANHAWG 1 Posted October 25, 2011 The pulsating is due to the DVR compression. It is fairly common but is usually not near as noticeable as in that video that you posted of the Samsung camera. My guess is that the pulsating wont look as bad if you put it in Auto Day/Night mode where it will make the camera turn to B/W at night where the noise wont be so bad. It usually looks worse with a noisier picture. Share this post Link to post Share on other sites
martop1 0 Posted November 8, 2012 This is an old thread but it helped me trace a fault with a couple of my analogue cams, its the kind of fault that drives people insane, slow moving lines through the some cams on the monitor, I use a pc based recorder with BI software and for best part of the yesr it worked ok. I have 4 wired cams and one mp IP cam but these rolling lines only become noticable a few days ago, ive pulled cameras and power supplies and tested them on my bench, tested the cables too, nada, nothing wrong, put everything together again and the rolling lines began, almost at random, I almost gave up on this because nothings wrong with the cams, wiring or the pc or power supplies, then a few days ago I read through this entire post because I am upgrading a couple of my cams to samsungs and am getting a bead on other folks experiances. I got as far as the post way back where touching bnc connectors are mentioned and wadda ya know, my problem was caused by the bunch of bnc connectors running the pc card. Now when I built the pc I purposely made a 8 hole bracket to hold the bnc's in a neat line but one of them was touching another as it had drooped. Ok, it wasnt a dvr problem but during this post various suggestions where mentioned and one of those helped me. Thank you ! Share this post Link to post Share on other sites
