spinder 0 Posted June 27, 2013 Hi all. My client is having an issue with his 16-ch. Zmodo DVR: He has 11 cameras installed which all display fine when the system is set to show all cameras. However, when the cameras are called up individually or the system is set to sequence mode, 4 of them flicker in and out and shows a "no signal" message on those 4 channels. Any answers out there? Urgent help needed. Share this post Link to post Share on other sites
