I have the swann 882004 hd system, about 6 months now. The system is flawless except for one little annoyance. Every so often a particular camera will glitch by that I mean frame loss for split second at times will flash no video. can be very annoying at times. There will also be text that flashes above camera number. It reads 1080p 30, I know that's res and frame per second any idea why this is happening? I've tried everything to eliminate this issue, thank you, Charles scott, mikemscott@hotmail.com
