Hello everyone - look for some help. I purchased the swann 2 camera and DVR from bnq the other day - I have a few cameras from an old system I got a few years back. I installed both the Swann cameras along with a brand new cable but older camera I had. They all work perfect during the day but when it starts to get dark one by one they switch to night vision but after 20 minutes they all cut out completely and I get no picture at all.
my main question would be is this because the other camera? And is there a way of resolving the issue?
