Its not my Microwave its the neighbours and it is close to the receiver, I have just finished hardwire connecting my old video camera to the box and will give that a run just to prove to myself that it is not the DVR. Will then try getting the camera and receiver closer together as you suggest. Thanks again

Thanks for the replies it looks like I will have to get hard wired cameras for recording purposes. Regards Woody

ispy, Thanks for the reply, I am sure that most of the signal loss is due to microwave useage - you get the tell tale lines on the screen. I have tried ugrading the arials to 9dBi High Gain, which improved reception slightly. I have it set to permanent record not motion. Here is the full spec of the system.

They are an old couple that we help a lot and know that they do all their meals by microwave - the video loss ties in with their meal times, our microwave causes the same problem but we hardly use ours.

Hi, This is my first post. I have a MU055 4Ch DVR and have 2 wireless cameras attached, However I keep finding it stops recording if I get a video loss signal - normally caused by next doors microwave oven which they use a lot. Has anyone else had this problem ? If so is there a fix? Regards Woody
