Hello! I had a Guardian cctv system fitted about 7 years ago by a friend of a friend and suddenly my settings have altered and I can't get it to go back to how it was originally set up! It doesn't seem to be recording anymore and playback is stuck on 3 dates. I downloaded the manual online but it's too complex for me. I'm desperate to get it back to how it was as I rely on it for safety as there's been a few break in recently down my road. I'm in south Birmingham.
