I think that's the most valuable information for the OP Jim.Fair enough, I have the Swann system with the 4Tb hard drive and the 800 analogue (I think resolution cameras) I wish I'd gone for the 1080HD digital version (I think) as visually its not that impressive. Its quality well made stuff and easy to install and set up, it has 4 cameras and option to fit another 4 and it links to my phone etc. it has IR for night time viewing but I just feel the image quality is a little too poor to get a really positive ID on a potential intruder etc.
The cheap stuff (and not really that cheap) is actually one of the items that you really do waste your money buying cheaper.... but it's really only good info coming from people who have already made the mistake.
