Hi to all of you that struggle to set the kguard remote view. I know it is an old post but hoped to help others like me. I've had the same problem as Nigel and this is what I followed and it worked.
or you type kguard setup on youtube and see the step by step guide posted by "dvrmaster".
Other than that for the kguard iphone remote view you put the same details but make sure that you change the password on the dvr (network settings) with the one you use on the iphone. Oterwise it won't work. Now it all works fine and it is quite simple when you know what you are doing. It took me 4 days to figure it out and hope that my post will save you some time.
