I worked it out in the end, sorry if I was a Dumbo, its my age and lack of messing with stuff like this, I used to be in IT support but that was many many years ago, was good to get my brain working again to be fair, everything is easy when you know how, must congratulate you and everyone else on the excellent instructions and posts that people contribute,
.
I have 2 DS-2CD2032F-I updated the one as per instructions (number 2 tomorrow) went well (when i eventually got me little brain around it)
Thank you very much!!!
I have one other query though I have 2 DS-2CD2045FWD-I which I can live view through Chrome (on local network) but my old DS-2CD2045FWD-I has no live view any ideas??
