Hi,
To be honest I hadn't really thought about the future in terms of firmware support etc. I was too busy feeling annoyed with myself by thinking I've wasted my time and money on something I could have achieved with my K series.
My original plan was to buy and keep the M series and then stick a spare hard drive into my K series and sell it on eBay.
Obviously I could still do that. I'm just annoyed that I couldn't get what I wanted using that damn dongle. I cannot understand why Hikvision have this dongle option DVR if it doesn't work as expected (or maybe it would if I knew how?).
I've got about a week to make up my mind but I'll definitely be taking your advice seriously.
FYI, I have one 5MP TVI camera (hence the reason for buying a turbo model) and two Hikvision 8MP IP cameras - model DS-2CD2H85G1-IZS.
Thanks for your help.
Sean
