Well I got round to setting up the system & i have to say it was fairly simple, though camera locations added to the drama, but all in all happy with the outcome.
I will say that i was surprised how easy it was to get remote viewing on phone & tablet, it was really easy to setup when viewing over the home wifi, but even to view over the phone was relatively simple, actually for me to do inside half an hour shows how really simple it was.
I havent actually worked out the recording & playback side, but have it set on motion record ( i think)
So for those who where also considering cameras I would give these a thumbs up.
I paid $650, but did a interweb search & somewhere had them for under $500, so at that price pretty good imo
Edit:
There is a capability for having an intergrated alarm system, but that would be well & truely above my pay grade
