In the future:
1: Do you plan on selling the "old" GS911 some years after the new is for sale?
(not everyone will need the added functions and web based interface- not all will want to pay the higher price?)
2: If you do plan on selling both units I hope both will have regular updates - free or not :-)
(the "old" for at least some years into the future)
3: I see a possible problem when owners of the "old" upgrade and want to sell the old on the web.
That will open up the market for counterfeit units :-(
Is it possible to make a register where a possible buyer can check if the unit they want to buy is a original one?
I do see lots of problems with that, legal, personal protection and so on.
Ok, I admit it was a silly question and suggestion
Guess the only safe solution for buyers are to buy locally- so the seller can prove the updates work and the GS911 is a proper one.
