1,6 meg upstream is quite a lot.I was thinking if I can use WLAN connection??That would save my money I think.By the way I'm from Poland and where I live,i mean district, there is no good internet provider,especially with that upstream.I call to our Geovision distibutor and he said that I need minimum 1Mbit/s for one cam.For 16 Channel DVR it's 16 Mbit/s upstream.
