You only need to use one HDD and I would also go with the 4mp version. Where do you want to order them? On Alibaba you have to wait 1-2 months if you want to buy them there.
I'm really looking forward to the new models. I definitely need a Vario Tioc for the garden to replace my 3849r1. If they even have an alarm, they might be better than the Tioc cameras or not?
I have someone who is selling a 5442T-ZE. Unfortunately, he doesn't know whether it's the new or old model. Do any of you happen to know which one it is?
