Hi, I'd like to install an outdoor ip camera for a house with only 3G internet (no wired broadband available). So I'd want a camera that works with a 3G internet signal, but with optional movement detection, as I don't want to receive email alerts every time a tree branch moves, etc. I might also install a second camera inside the house, with movement detection. So the 2 cameras using one 3G simcard. I may also want the option of recording continuous video images, about 10 hours a day. Would I need a HDD recorder or is it possible to upload everything to the cloud? What kind of setup would be best? Could I connect a wifi router using my 3G simcard to give the signal to 2 or more cameras? And finally, do you think 10 Gigas per month of 3G internet would be sufficient in this case? Thank you in advance!
