Can I setup blink at Mom"s home w/o internet and router? But monitor from my internet and router from my lication?
No. It is a minimum requirement that the cameras and sync module are connected to the internet, at all times.
How would the images/videos get to the Blink cloud, and then to your device, without internet at the location of the camera?
One way you can accomplish this is with a Netgear JetPack from Verizon. If you have Verizon and an unlimited plan you can add Wifi Hotspot service for $10 a month. You can pick up a JetPack for $65. I am running 6 cameras currently with my JetPack. Do not buy Verizon current hotspot offering. It isn’t very good.
