I have a Provision DVR that connects to internet via ethernet. The DVR is located at a job site that has no utilities only a generator for power that turns off during the end of the workday. What's the easiest way to get internet to the DVR so I can view it remotely? I'm not on site everyday so I need something that works automatically and doesn't need manual input to work once power at generator is turned on. Also would like the cheapest option with the least equipment to discourage theft. I can get a SIM card with unlimited LTE internet.
I tried huawei E960 but Ethernet was very poor. I would get 35Mbps upload when sim was in LG G5 phone but less than 1mbps when sim was in device.
I later tried huawei B683 it was better but only marginal. I get 2mbps upload when sim on device but 35Mbps upload when sim in LG G5 phone.
Keep in mind that both routers are 3g where phone is 4g so the difference in speed is understandable.
Anyone have a better device in mind or even a different solution?
I was thinking of using a cell phone and USB tethering but I would need to get an adapter to Ethernet and I'm not sure if once that ethernet is plugged to dvr if it will charge phone. Because if it doesn't and generator is off on the weekend the phone might die then when it starts might not automatically USB tether without manual input.
