Your set-up issue is not speed. I don’t know what it is but it isn’t speed. Very little data is handled during set-up. A few handshakes, passwords, serial numbers, and the odd snapshot is all that’s passed. Probably not even a single mb in the roughly 10 minutes it takes.
Persist, get it all connected, and then do tests to see if it’s good enough for you, before you return it, or decide on an alternate data plan. Talk to support if necessary. Don’t tell them about your speed, initially, or they will latch onto that, and blame it, even if it isn’t relevant. Just let them help you get connected, and then do all your own performance tests. If unhappy, return it after that.
Despite earlier posts saying 1.5mb is not enough, I am running a four camera system, with a terrible upload rate, of around 0.7mb/s and it works flawlessly, other than I get a notification, periodically, from Blink, saying my upload speed is a little slow, and to consider doing various things to fix it, but I haven’t, and the system keeps going, doing what it should. No way I can get a better speed, it’s in a shed in a field, so I have to live with what I have. It’s MiFi, in a bad 4G area, but it still works.
Bear in mind the system is meant to be able to handle traffic from up to 10 cameras, all at once, so one or two is manageable for even my system, and all four never trip at once anyway.
If you’re in a good spot for 4G, Joel’s suggestion is definitely a good one. I very nearly replaced my home wired internet with a 4G MiFi router, when I had one on test at home, and I was getting 40mb/s upload from it. I did actually order it, and got it delivered, but in the end the lack of an unlimited data plan didn’t work for me, so I cancelled the contract in the early stages, whilst still possible. Weeks after I’d cancelled, nearly everyone started offering unlimited data, on their MiFi plans, but by then it was too late, I had an alternate wired provider in place, which was cheaper still.
Sure, if you’re uploading something else, maybe a youtube video, then okay, maybe you won’t have enough bandwidth left, but chances are, when you really need it to work, you won’t be at home, uploading stuff. If you will, then it might not work, but test it, once set up.
