Received the camera in excellent shape. Opened the box and went through the configuration up to the step where the camera should connect to the cellular network - where it wouldn‘t read the QR code on my phone. Restarted the process several times, and even tried joining the WiFi network, but no dice. Let it charge overnight and tried again, but still no luck. Called customer support and went through the process again, they suggested trying the Kentfaith app on a tablet with a bigger screen, and if it didn't work then I should return it. I tried it on the tablet and again the camera would not connect to either the cellular or WiFi network (it wouldn't read the QR code on the tablet either). I am returning this one and will re-order another to see if the problem persists. I'll update my review after I get the replacement.
April 25 update. Received the replacement camera and successfully got it set up. I had the same problem and learned you can reset the camera by pressing and holding the SYNC button for 8 seconds. I was able to get it to join my WiFi network first. Tried to get it on the cellular network but had issues again. Finally set the camera in the window with flat side up and was able to get it to connect to cellular after another 8-second reset. I think my problem was that I was setting it up on my desk with the flat surface down (camera upside down) and that was blocking the internal antenna. The first unit was probably fine, the meat-machine interface (namely me) was the issue for doing it wrong. Lessons learned: do the setup with the camera right-side-up, and if you have problems press the SYNC button for 8 seconds to do a reset. (The 8 second trick is not documented). Looks like we'll be in good shape, I am a satisfied customer
