I just got the 5 camera Blink XT setup and it’s all working, I can access the live videos and take snapshots, etc. However, it’s not detecting motion on ANY of the cameras and hasn’t saved a single video in the entire 4 days I’ve had it running. I’ve had deliveries that should have been caught on at least 2 cameras. I’ve left the house numerous times, there have been deer, neighbors, etc. Not a single recording. Any suggestions?
