When the camera detects in the dark the infrared clicks, and then I get an error message THUMBNAIL NOT GENERATED. I have reinstall the camera to the system. Could this be a battery issue?
Welcome to the forums! It definitely could be (and most likely is) a battery issue. Replace the batteries and let us know how you make out.
I got that error a couple of times. I think the app told me to power cycle the hub. Another error I got from a camera (after half of an image was recorded) was to power cycle the camera. I’m not sure if the app told me to do it or the FAQ.
