I have 2 of these cameras.
In order to capture people approaching my door I have "Sensitivity" set at 3 and "Record motion that lasts" at 0.5 seconds.
Quite often I'll realise that I haven't received a notification & no motion has been recorded - annoying if I miss a delivery for example.
When this happens I check the settings and both cameras have changed to "Record motion that lasts" 1 second. Which is far too slow to capture motion.
They aren't updating so why might these settings change themselves?
