Walking in front of both cameras I can see myself in Live view, however, neither camera is recording - even though it's within the timeframe of the schedule I've set, and detection is set to both vehicles and motion with a sensitivity of 10.  Yesterday, one camera failed to take any recordings, and the other just seven (normally it's several hundred per day) - and the settings haven't changed.  Camera 1 regained some 30% charge via its solar panel over the weekend (No schedule and detection off) yet yesterday morning (Monday 30/09) I awoke to find that overnight it had almost all its charge and this morning it has powered itself off having run out of charge.  I am now in a situation where neither camera is recording as it should and one camera has lost all its charge for no reason I can think of (overnight detection was set to off, and no recording schedule was set).

I believe both cameras are suffering from some sort of fault as they were both working fine and as expected for two months from 20th July until just over a week ago!

I removed both cameras from their attachments and, when I opened them op some drops of water came out.  The black covers on both cameras had been securely fixed, and the waterproof gaskets seemed to be intact.  I recall there being quite a severe and long-lasting thunderstorm over the weekend when they started misbehaving, with strong gusts of wind and a lot of heavy rain so I'm wondering whether the water could have got in at some point during that period.
