I have a spotlight camera battery installed facing down the footpath to the font door. It was installed to maximise the duration and clarity of recording of people coming to the front door as the recording from the video doorbell was not always clear enough in all ambient light conditions.
Until recently, all worked fine with recordings by the spotlight camera starting every time someone started up the path to the front door.
However in recent weeks, it has not recorded every instance of motion up the path (missing 60%) of events and sometimes only picks up motion from the front door (i.e. when leaving the house).
In addition, on occasions at night, the spotlight is not activated by motion events.
I have tried increasing the motion sensitivity to about 60%. I am wary of increasing the sensitivity further as even with people only mode enabled, the local cats keep triggering the camera, and I want to reduce the number of false alerts.
Live view shows that the camera viewing angle is still OK. Battery level is OK. So clearly the motion sensor is not being triggered by all motion events.
