Hi

Thank you for your help. I have the mode set to 'Auto' in the live view and 'Smart Mode' int he settings.  I have this problem on both the front and back cameras but not the doorbell. 
 

it seems the LUX sensitivity isn't triggering at the right levels to switch to night mode. 
 

Unfortunatley the wall is a painted white wall and I can't move the camera away from this. I can turn off the living room light to test if this changes the mode. This would be the source of light that reflects off the white wall. 
 

Can the image light level be averaged out for the whole image and not just pick an area to decide on the light level? Or allow us to change the sensitivity?
 

As others have said, maybe automate the two options from dusk-till-dawn depending on location. This could be picked up from the same source that allows the light bulbs to come on and off at this time. 
 

For the record, during a movement event the spotlight changes to colour when it should do. It is just viewing in the app that doesn't change.

Hi Wayne. 
 

I can confirm that the light level does not automatically switch within live view with no lighting outside or reflected on the wall. 
 

Here it is without the light leaking though the window (all lights off).

Hi Wayne

i had a chat with them earlier in the year and they said it was faulty so I bought another one and this does the same. 
 

Both the front garden and back garden react this way. I can force the night view but that means every time I want to monitor my garden (when no movement has triggered it) I open the app to darkness. I then have to change the light mode to "night" from "auto". 
 

I see others mention this too. I believe the cameras aren't switching light modes in the app when viewing them. 
 

There are other users with the same experience as me. Here is one user:

I have cleaned my camera IR sensors. The cameras did this from new.
