Outdoor camera recording in day but NOT at night

In the daytime, when my outdoor camera detects motion, it makes a recording and sends a notification. Perfect.

At night, this is what happens:

1) when I put it in spotlight mode, it detects motion and the spotlight comes on, but it doesn't make a recording or send a notification

2) when in night vision mode, the leds blinks to indicate motion detected, but it doesn't make a recording or send a notification

There is a security light about 60 feet away from the house. The light itself is not in view, but some of the area is partly lit. See attached image.

I don't have this problem with my 2 outdoor cameras on a different system at a different house. Idon't know what's wrong. Help please?!?!

 What do you suggest?
