I did a test 1st to make sure I saw the light. ..
I unplugged the cam for over 2 hours. ..
Plugged it in, saw a light at say 75% of what it should be. Looked in ipcamviewer, actually see infrared light.
Looked again after 30 to 45 minutes. It was more faint than before.
Checked around hour 3, nothing.
Will swap p.s. next. (Although I do have this on extension cord (same one for last 3 years). I just suspect the ir is burnt out and tired. We'll see.
