The cameras work, but stopped recording a few days ago. I just noticed it today when I clicked “Quick Playback” and it didn’t work. The power has gone out numerous times the previous couple of weeks (weather!) and I’ve had to reset the date/time about four times. Each time, it started recording again, except sometime between last Wed (9/12 and 9/15), while I was out-of-town. How do I get it to begin recording again (blue dot in corner of each frame)?
