We installed a second Stick Up Cam and today our motion video only recorded 1-2 seconds. The video was set to 30 seconds and it worked for many months. It did this since the second camera was installed. I looked at the record time and it was set to 30, so I thought, maybe wake it up and change it to 20 and see what happened. Lo-and-behold, that change caused the front camera to record 20 seconds. I checked the rear camera, still 1-2 seconds. I did the same thing and it started working correctly again.
Just an FYI to help others who might be stuck.
