Thanks for the replies. Yes, I just checked the firmware history and noticed that the firmware my camera is using is old. I had thought it would be newer because I just bought it.
Is it safe to upgrade the firmware through the android app or should I flash it manually seeing that the current firmware is over a year old?
Edit: I found a recent thread where someone reported that updating the firmware on the V3 bricked their camera. Person detection not working 10/26, no tags or notifications - #19 by abrons2011
So I would prefer to not update the firmware. I also went through the firmware logs and did not see anything related to improving motion detection.
